Abstract: Abstract:The features of the east Junggar coal include the low price, the high volatiles, the high caloric value and the low ash fusion point. To fire the east Junggar coal may cause serious coking in boiler and threaten safe operation of the boiler directly. In the Owned Power Plant of Xinjiang Xinte Energy Company Limited, the scientific theory was combined with practical experiences to direct the blending combustion of the east Junggar coal, and some anticoking measures were adopted. The flue gas temperature in the furnace outlet was reduced effectively, the boiler coking was lightened, and the safe operation of the boiler was ensured.

Key words: Keywords:east Junggar coal, blending combustion, furnace temperature, coking
