Description

DOMAINE TECHNIQUE GENERALGENERAL TECHNICAL FIELD

La présente invention concerne le domaine des installations d'incinération de déchets.The present invention relates to the field of waste incineration plants.

ETAT DE L'ARTSTATE OF THE ART

Les déchets, en particulier ceux issus des activités humaines (on verra plus loin une liste plus exhaustive), sont collectés, et s'ils ne peuvent être recyclés, ils sont selon les cas mis en décharge ou détruits par incinération, c'est-à-dire par une combustion aussi complète que possible, l'énergie libérée étant valorisable.Waste, in particular those resulting from human activities (we will see later a more exhaustive list), are collected, and if they can not be recycled, they are, depending on the case, landfilled or destroyed by incineration. that is to say, by a combustion as complete as possible, the released energy being recoverable.

Il est connu l'utilisation de fours oscillants pour assurer la combustion de déchets solides à caractéristiques énergétiques variables (i.e. des déchets avec des PCI, Pouvoir Calorifique Inférieur, très divers). Un exemple d'un tel four est par exemple décrit dans les documents EP0044370 , FR15781160A , FR1493907A ou encore FR2350136A1 . Le four comporte une « cellule » qui constitue une chambre de combustion allongée et inclinée, d'une forme généralement cylindro-tronconique s'étendant le long d'un axe longitudinal orienté légèrement vers le bas. La cellule est adaptée pour osciller voire tourner complètement le long de cet axe.It is known the use of oscillating furnaces to ensure the combustion of solid waste with variable energy characteristics (ie waste with PCI, lower heating value, very diverse). An example of such an oven is for example described in the documents EP0044370 , FR15781160A , FR1493907A or FR2350136A1 . The furnace has a "cell" which is an elongate and sloping combustion chamber of generally cylindro-frustoconical shape extending along a longitudinal axis oriented slightly downwardly. The cell is adapted to oscillate or even rotate completely along this axis.

Les déchets sont introduits dans la cellule par un système de poussoir qui débouche par un trou dans la face à l'extrémité la plus haute du cylindre (face arrière). La progression continue des solides dans la cellule est assurée par l'inclinaison de l'axe et le mouvement d'oscillation, jusqu'à sortir sous forme de résidus (produits de combustion) par la face opposée, à l'extrémité la plus basse (face avant).The waste is introduced into the cell by a pusher system which opens out a hole in the face at the highest end of the cylinder (rear face). The continuous progression of the solids in the cell is ensured by the inclination of the axis and the oscillation movement, until exiting in the form of residues (products of combustion) by the opposite face, at the lowest end (front face).

L'air de combustion circule à contre-courant jusqu'à un trou de sortie des gaz, ce qui définit trois zones successives indépendantes dans la cellule :

  • Une première zone de séchage des déchets,
  • Une deuxième zone de combustion, et
  • Une troisième zone de refroidissement des produits de combustion.
The combustion air circulates countercurrently to a gas outlet hole, which defines three independent successive zones in the cell:
  • A first area for drying the waste,
  • A second combustion zone, and
  • A third cooling zone of the combustion products.

Un tel four apporte satisfaction. La combustion des déchets est complète et homogène même si leurs caractéristiques énergétiques sont disparates, et ce sans pic local de température qui risquerait de faire fondre les cendres.Such an oven brings satisfaction. The combustion of waste is complete and homogeneous even if their energy characteristics are disparate, and this without a local peak of temperature that could melt the ashes.

Il serait toutefois souhaitable d'améliorer encore son rendement thermique, et d'optimiser la flexibilité en agrandissant encore davantage la gamme de PCI acceptable, et ce sans complexifier l'installation et sans augmenter son coût.However, it would be desirable to further improve its thermal efficiency, and to maximize flexibility by further expanding the range of acceptable PCI, without complicating the installation and without increasing its cost.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION Structure de celluleCell structure

En référence à la figure 1a qui décrit un mode de réalisation préféré, la présente invention concerne une installation 1 d'incinération de déchets, en particulier des déchets ayant des PCI et des granulométries très variables.With reference to the figure 1a which describes a preferred embodiment, the present invention relates to a facility 1 for incineration of waste, in particular waste having PCI and very variable particle sizes.

Il peut s'agir de déchets organiques tels que des végétaux, des morceaux de bois, des résidus de scierie (chute, sciures), de la paille, des coques, des déchets ménagers tels que des papiers, des plastiques, des caoutchoucs, des déchets textiles, etc.It can be organic waste such as vegetables, pieces of wood, sawmill residues (fall, sawdust), straw, hulls, household waste such as paper, plastics, rubbers, textile waste, etc.

L'installation 1 comprend comme élément central une cellule 10 de combustion qui présente le rôle de four des déchets. En d'autres termes d'est une chambre de combustion. L'installation peut en comprendre plusieurs.The installation 1 comprises as central element a combustion cell 10 which has the role of furnace waste. In other words, is a combustion chamber. The installation can include several.

Elle s'étend le long d'un axe longitudinal entre une face d'entrée 2a et une face de sortie 2b. Ledit axe longitudinal est incliné (en particulier de 10 à 40° par rapport à l'horizontale) de sorte que la face d'entrée 2a présente une altitude supérieure à la face de sortie 2b. Ces axe longitudinal définit une direction principale de la cellule 10, orientée de la face d'entrée 2a vers la face de sortie 2b, cette direction correspondant au sens de progression des déchets dans la cellule 10. Dans la suite de la présente description, on parlera d'amont et d'aval de la cellule 10 en suivant cette direction, l'amont se situant ainsi vers la face d'entrée 2a, et l'aval vers la face de sortie 2b.It extends along a longitudinal axis between an inlet face 2a and an outlet face 2b. Said longitudinal axis is inclined (in particular 10 to 40 ° relative to the horizontal) so that the input face 2a has an altitude greater than the exit face 2b. This longitudinal axis defines a main direction of the cell 10, oriented from the entry face 2a to the exit face 2b, this direction corresponding to the direction of progression of the waste in the cell 10. In the remainder of the present description, speak upstream and downstream of the cell 10 in this direction, the upstream is thus located to the input face 2a, and the downstream to the output face 2b.

De façon préférée, la cellule 10 présente une forme sensiblement axisymétrique par rapport audit axe longitudinal, en particulier une forme cylindro-tronconique. Cela signifie que la cellule présente une section cylindrique et une section tronconique (i.e. conique étêtée), la section cylindrique étant en amont de la section aval comme l'on voit sur les figures. Les deux sections cylindrique et tronconique ont avantageusement des longueurs assez similaires.Preferably, the cell 10 has a substantially axisymmetric shape with respect to said longitudinal axis, in particular a cylindro-frustoconical shape. This means that the cell has a cylindrical section and a frustoconical section (ie conical head), the cylindrical section being upstream of the downstream section as seen in the figures. The two cylindrical and frustoconical sections advantageously have fairly similar lengths.

Outre les faces d'entrée et de sortie 2a, 2b, la cellule 10 présente une face latérale 11 qui s'étend sur toute sa circonférence, et qui est donc limitée longitudinalement par les faces 2a et 2b. la paroi latérale 11 peut être choisie en un matériau isolant thermiquement, mais comme l'on verra plus loin cela n'est pas nécessaire, ce qui permet de diminuer le coût global de l'installation et de la simplifier.In addition to the input and output faces 2a, 2b, the cell 10 has a lateral face 11 which extends over its entire circumference, and which is therefore limited longitudinally by the faces 2a and 2b. the side wall 11 may be chosen from a thermally insulating material, but as will be seen later this is not necessary, which reduces the overall cost of the installation and simplify it.

Comme expliqué on est en présence d'un four oscillant, c'est pourquoi la cellule 10 est mobile en rotation autour dudit axe longitudinal, et est donc adaptée pour osciller (l'amplitude angulaire du mouvement d'oscillation est avantageusement de quelques dizaine de degrés). Ce mouvement permet d'entrainer et de faire progresser les déchets dans la cellule 10 le long de l'axe longitudinal.As explained, it is in the presence of an oscillating furnace, that is why the cell 10 is rotatable about said longitudinal axis, and is therefore adapted to oscillate (the angular amplitude of the oscillation movement is advantageously about ten degrees). This movement allows to drive and advance the waste in the cell 10 along the longitudinal axis.

L'installation 1 comprend également des moyens 4, 5 d'introduction des déchets dans la cellule 10 via la face d'entrée 2a, ces moyens consistant par exemple en une conduite 4 s'étendant selon ledit axe longitudinal, équipée par exemple d'un vérin ou d'une vis sans fin pour l'introduction des déchets (système de poussoir), et en une trémie 5 stockant de manière intermédiaire les déchets qui descendent par gravité dans la conduite 4. Les déchets sont comme expliqués incinérés dans la cellule 10, et les produits de combustion (résidus, cendres, etc.) sortent de la cellule 10 au niveau de la face de sortie 2b où ils sont récupérés.The installation 1 also comprises means 4, 5 for introducing the waste into the cell 10 via the inlet face 2a, these means consisting for example of a pipe 4 extending along said longitudinal axis, equipped for example with a jack or a worm for the introduction of waste (pusher system), and a hopper 5 intermediately storing waste that descends by gravity in the pipe 4. The waste is as explained incinerated in the cell 10, and the products of combustion (residues, ash, etc.) leave the cell 10 at the outlet face 2b where they are recovered.

L'installation 1 comprend également des moyens 3a, 3b d'alimentation de la cellule 10 en air de combustion et/ou de refroidissement. Par air de combustion, on entend un comburant pour la combustion des déchets. Par air de refroidissement, on entend de l'air mis en échange thermique avec les produits de combustion avant qu'ils arrivent au niveau de la face de sortie 2b, de sorte à récupérer l'énergie thermique de ces produits pour valorisation tout en refroidissant ces produits pour faciliter leur récupération.The installation 1 also comprises means 3a, 3b for supplying the cell 10 with combustion and / or cooling air. By combustion air is meant an oxidizer for the combustion of waste. By cooling air is meant air in heat exchange with the combustion products before they arrive at the outlet face 2b, so that recover the thermal energy of these products for recovery while cooling these products to facilitate their recovery.

De façon préférée, l'air de combustion et l'air de refroidissement sont le même air atmosphérique (contenant du dioxygène en quantité naturelle), mais on comprendra que l'on peut par exemple utiliser de l'air enrichi en dioxygène comme air de combustion et/ou un gaz inerte comme air de refroidissement.Preferably, the combustion air and the cooling air are the same atmospheric air (containing oxygen in a natural quantity), but it will be understood that it is possible, for example, to use oxygen-enriched air as the air of oxygen. combustion and / or an inert gas as cooling air.

Si l'air de combustion et l'air de refroidissement sont le même air atmosphérique on peut utiliser un seul circuit d'air, mais de façon préférée l'installation 1 présente des moyens 3a d'alimentation de la cellule 10 en air de combustion et des moyens 3b d'alimentation de la cellule 10 en air de refroidissement distincts. Comme l'on verra plus loin, cela est en particulier utile pour maintenir des températures différentes entre l'air de combustion et l'air de refroidissement.If the combustion air and the cooling air are the same atmospheric air one can use a single air circuit, but preferably the installation 1 has means 3a for supplying the cell 10 with combustion air and means 3b for supplying the cell 10 with separate cooling air. As will be seen later, this is particularly useful for maintaining different temperatures between the combustion air and the cooling air.

Dans une mode de réalisation préférée, la cellule 10 définit successivement trois zones le long de l'axe longitudinal :

  • Une première zone de séchage des déchets,
  • Une deuxième zone de combustion, et
  • Une troisième zone de refroidissement des produits de combustion.
In a preferred embodiment, the cell 10 successively defines three zones along the longitudinal axis:
  • A first area for drying the waste,
  • A second combustion zone, and
  • A third cooling zone of the combustion products.

Ces trois zones peuvent être plus ou moins de la même longueur. On comprendra que l'air de combustion est introduit au niveau de la deuxième zone et que l'air de refroidissement est introduit au niveau de la troisième zone. Cela sera également décrit plus en détail plus loin.These three areas may be more or less the same length. It will be understood that the combustion air is introduced at the second zone and that the cooling air is introduced at the third zone. This will also be described in more detail below.

Dans tous les cas, le ou les moyens 3a, 3b peuvent consister en un ou plusieurs ventilateur.In any case, the means 3a, 3b may consist of one or more fans.

Par ailleurs, l'installation 1 comprend un conduit 6 d'évacuation des fumées, i.e. des gaz produits par la réaction de combustion. Ce dernier est situé au-dessus de la cellule 10, sensiblement en position médiane (au niveau de la deuxième zone), et s'étend radialement par rapport à la cellule 10. La paroi latérale 11 de la cellule 10 présente une ouverture permettant aux fumées de s'échapper vers le conduit 6. On note que l'air de refroidissement s'étant réchauffé par contact avec les produits de la combustion remonte la cellule et s'échappe également via le conduit 6.Furthermore, the installation 1 comprises a duct 6 flue gas, ie gases produced by the combustion reaction. The latter is located above the cell 10, substantially in the middle position (at the second zone), and extends radially with respect to the cell 10. The side wall 11 of the cell 10 has an opening allowing the fumes to escape to the duct 6. It is noted that the cooling air heated by contact with the products of the combustion goes up the cell and also escapes via the duct 6.

Des moyens de récupération de la chaleur des fumées (tels qu'un échangeur de chaleur) peuvent être disposés le long du conduit 6 pour valoriser l'énergie des fumées, par exemple pour vaporiser de l'eau en vue de faire tourner une turbine pour générer de l'électricité.Smoke heat recovery means (such as a heat exchanger) may be arranged along the duct 6 to enhance the energy of the flue gases, for example to vaporize water in order to rotate a turbine to generate electricity.

Les fumées peuvent être traitées dans une chambre auxiliaire située également long du conduit 6.The fumes can be treated in an auxiliary chamber also located along the duct 6.

On comprendra que des moyens tels que des joints mobiles assurent l'étanchéité entre la cellule 10 mobile et le conduit 6 fixe.It will be understood that means such as movable joints seal between the movable cell and the fixed conduit 6.

Enveloppe creuseHollow wrap

La présente installation 1 se distingue en ce qu'elle comprend en outre une enveloppe creuse 12a, 12b disposée autour de la paroi latérale 11 (externalement) de sorte à recouvrir au moins 50% de sa surface (avantageusement au moins 75%, encore plus avantageusement au moins 90%, et encore plus avantageusement sensiblement 100%). En d'autres termes, l'enveloppe creuse 12a, 12b entoure la cellule 10 de façon concentrique.The present apparatus 1 is distinguished in that it further comprises a hollow envelope 12a, 12b disposed around the side wall 11 (externally) so as to cover at least 50% of its surface (advantageously at least 75%, even more preferably at least 90%, and even more preferably substantially 100%). In other words, the hollow envelope 12a, 12b surrounds the cell 10 concentrically.

Le fait que l'enveloppe 12a, 12b soit creuse lui permet de recevoir de l'air circulant, et l'espèce l'air de combustion et/ou de refroidissement. Dans un mode de réalisation préféré illustré par les figures et qui sera décrit plus en détail plus loin, l'enveloppe creuse présente deux parties distinctes, i.e. étanches l'une par rapport à l'autre, c'est-à-dire sans interconnexion fluidique.The fact that the envelope 12a, 12b is hollow allows it to receive circulating air, and the species air combustion and / or cooling. In a preferred embodiment illustrated by the figures and which will be described in more detail below, the hollow envelope has two distinct parts, ie sealed with respect to each other, that is to say without interconnection fluidics.

La première partie est une partie primaire 12a disposée en amont de la cellule 10, et la deuxième est une partie secondaire 12b disposée en aval de la cellule 10. La partie primaire 12a est avantageusement plus étendue que la partie secondaire, c'est-à-dire que la partie primaire 12a de l'enveloppe creuse recouvre au moins ladite section cylindrique de la cellule, et une partie de la section tronconique, alors que la partie secondaire 12b ne recouvre qu'une partie de la section tronconique. Plus précisément, la partie primaire 12a s'étend avantageusement sur environ deux tiers de la longueur de la cellule 10, et la partie secondaire 12b sur environ un tiers de la longueur de la cellule 10. En pratique, cela correspond à entourer les deux premières zones (séchage et combustion) avec la première partie 12a, et tourner la troisième zone (refroidissement) avec la partie secondaire. Cela permet ainsi d'utiliser la partie primaire 12a de l'enveloppe creuse pour faire circuler l'air de combustion, et la partie secondaire 12b pour faire circuler l'air de refroidissement circule.The first part is a primary part 12a disposed upstream of the cell 10, and the second part is a secondary part 12b disposed downstream of the cell 10. The primary part 12a is advantageously more extensive than the secondary part, that is to say that is, the primary portion 12a of the hollow envelope covers at least said cylindrical section of the cell, and part of the frustoconical section, while the secondary portion 12b covers only a portion of the frustoconical section. More specifically, the primary portion 12a advantageously extends over approximately two thirds of the length of the cell 10, and the 12b in about a third of the length of the cell 10. In practice, this is to surround the first two zones (drying and combustion) with the first portion 12a, and turn the third zone (cooling) with the abutment. This thus makes it possible to use the primary portion 12a of the hollow envelope to circulate the combustion air, and the secondary portion 12b to circulate the cooling air circulates.

Dans tous les cas, on comprendra que ladite enveloppe creuse 12a, 12b en une ou deux parties permet de faire circuler autour de la cellule 10 de l'air (de combustion ou de refroidissement) destiné à y être injecté, et ce avant son injection.In any case, it will be understood that said hollow envelope 12a, 12b in one or two parts makes it possible to circulate around the cell 10 air (combustion or cooling) intended to be injected, and this before its injection .

Cela permet d'améliorer sensiblement le rendement énergétique en faisant diminuer les pertes. Plus précisément, l'air de combustion et/ou refroidissement est préchauffé avant d'arriver dans la cellule, ce qui améliore le rendement. Cela peut sembler paradoxal dans le cas de l'air de refroidissement, mail il faut comprendre que la partie primaire 12b de l'enveloppe creuse met en échange thermique les produits de combustion et l'air de refroidissement ce qui améliore leurs transferts thermiques. Ainsi, l'impact de l'air de refroidissement est amélioré : les produits sortent moins chaud (davantage refroidis) et l'air de refroidissement capte plus de chaleur (il atteint une température plus élevée en sortant par le conduit 6, ce qui fait que plus d'énergie sera valorisable).This significantly improves energy efficiency by reducing losses. More specifically, the combustion air and / or cooling is preheated before arriving in the cell, which improves the efficiency. This may seem paradoxical in the case of cooling air, it must be understood that the primary portion 12b of the hollow shell heat exchange combustion products and cooling air which improves their heat transfer. Thus, the impact of the cooling air is improved: the products exit less hot (more cooled) and the cooling air captures more heat (it reaches a higher temperature leaving the duct 6, which makes that more energy will be valuable).

De plus, l'enveloppe creuse 12a, 12b agit comme isolant thermique de la cellule 10 en lieu et place de la paroi latérale 11 qui n'a pas besoin d'être en un matériau couteux, et de fait permet une réaction de combustion réalisée dans des conditions adiabatiques.In addition, the hollow envelope 12a, 12b acts as thermal insulation of the cell 10 in place of the side wall 11 which does not need to be of expensive material, and in fact allows a combustion reaction to be performed under adiabatic conditions.

De façon préférée, l'enveloppe creuse (en particulier chaque partie 12a, 12b) est connectée fluidiquement aux moyens 3a, 3b d'alimentation de la cellule 10 en air de combustion et/ou de refroidissement (respectivement aux moyens 3a d'alimentation de la cellule 10 en air de combustion et aux moyens 3b d'alimentation de la cellule 10 en air de refroidissement) via un joint tournant 13a, 13b.Preferably, the hollow envelope (in particular each portion 12a, 12b) is fluidly connected to the means 3a, 3b supplying the cell 10 with combustion air and / or cooling air (respectively with the means 3a for feeding the combustion air cell 10 and the means 3b supplying the cooling air cell 10 via a rotary joint 13a, 13b.

Similairement, l'enveloppe creuse (en particulier chaque partie 12a, 12b) est connectée fluidiquement à la cellule 10 via au moins un orifice 14a, 14b (une buse) traversant la paroi latérale 11.Similarly, the hollow envelope (in particular each portion 12a, 12b) is fluidly connected to the cell 10 via at least one orifice 14a, 14b (a nozzle) passing through the side wall 11.

En référence à la figure 1c qui sera décrite plus loin et qui représente une vue mise à plat de l'enveloppe 12a, 12b (i.e. les extrémités base et haute de la figure sont normalement connectées de sorte à retrouver la forme axisymétrique), les orifices 14a de la partie primaire 12a sont avantageusement uniquement sur la moitié aval (i.e. en vis de la deuxième zone), alors que les orifices 14b de la partie secondaire 12b sont avantageusement repartis sur toute la longueur de la partie secondaire 12b.Referring to Figure 1c which will be described later and which shows a flattened view of the envelope 12a, 12b (ie the base and top ends of the figure are normally connected so as to regain the axisymmetric shape), the orifices 14a of the primary portion 12a are advantageously only on the downstream half (ie facing the second zone), while the orifices 14b of the secondary portion 12b are advantageously distributed over the entire length of the secondary portion 12b.

Premier mode de réalisation : simple enveloppeFirst embodiment: simple envelope

En référence aux figure 1a et 1b, dans un premier mode de réalisation l'enveloppe creuse 12a, 12b est « simple » c'est-à-dire qu'elle ne présente qu'une épaisseur de veine de circulation d'air.With reference to figure 1a and 1b in a first embodiment, the hollow envelope 12a, 12b is "simple", that is to say that it only has a thickness of airflow vein.

On note que chacune des parties primaire 12a et secondaire 12b peut présenter cette structure, le cas échéant indépendamment de l'autre. Dans la suite de la présente description on décrira l'enveloppe 12a, 12b complète mais on comprendra que la présente description se transpose exactement pour chacune des parties 12a, 12b. A ce titre, les éléments avec une référence numérique se terminant par « a » seront compris comme ceux de la partie primaire 12a, et ceux se terminant par « b » leurs équivalents de la partie secondaire 12b.It is noted that each of the primary 12a and secondary 12b may have this structure, if necessary independently of the other. In the remainder of this description the complete envelope 12a, 12b will be described, but it will be understood that the present description is transposed exactly for each of the parts 12a, 12b. As such, the elements with a numerical reference ending in "a" will be understood as those of the primary part 12a, and those ending in "b" their equivalents of the secondary part 12b.

Plus précisément, dans ce mode de réalisation l'enveloppe creuse 12a, 12b présente des canaux aller 120a, 120b et des canaux retour 121a, 121b, disposés de telle sorte que l'air circulant dans ladite enveloppe creuse 12a, 12b parcourt les canaux aller 120a, 120b puis les canaux retour 121a, 121b avant d'être introduit dans la cellule 10. Pour reformuler encore, l'air est injecté par les moyens 3a, 3b dans les canaux aller 120a, 120b, les parcourt et est transféré dans les canaux retour 121a, 121b qui desservent les orifices 14a, 14b donnant dans la cellule 10.More precisely, in this embodiment the hollow envelope 12a, 12b has forward channels 120a, 120b and return channels 121a, 121b, arranged so that the air flowing in said hollow envelope 12a, 12b passes through the forward channels. 120a, 120b then the return channels 121a, 121b before being introduced into the cell 10. To reformulate again, the air is injected by the means 3a, 3b in the forward channels 120a, 120b, travels and is transferred to the return channels 121a, 121b serving the orifices 14a, 14b giving in the cell 10.

De façon préférée, lesdits canaux aller et retour 120a, 120b, 121a, 121b sont sensiblement coplanaires avec l'axe longitudinal de la cellule 10, c'est-à-dire qu'ils s'étendent parallèlement à l'axe longitudinal à l'angle près du à la forme tronconique de la cellule (et ainsi ils s'étendent légèrement radialement), mais jamais tangentiellement.Preferably, said forward and return channels 120a, 120b, 121a, 121b are substantially coplanar with the longitudinal axis of the cell 10, that is to say that they extend parallel to the longitudinal axis at the center of the cell. angle close to the frustoconical shape of the cell (and so they extend slightly radially), but never tangentially.

Ainsi l'air parcourt les canaux aller 120a, 120b en allant vers la face d'entrée 2a (i.e. il remonte la cellule 10), puis parcourt les canaux retour 121a, 121b en allant vers la face de sortie 2b (i.e. il redescend la cellule 10). Cela permet par exemple aux orifices 14a de la partie primaire 12a d'être en aval de cette partie primaire 12a (i.e. en deuxième zone).Thus, the air travels the forward channels 120a, 120b towards the input face 2a (ie it raises the cell 10), then travels the return channels 121a, 121b towards the output face 2b (ie it goes down the cell 10). This allows, for example, the orifices 14a of the primary portion 12a to be downstream of this primary portion 12a (i.e. in the second zone).

Comme l'enveloppe 12a, 12b est simple, chaque canal retour 121a, 121b est disposé entre deux canaux aller 120a, 120b. Cela est bien visible sur la figure 1b , qui représente deux coupes respectivement en partie primaire 12a et secondaire 12b (voir figure 1a les positions des coupes).Since the envelope 12a, 12b is simple, each return channel 121a, 121b is disposed between two forward channels 120a, 120b. This is clearly visible on the figure 1b , which represents two sections respectively in primary part 12a and secondary part 12b (see figure 1a the positions of the cuts).

Les canaux 120a, 120b, 121a, 121b peuvent alors être formés par des ailettes s'étendant radialement dans l'enveloppe creuse 12a, 12b, et définissant des parois azimutales des canaux (la paroi latérales 11 et la paroi externe de l'enveloppe 12a, 12b définissant leurs parois radiales).The channels 120a, 120b, 121a, 121b can then be formed by fins extending radially in the hollow envelope 12a, 12b, and defining the azimuthal walls of the channels (the side wall 11 and the outer wall of the envelope 12a , 12b defining their radial walls).

On note que de façon préférée, l'enveloppe creuse 12a, 12b ne comprend pas de canal retour 121a, 121b au voisinage de l'ouverture dans la paroi latérale 11 pour le conduit 6 d'évacuation des fumées, ce qui signifie que sur une portion angulaire « haute » de la cellule 10 (qui s'étend avantageusement sur 90 à 135°, en particulier environ 120° de la circonférence de l'enveloppe creuse 12a, 12b) il n'y a que des canaux aller 120a, 120b cote à cote.It is noted that, preferably, the hollow envelope 12a, 12b does not include a return channel 121a, 121b in the vicinity of the opening in the side wall 11 for the flue gas duct 6, which means that on a "high" angular portion of the cell 10 (which advantageously extends over 90 to 135 °, in particular about 120 ° of the circumference of the hollow envelope 12a, 12b) there are only go channels 120a, 120b side by side.

La figure 1c évoquée précédemment représente de façon très visuelle la portion sans canaux retour 121a, 121b.FIG. 1c evoked above represents in a very visual way the portion without return channels 121a, 121b.

En effet, il est souhaitable qu'il n'y ait pas d'injection d'air de combustion et/ou refroidissement en portion haute (uniquement en portion basse, sous les déchets), ce qui fait qu'il n'y a pas d'orifices 14a, 14b en portion haute.Indeed, it is desirable that there is no injection of combustion air and / or cooling in the upper portion (only in the lower portion, under the waste), so that there is no no orifices 14a, 14b in the upper portion.

Comme l'on voit sur les figure 1a, 1b et 1c, l'enveloppe creuse 12a, 12b comprend avantageusement une couronne de distribution 15a, 15b interconnectant les canaux aller 120a, 120b et les canaux retour 121a, 121b. Cette couronne 15a, 15b présente la forme d'un anneau et permet de redistribuer le flux si des orifices 14a, 14b étaient par exemple bouchés de sorte à éviter des surpressions.As we see on figure 1a , 1b and 1c, the hollow envelope 12a, 12b advantageously comprises a distribution ring 15a, 15b interconnecting the forward channels 120a, 120b and the return channels 121a, 121b. This ring 15a, 15b has the shape of a ring and redistributes the flow if orifices 14a, 14b were for example blocked so as to avoid overpressures.

Par ailleurs chaque canal retour 121a, 121b est avantageusement équipé d'une vanne 16a, 16b (c'est-à-dire d'un élément ouvrable/fermable) commandée en fonction de la position angulaire de la cellule 10.Moreover, each return channel 121a, 121b is advantageously equipped with a valve 16a, 16b (that is to say a workable / closable element) controlled according to the angular position of the cell 10.

Plus précisément, l'objectif est que malgré la rotation de la cellule 10 l'air soit toujours injecté sensiblement au même endroit : au plus bas de la cellule, sous les déchets.More specifically, the objective is that despite the rotation of the cell 10 the air is always injected at substantially the same place: at the lowest of the cell, under the waste.

Pour cela les vannes 16a, 16b sont commandées de telle sorte que le ou les canaux retour 121a, 121b situés sous les déchets à incinérer présentent des vannes 16a, 16b ouvertes, les autres canaux retour 121a, 121b présentant des vannes 16a, 16b fermées.For this the valves 16a, 16b are controlled so that the return channel (s) 121a, 121b located under the waste to be incinerated have open valves 16a, 16b, the other return channels 121a, 121b having valves 16a, 16b closed.

Cela est possible via un contrôle électronique ou tout simplement mécanique : il est possible que les vannes 16a 16b soient des éléments de type soupape prolongés par une tige telle qu'une poussée sur la tige ouvre la vanne 16, 16b, un ressort assurant son retour dans la position initiale de fermeture. Des éléments fixes peuvent être disposés autour de la cellule 10 de telle sorte que la rotation viennent faire appuyer ces soupapes sur les éléments fixes et les ouvrir lorsque dans la bonne position angulaire.This is possible via an electronic control or simply mechanical: it is possible that the valves 16a 16b are valve-type elements extended by a rod such that a push on the rod opens the valve 16, 16b, a spring ensuring its return in the initial position of closure. Fixed elements may be arranged around the cell 10 so that the rotation come to press these valves on the fixed elements and open when in the correct angular position.

Second mode de réalisation : double enveloppeSecond embodiment: double envelope

En référence à la figure 2 , dans un deuxième mode de réalisation l'enveloppe creuse 12a, 12b est « double » c'est-à-dire qu'elle présente deux épaisseurs de veine de circulation d'air.With reference to the figure 2 In a second embodiment the hollow casing 12a, 12b is "double" that is to say it has two air flow vein thicknesses.

Toute la structure du premier mode de réalisation est reprise, à la différence que les canaux aller 120a, 120b sont disposés de sorte à former une couronne autour des canaux retour 121a, 121b. En d'autres termes, la veine externe de l'enveloppe 12a, 12b n'est constituée que de canaux aller 120a, 120b, et la veine interne est soit composée uniquement de canaux retour 121a, 121b, soit d'un mix de canaux aller et retour 120a, 120b, 121a, 121b si l'on veut par exemple une portion haute sans canaux retour 121a, 121b, voir une portion interne identique à celle du premier mode de réalisation (i.e. avec une alternance de canaux aller et retour 120a, 120b, 121a, 121).The entire structure of the first embodiment is repeated, with the difference that the forward channels 120a, 120b are arranged so as to form a crown around the return channels 121a, 121b. In other words, the external vein of the envelope 12a, 12b consists only of forward channels 120a, 120b, and the internal vein is composed only of return channels 121a, 121b, or a mix of channels 120a, 120b, 121a, 121b, for example, if it is desired, for example, to have a high portion without return channels 121a, 121b, to see an internal portion identical to that of the first embodiment (ie with alternating forward and reverse channels 120a 120b, 121a, 121).

Une telle architecture améliorer encore l'efficacité énergétique puisque la veine externe agit comme second isolant thermique. Il est tout à fait envisageable de prévoir plus de deux épaisseurs mais cela augmente les pertes de charge et n'est pas forcément souhaitable.Such architecture further improves energy efficiency since the external vein acts as a second thermal insulator. It is quite conceivable to provide more than two thicknesses but this increases the pressure losses and is not necessarily desirable.

Il est à noter que comme l'on voit sur la figure 1b une enveloppe auxiliaire 17 peut être disposée autour de l'enveloppe creuse 12a, 12b simple ou double. Cette enveloppe auxiliaire 17 est distincte fluidiquement de l'enveloppe principale 12a, 12b et sert par exemple à la circulation d'un fluide caloporteur en échange thermique avec l'air de combustion et/ou de refroidissement circulant dans l'enveloppe creuse 12a, 12b, pour valorisation de l'énergie récupérée. Cela permet d'augmenter encore l'efficacité énergétique sans augmenter les pertes de charges. Les pertes thermiques résiduelles sont récupérées par le fluide thermique, ce dernier étant par de l'eau qui sera ultérieurement mise en échange thermique avec les fumées du conduit 6 pour vaporisation et alimentation d'une turbine (voir avant). Cela permet de préchauffer cette eau avec les pertes thermiques résiduelles. Alternativement un réseau d'eau sanitaire domestique peut par exemple être chauffé.It should be noted that as we see on the figure 1b an auxiliary envelope 17 may be arranged around the hollow envelope 12a, 12b single or double. This auxiliary envelope 17 is fluidly distinct from the main envelope 12a, 12b and serves for example for the circulation of a heat transfer fluid in heat exchange with the combustion air and / or cooling circulating in the hollow envelope 12a, 12b , for recovery of recovered energy. This allows to further increase the energy efficiency without increasing the pressure drops. The residual thermal losses are recovered by the thermal fluid, the latter being water which will subsequently be heat exchanged with the fumes of the duct 6 for vaporization and feeding a turbine (see before). This allows to preheat this water with residual heat losses. Alternatively, a domestic sanitary water system may for example be heated.
