Abstract (en)
[origin: EP0313469A1] Burner arranged transversely in a pipe to heat an oxidant gas (air) circulating at high speed in this pipe, and consisting of a tube (10) supplied with fuel gas and pierced with holes, which are possibly provided with injectors, making it possible to emit jets of gas directed downstream, and a flame stabiliser (12) comprising two diverging wings forming a deflector and delimiting a zone which is sheltered from the flow of gas to be heated. <??>In order to maintain a practically constant aeration rate of the air/fuel mixture in spite of the variations of the flow of fuel and/or of the speed of the gases to be heated, the burner comprises, downstream of each hole (14) and coaxially therewith, a converging/diverging nozzle (26) arranged in such a manner that the jet of gas emerging from said hole creates a low pressure at the entrance of the nozzle, and the entrance of the nozzle is made to communicate with the internal space of said pipe surrounding the burner by at least one opening (24) arranged so as to eliminate the influence of the dynamic pressure of gas to be heated on the flow of gas drawn in by the nozzle through said opening. <IMAGE>
