Dispositif de combustion

Abstract

A combustion device including a combustion chamber, a primary reactor and a suction and exhaust tube for gases wherein the gas suction and exhaust tube passes through the primary reactor. In a preferred embodiment, the primary reactor emerges into a post-combustion chamber whereby the post-combustion gases are discharged from the post-combustion chamber through the suction tube passing through the primary reactor.

1 . A combustion device comprising a combustion chamber, a primary reactor and a gas suction and exhaust tube  4  in which the gas suction and exhaust tube  4  passes through the primary reactor. 
     
     
         2 . The combustion device as claimed in  claim 1 , in which the primary reactor terminates in a postcombustion chamber and in which the gas suction and exhaust tube  4  passing through the primary reactor removes the postcombustion gases from the postcombustion chamber. 
     
     
         3 . The combustion device as claimed in  claim 1 , in which the gas exhaust tube is concentric with the primary reactor. 
     
     
         4 . The combustion device as claimed in  claim 2 , in which the combustion chamber is a primary combustion chamber receiving the fuel and is connected to the postcombustion chamber by the primary reactor. 
     
     
         5 . The combustion device as claimed in one of the preceding claims, in which the burned gases are sucked out by venturi effect at the gas outlet  9 . 
     
     
         6 . The combustion device as claimed in one of the preceding claims, in which the exhaust tube is configured so that the burned gases are sucked independently by chimney effect once the combustion is initiated. 
     
     
         7 . The combustion device as claimed in one of the preceding claims, in which the primary reactor comprises first inlet slits through which the oxidizer is sucked in. 
     
     
         8 . The combustion device as claimed in one of the preceding claims, wherein it is provided with second slits placed around the primary reactor and through which the oxidizer makes contact with the fuel present in the combustion chamber. 
     
     
         9 . The combustion device as claimed in one of the preceding claims, in which the chamber is equipped with a tube for incoming products, made from refractory steel provided with a feed screw for products to be dried and/or requiring pyrolysis. 
     
     
         10 . The combustion device as claimed in one of the preceding claims, wherein it comprises fuel grinding means which comprise at least one tubular spindle passing through the chamber and are equipped with mixing means. 
     
     
         11 . The combustion device as claimed in one of the preceding claims, wherein it comprises an adjustable air inlet for air entering directly into the postcombustion chamber. 
     
     
         12 . The combustion device as claimed in one of the preceding claims, wherein it comprises a device for regulating the temperature of the postcombustion chamber by creating a void between the chamber itself and a thermal insulation surrounding it, and means for blowing fresh air into this void between the outer walls of the chamber and the inner wall of the thermal insulation.
