ABSTRACT
The invention provides a furnace burner that
operates with pulverized fuel. Heated combustion
air flows with a rotational movement along a burner
tube (9,119) and a slurry of pulverized fuel in
water is discharged into the air from nozzles (14,114).
The effect of the air, and the extended residence
time resulting from the rotation of the air, will
effect drying of the fuel before it reaches the
furnace opening (2,102).
