    摘要： The present invention relates to a burner (1) that comprises a conduit for primary air or gas delimited by an outer wall and a concentric inner wall of axis X and conduits (21) for injecting radial primary air or gas, said burner being characterised in that the air or gas conduit (22) comprises a ring (3) rotatably mobile and having axial protrusions constituting distributors (30) that engage with the radial primary air conduits (21) disposed on the inner wall and form two channels (210, 211) of different angles in each conduit (21). The rotation of the ring (3) makes it possible to vary the injection angle of the radial primary air. Therefore, the adjustment is located just at the end of the burner (1), at the outlet of primary air into the furnace, by modifying the outlet angle of the radial component having a fixed cross-section, which greatly simplifies the adjustment of the burner (1). This avoids bringing into rotation mobile parts that are in direct contact with the outside of the burner and therefore subject to very high thermal stress with a risk of damage to said parts.

    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.

    摘要： The method of the invention comprises a premix burner formed by a group of premix nozzles (2) disposed in a circle of diameter DB around a central nozzle (4) disposed on a central axis A of the burner (1) and intended to create a radial flame (5), characterised in that the oxidizer-to-fuel ratio (R) of the group of nozzles (2, 4) is between 1.3 and 1.75. The radial flame (5) is used for the cross-lighting of the different premix nozzles (2, 4). An annular flame is also provided by premixed combustion in order to keep the ratio (R) favourable to the low production of thermal nitrogen oxides at the intersection of the radial flame and the flames from the nozzles.
