Detection of Malfunctions and Abnormal Working .

2. The coal mill The work presented in this chapter is based on a MKM-33 ball mill used at Rybnik Unit 4 (rated capacity 220 MW). The mill is one of six mills supplying the 650-k (steam production of 650 t/h) boiler. However, the proposed method in this chapter is so generic that it can be applied to other types of coal mills.

How to Calculate the Coal Quantity Used in a Power Plant

Oct 15, 2009· 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.
