Abstract of the Disclosure A tangentially fired pulverized coal furnace in which the means for introducing fuel and air from the corners operate as independ- ent firing systems at low ratings and contribute to the fireball at higher ratings. The coal flow through a nozzle is deflected radially outwardly at low ratings and allowed to continue essentially straight at high ratings. A surrounding secondary air flow is concentrated at the coal stream and may be varied from a swirling action at low ratings to a parallel flow action at high ratings.
