Coal trader’s web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr; A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.
With lower furnace pressure drop, the power consumption of air fans can be reduced, whereas the comminution energy consumption of coal particles will be increased. To optimize the auxiliary power consumption, the balance point between the power consumption of air fans and that of the coal comminution should be investigated.
