Abstract (en)
[origin: EP0145382A2] The invention provides a burner that may be mounted at the wall (2) of a furnace. A mixture of pulverised fuel and primary air is discharged through a duct (4) and secondary air is discharged through a duct (8). The duct (8) includes a portion (16) that is convergent in the direction of flow. The convergent portion (16) houses a unit in the form of two concentric rings (22) and (23) between which are connected swirl inducing vanes (21). The unit can be moved between a forward position in which secondary air can pass only between the vanes and a retracted position in which part of the secondary air can flow between the vanes and part can flow as an envelope around the unit.
