distribution of outlet temperature is caused by milled fuel type. During periods of coal and biomass comilling, the mill outlet temperature demand has been set at 115 C. If the mill was gridding, only coal mill outlet temperature demand has been set at 105 C. Histograms are presented in Figures 2 and 3.

The four most common coal pulverizers types are: BallTube Mills This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills

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%.
