Abstract
Description
La présente invention concerne les chaudières de chauffage do mestiquescu collectives munies de brûleurs à dispositifs de compression d'air comburant et dont on se propose de réduire la consommation d'hydrocarbures tout en conservant la puissance calorifique nominale, en substituant du charbon de bois pulvérisé à la partie économisée d'hydrocarbures. I1 existe de longue date des chaudières brûlant du charbon de terre pulvérisé mais les installations nécessitent des dispositifs d'allumage, d'alimentation et d'évacuation de cendres compliqués ce qui a limité leur utilisation aux seules grosses centrales industrielles,
L'utilisation de charbon de bois permet une pulvérisation très fine des particules autorisant une fluidisation parfaite du carburant et la simplification des mécanismes d'alimentation et d'inflammation.The present invention relates to collective domestic heating boilers provided with burners with combustion air compression devices and for which it is proposed to reduce the consumption of hydrocarbons while retaining the nominal calorific power, by substituting pulverized charcoal for the saved part of hydrocarbons. There have long been boilers burning pulverized charcoal, but the installations require complicated ignition, supply and evacuation devices for ash, which has limited their use to large industrial plants only,
The use of charcoal allows a very fine spraying of the particles allowing a perfect fluidization of the fuel and the simplification of the feeding and ignition mechanisms.
L'absence ou la très faible teneur en cendres (1 à 2 %) supprime presque complètement les problèmes d'évacuation des imbrûlés. The absence or very low ash content (1 to 2%) almost completely eliminates the problems of evacuation of unburnt products.
L'augmentation du prix des hydrocarbures intervenue et nrévi- sible a rendu la calorie charbon de bois compétitive avec la calorie pétrole. The increase in the price of hydrocarbons which occurred and was inevitable made the charcoal calorie competitive with the petroleum calorie.
Le dispositif, objet de l'invention, comporte des véhicules capables de transporter le charbon de bois pulvérisé et de l'amener par voie pneumatique vers la trémie de réception et de stockage du client ainsi que de mesurer le poids livré, Les systèmes déjà en service pour les boulangeries étant simplement adaptés aux exien- ces propres au service du charbon de bois. The device, object of the invention, comprises vehicles capable of transporting the pulverized charcoal and of bringing it pneumatically to the customer's receiving and storage hopper as well as of measuring the weight delivered, The systems already in service for bakeries being simply adapted to those specific to the service of charcoal.
La trémie client, lorsaue la place dans la chaufferie est suffisante est unique, sinon on nrévoit deux trémies l'une primaire capable d'un stockage relativement volumineux pour assurer une autonomie de l'ordre d'un mois de fonctionnement et variable avec la puissance de l'installation et la proportion de fuel/charbon de bois adoptée. The customer hopper, when there is enough space in the boiler room, is unique, otherwise there are two hoppers, the primary one capable of relatively large storage to ensure autonomy of around one month of operation and variable with power of the installation and the proportion of fuel / charcoal adopted.
La seconde, située au dessus du brûleur à mazout est de petite taille (une journée de fonctionnement). Un système de transfert auto natique ou semi-automatique permet de remplir la petite trémie à partir de la grande. Le volume de la deuxième trémie chaudière est de l'ordre de 100 à 200 litres. The second, located above the oil burner is small (one day of operation). An automatic or semi-automatic transfer system makes it possible to fill the small hopper from the large one. The volume of the second boiler hopper is around 100 to 200 liters.
Selon une réalisation de l'invention le transfert d'une trémie vers l'autre est obtenu par transport pneumatique. According to one embodiment of the invention, the transfer from one hopper to the other is obtained by pneumatic transport.
Selon une autre réalisation, l'alimentation de la trémie chaudière est obtenue à partir de sac en papier de 50 à 100 litres, vidés directement dans la trémie par un système d'aspiration en circuit clos évitant l'émission de poussière dans la chaufferie et permettant la vidange complète des sacs, leur "rinçage' étant obtenu par un balayage d'air. La trémie équipée d'un agitateur ou de parois mouvantes empêchant la formation de voûte assure un écoulement continu de la poussière de charbon de bois vers un débimètre constitué par un couloir vibrant équipé d'un ou de plusieurs deversoirs de hauteur règlable. Ceci permet le dosage de la quantité de charbon injecté dans l'air aspiré nar le brûleur et injecté dans la chaudière.Certainsmodèles pourront avoir une injection modulable de gazoil en fonction de la présence ou de l'absence de charbon dans la trémie, ce qui assurera un chauffage normal en toutes circonstances. According to another embodiment, the supply to the boiler hopper is obtained from paper bags of 50 to 100 liters, emptied directly into the hopper by a closed-circuit suction system avoiding the emission of dust in the boiler room and allowing complete emptying of the bags, their "rinsing" being obtained by an air sweep. The hopper equipped with an agitator or moving walls preventing the formation of a vault ensures a continuous flow of charcoal dust to a flow meter consisting of a vibrating corridor equipped with one or more weirs with adjustable height. This allows the metering of the quantity of coal injected into the air sucked in by the burner and injected into the boiler. Some models may have a modular injection of diesel in depending on the presence or absence of coal in the hopper, which will ensure normal heating in all circumstances.
Le dessin annexé illustre à titre d'exemple un mode de réalisation du dispositif conforme à la présente invention. The appended drawing illustrates by way of example an embodiment of the device according to the present invention.
Tel au'il est représenté, le dispositif comnorte une trémie de chaudière(3avec son tuyau de remplissage a partir de la trémie de stockage2ou du sac de panier ou de tout autre conteneur ; un dispo (4) sitif de dosage du charbon vers le brûleur à mazout ; un couloir amenant le charbon dans la veine d'air aspiré par le brûleu5; une connection électrique assurant la simultanéité de fonctionnement entre le brûleur et le distributeur de charboA6et enfin une boite à cendres en forme de cyclone(7)pour récupérer les cendres les plus grossières précipitées dans le conduit de fumée. As shown, the device includes a boiler hopper (3 with its filling pipe from the storage hopper or the basket bag or any other container; a charcoal dosing device (4) for the burner oil-fired; a corridor bringing the coal into the air stream sucked in by the burner5; an electrical connection ensuring simultaneous operation between the burner and the charboA6 distributor and finally a cyclone-shaped ash box (7) to recover the the coarsest ash precipitated in the flue.
