Abstract (en)
[origin: WO8202759A1] Means controlling the emitted heating effect from a furnace which is fired with solid fuel. In the furnace the fuel (11) is fed to a zone of combustion (13) where it is combusted with excess air. Characteristic for the invention is that the fuel (11) is made to create an approximately evenly thick, air pervious layer, in said zone (13). During the combustion the air of combustion is forced from one side of said layer (13) to the other, the over pressure being sufficient for optimal combustion, but independent on the emitted heating effect. The regulation against a decreasing heating effect value is carried out by means of a corresponding screening of the other side of the layer. The regulation against an increasing heating effect value is carried out by means of a corresponding exposure of the other side of the layer, which is equal with a decrease or increase, respectively, of the volume of the zone of combustion (13).
Abstract (fr)
Moyens de commande de la chaleur emise par un four a combustible solide. Dans le four, le combustible (11) est envoye dans une zone de combustion (13) ou sa combustion s'effectue avec de l'air en exces. La caracteristique de l'invention reside dans le fait que le combustible (11) est fabrique pour creer une couche permeable a l'air d'une epaisseur approximativement uniforme, dans la zone (13). Pendant la combustion, l'air de combustion est force de passer d'un cote de cette couche (13) a l'autre, la surpression etant suffisante pour obtenir une combustion optimale, mais elle est independante de la chaleur emise. La regulation contre une valeur decroissante de la chaleur s'effectue a l'aide d'un effet d'ecran correspondant de l'autre cote de la couche. La regulation contre une valeur croissante de la chaleur de chauffage s'effectue par une exposition correspondante de l'autre cote de la couche, qui est egale a une diminution ou une augmentation, respectivement, du volume de la zone de combustion (13).
