Abstract
A powdery fuel combustion apparatus disposed on furnace side plane ( ) of vertical square body type furnace in which a vertical plane passing through a fuel jetting directional axis ( ) does not cross the furnace side plane orthogonally, and thus the workability of furnace wall tubes and burner panel, and the maintainability of burner nozzle are improved. The apparatus includes a burner nozzle ( ) that is formed such that the nozzle has right and left non-symmetrical shapes, with respect to a vertical plane passing through axis ( ). Also, the nozzle has a tip portion opening lying in an opening plane ( ) which coincides or is parallel to the furnace side plane ( ).
