Development of Mill-burner System for Low-rank Coal with

pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. The evaporation of water in raw coal increases the vapor concentration in the gas at the mill outlet and consequently the O2 level of the primary gas in the burner is expected to be decreased to approximately 9%. The new system therefore involves operation under
