Abstract
A method of operating a pulverized coal furnace wherein the coal is introduced with minimal oxygen through an intermediate zone of the furnace which also has a relatively low oxygen content. The carbon particles are projected into an upstream portion of the furnace where secondary air is introduced to burn the carbon particles. The combustion products pass upwardly through the intermediate zone to a downstream zone where tertiary air is added to complete combustion.
