ABSTRACT:
A process for reducing sulfur emissions and increasing particulate removal in the combustion of pulverized coal is presented. Pulverized sulfur-containing coal is injected along with combustion air into a combustion chamber and fired to create a combustion zone within the chamber, thereby creating gaseous sulfur and particulate emission products. The emission products are directed to an exhaust means where the particulate emission products are removed. A fuel having negligible sulfur content and a heating value higher than coal is injected in substantially the same direction as the coal and combustion air stream into a region of the combustion zone through which a majority of the of the gaseous sulfur emissions must pass to reach the exhaust means, thus increasing the temperature of the region in an amount sufficient to increase the sulfur content of the particulate emission products.
