摘要

A thermal enclosure (1) is equipped with at least one burner (2) partially engaged in one of the walls (6) of the said enclosure. The burner comprises an oxidant and fuel supply pipe (7) formed by a central fuel inlet duct and an annular oxidant inlet duct and a body (4) on which the pipe (7) is fixed. The oxidant and the so-called primary fuel are injected at high speed and the body (4) includes a combustion chamber (20) aligned with the pipe (7), means (23) for increasing the speed of the jet formed by the products leaving the combustion, at the opposite end of the said chamber (20), means for supply of a secondary fuel and means (30) for distributing the injection of the secondary fuel into the jet.
