This patent describes a method of firing a steam generator having a pulverized coal-fired furnace. This method consists of: 1.) introducing into the furnace a stream of pulverized coal entrained in primary air along a substantially horizontal longitudinal axis; 2.) introducing into the furnace, an independent stream of auxiliary air along an axis substantially parallel to the longitudinal axis; and 3.) impinging a first stream of working fluid against the pulverized coal and the primary air stream at substantially ninety degrees to it. This then deflects the pulverized coal and primary air stream away from the longitudinal axis as the pulverized coal and primary air is introduced into the furnace.
