Patent

CA 2234645

The present invention relates to a furnace for burning solid organic fuel and more precisely sulphur-containing solid fuel with a high volatile-product concentration. The furnace comprises a burning chamber (1) having a cold funnel with an outlet (4). A lower blowing device (5) is located under the cold funnel outlet (4) and along the entire width of the chamber, wherein said device together with a downward oriented burner (2) generate a whirl zone in the lower section of the burning chamber (1). The furnace also comprises a sorbant inlet channel (6) for the uptake of sulphur, wherein said channel (6) is located below the burner (2) and has its longitudinal axis intersecting the whirl zone. The sorbant is mixed to the fuel and introduced into the chamber (1) through said channel (6).

Cette invention concerne un four permettant de brûler des carburants organiques solides et, plus précisément, des carburants solides contenant du soufre et ayant une forte teneur en produits volatiles. Ce four comprend une chambre de combustion (1) qui comporte un entonnoir froid avec une ouverture (4). Un dispositif (5) de soufflerie inférieur est monté sous cette ouverture (4) et sur toute la largeur de la chambre. Ce dispositif, ainsi qu'un brûleur (2) orienté vers le bas, vont créer une zone de tourbillons dans la partie inférieure de la chambre de combustion (1). Ce four comprend également un canal d'alimentation (6) en sorbant en vue de l'absorption du soufre. Ce canal (6) se situe en-dessous du brûleur (2), et possède un axe longitudinal qui croise la zone des tourbillons. Le sorbant est mélangé au carburant avant d'être introduit dans la chambre (1) par l'intermédiaire dudit canal (6).
