Abstract

Abstract: The operation state of the combustion system and the reasons of occurred problems before the combustion system reformation were analyzed. Aiming at the situation of the coal market, which supplies much inferior coal and much coal kinds, the combustion system of the boiler was reformed, and better effects were obtained. The target, which is to fire the blending much inferior coal and there is not serious coking to form on the water wall and the platen superheater heating surface of the boiler, was realized. The safe and stable operation of the combustion system was ensured, and the overall economic performance of the boiler was improved.

Key words: pulverized coal-fired boiler, stable operation, coal blending, inferior coal, technical reformation
