For good pulveriser and combustion performance, the temperature of the coal air mixture leaving the mill should be maintained as high as possible within the safe temperature limit of the particular coal. A temperature of 85 to 90ºC is acceptable for coals with normal VM. An outlet temp. below 60ºC may not dry the coal sufficiently.

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%.
