ABSTRACT:
Methods and apparatus for reducing pollutant emissions, and in particular, for reducing NO.sub.x and particulate emissions, from spreader-stoker-fired furnaces. A combustible material is introduced into the spreader-stoker-fired furnace and combusted while the stoichiometric ratio of oxygen to combustible material in different regions of the furnace is carefully controlled. Control of the stoichiometric ratio is accomplished by controlling the amount of air injected into different regions of the furnace and by controlling the amount of smaller particles of combustible material or fines introduced into the furnace.
