BURNER WITH PERIPHERAL INJECTION POINTS FOR AN AXIAL AIR FLOW

摘要

The invention relates to a burner(l), comprising two peripheral air supply ducts (6, 7), representing between 5 and 15% of the introduced air,one (6) of which comprises means (8) conferring a tangential component on the exiting air, the other duct (7) enclosing all other ducts (2, 4, 5, 6) on the burner (1) being designed such that the exiting air has an axial flow. According to the invention, the opening (14) for the axial air supply duct (7) is formed by a series of injection points (14) of fixed section, each having an angular extent comprising between a third and a tenth of the angle between two adjacent injection points (14),
