Abstract

Abstract: Due to the asreceived coal grade was reduced and the sundries in raw coal was increased, the directfired system of 1025t/h boiler of Shengli Power Plant was often blocked, and this caused the combustion of boiler to be not stable and the combustible matter in flyash to be increased. The blockage reason of the directfired system was analyzed, and an improvement scheme was determined and implemented. Then, the safety, stable and economical operation of the boiler was ensured.

Key words: coal grade, classifier, blockage, combustible matter in fly-ash
