Abstract 

Power boiler installations of thermal electric power plants (TPP) are among the main pollutants of the air basin of the environment.

The object of this study is the method to improve the environmental performance of the coal combustion process in TPP, which lies in supplying air with an increased oxygen content to the combustion zone.

The purpose of the article is the theoretical study of the application of the method of increasing the ecological indicators of the process of coal combustion in TP-100 boilers of the Burshtyn TPP, which is achieved by delivering pure oxygen to the prepared dust-air mixture directly to the burners. This article shows that it is possible to reduce the volume of combustion products by 30 thousand nm3/h and by 50% by concentration of nitrogen oxides for a power unit of 200 MW with a boiler TP-100 of the Burshtyn TPP with fuel consumption of 55-89 tons per hour.
