Abstract

The heater allows re combustion several times in the burner of the exhaust gases to reduce the pollution output. The collector (2) for the gases in the combustion chamber (1) re injects them into the grill (8). The gas can be re injected with fresh air (4) into the combustion chamber to allow reburning and feeding into the incandescent grill area. The additional fresh air can be controlled by a heat sensor and an electrically driven turbine forces the mix back into the combustion chamber via passages (6,7).

Description

La présente invention concerne les chaudières type chauffage central consommant des combustibles solides comme le bois.The present invention relates to central heating type boilers consuming solid fuels such as wood.

Cette invention permet de rebrûler en deuxième combustion les gaz restant inflammables qui se trouvent dans la chambre de combustion (1).This invention enables the remaining flammable gases which are in the combustion chamber (1) to be re-burned on second combustion.

Dans tous les types de chaudières existantes à ce jour (combustion montante, descendante dite inversée), la température de la chaudière doit être maintenue à un degré prescrit, ce qui implique une combustion plus ou moins intense.In all types of boilers existing to date (rising combustion, so-called reverse combustion), the temperature of the boiler must be maintained at a prescribed degree, which implies more or less intense combustion.

Cette combustion est régulée par un calorstat qui donne plus ou moins d'air nécessaire à la combustion.This combustion is regulated by a calorstat which gives more or less air necessary for combustion.

Si l'air admis est insuffisant, la combustion est incomplète et des gaz inflammables s'échappent par la cheminée ce qui provoquent des émanations de fumées lourdes et très colorées, polluantes, qui salissent le conduit d'évacuation et qui entraînent une perte de calories.If the intake air is insufficient, combustion is incomplete and flammable gases escape through the chimney, which cause heavy and very colored, polluting fumes, which dirty the exhaust duct and which cause a loss of calories. .

Dans les chaudière dites à "Turbo-combustion", lorsque que le turbo fonctionne la combustion du bois est intense, mais dès que la température prescrite est atteinte, celui-ci s'arrête et coupe la combustion. Les gaz imbrûlés s'évacuent par la cheminée en la salissant et entraînent une perte de calories.In boilers called "Turbo-combustion", when the turbo is burning the wood is intense, but as soon as the prescribed temperature is reached, it stops and cuts off the combustion. The unburnt gases escape through the chimney, making it dirty and causing a loss of calories.

Le dispositif objet de l'invention permet d'éviter ces désagréments.The device which is the subject of the invention makes it possible to avoid these inconveniences.

En effet, il permet d'aspirer les gaz dans la chambre de combustion (1) par un capteur en forme d'entonnoir (2), ces gaz sont reconduits par le canal (3) et à l'aide d'une turbine électrique (5) dans le foyer de braise incandescente.Indeed, it makes it possible to suck the gases into the combustion chamber (1) by a funnel-shaped sensor (2), these gases are carried back through the channel (3) and using an electric turbine (5) in the glowing embers hearth.

Une addition d'air (4), régulée par un calorstat est nécessaire pour la première et deuxième combustion, les gaz additionnés d'air sont propulsés par la turbine électrique (5) et reinjectés à la base du foyer (8) par les passages (6 et 7), ces gaz plus ou moins irzflammables rebrûtent en passant dans la braise.An addition of air (4), regulated by a calorstat is necessary for the first and second combustion, the gases added with air are propelled by the electric turbine (5) and reinjected at the base of the hearth (8) by the passages (6 and 7), these more or less non-flammable gases are burnt by passing through the embers.

L'excédent des gaz s'évacue par le conduit à filmées (10). Les gaz complètement brûlés ne sont plus colorés, ne laissent plus aucun dépôt de suie ou de goudron, ne polluent plus et permettent de réaliser des économies de combustible. The excess gas is evacuated through the filmed conduit (10). Completely burnt gases are no longer colored, no longer leave any soot or tar deposits, no longer pollute and allow fuel savings.

Ce dispositif: objet de l'invention peut être utilisé dans tous les cas ou la combustion doit être régulée par plus ou moins d'addition d'oxygène à l'air.This device: object of the invention can be used in all cases where combustion must be regulated by more or less addition of oxygen to the air.

Ces applications sont particulièrement intéressantes pour tous types de chauffage au bois réglables par admission d'air. These applications are particularly interesting for all types of wood heating adjustable by air intake.
