The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal. The formula for calculation of increase in energy consumption of Mills as a result of change in coal quality is mentioned below. Operating Hours (hrs) Gross Generation (Million Units)X 1000/Operating load (MW) Total Coal Consumption per unit (AY and BY) (Tonnes/Hr) (GHR X Operating Load)/ Coal GCV Where GHR Gross Heat Rate (kcal/kWh)

coal mill an overview sciencedirect topics

All mill capacities are based on a standard coal with HGI 50. The larger the value for HGI, the easier it is to grind the coal, resulting in a higher mill capacity. An HGI of 35 reduces the mill capacity about 20%. Coals with HGI less than 35 can be pulverized, but mill capacities are reduced significantly. Mill Capacity Calculations. There are a large number of formulae for the calculation of the capacity of a milling tandem. Hugot gives the following formula A 0.9 cnN(1-0.06nD)LD 2 /f. where c. is a factor dependent on the cane preparation equipment, c
