| 摘要 |
The present invention relates to a burner module in an air stream (1) comprising a feed pipe (2) of substantially circular cross section and having an axis, fuel injection orifices (20) situated on the pipe and intended to produce a flame, oxidant injection orifices (34) and fins (3) arranged symmetrically with respect to a plane P of flow of the fuel upstream of the burner module and laterally on the pipe (2) on each side of the fuel injection orifices (20); it is characterized in that there are at least two fuel injection orifices (20) in a section of the pipe (2) and that these have an axis that makes an angle α with the plane of flow P of the oxidant. In this way, gas is injected at several orifices situated in at least two divergent planes. These two planes delimit a space to which fuel is not supplied and to which oxidant is not supplied, thereby encouraging internal recirculation of the combustion gases within the flame and bringing a large proportion of the burnt gases back toward the centre. |
