32 THERMAL POWER PLANT Under Perform, Achieve and Trade 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)
The mill reject loss depends on the amount of pyrite in coal and the mill operating condition. The rejects by the mill do have a heat value which is accounted as mill reject loss. This can be minimized by properly maintaining the mill cleanaces and operating at the optimal condition. The carbonmonoxide loss is due to combustion not being fully ...
