Abstract
A coal burner with impeller for a furnace has a housing containing a plurality of sets of blades which direct the fuel from the coal nozzle into a plurality of non-intersecting flows directed obliquely towards the longitudinal axis of the housing. The non-intersecting flows create a fuel-rich devolatilization zone and an air-rich char burnout zone within the furnace and limit the flame length of the burner.
