Abstract
This invention relates to a burner with low emission of polluting gases, comprising, in a conduit, an injector of fluid fuel which creates in the conduit, supplied with combustion-supporting air heated in an exchanger, a fuel/air mixture. The latter burns, creating a flame which clings to a stabilizer constituted for example by a hollow piece, of V-section, obturating a central part of the cross-section of the conduit. Downstream of this stabilizer there is placed an obstacle causing a local reduction follwed by a sudden increase in the cross-section of the conduit in order to promote oxidation of the carbon monoxide.
Claims11
Burner with a low emission of polluting gases, comprising:
- a straight conduit well which is made of refractory insulating material,
- an injector of fluid fuel which is supplied with combustion-supporting air and injects, in said conduit, a fuel/air mixture which burns, creating a flame,
- a flame stabilizer disposed in said conduit and formed by a piece made of refractory material, which obturates a central part of the cross-section of said conduit and is adapted to create a zone of recirculation,
- and an obstacle made of insulating refractory material, which is placed on the inner face of the wall of the conduit and causes a local reduction followed by a sudden increase of the cross-section of said conduit.
