Abstract
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.
