75 tons of coal-fired steam boiler coal consumption:

First of all, look at the burning of coal, different coal, its combustion efficiency is different, the natural consumption of coal is also different, it can not be calculated according to standard coal, there will be a big error. The calorific value of inferior coal is between 18000KJ/kg---23000KJ/kg.
The coal consumption of a 75-ton coal-fired steam boiler can be derived from a formula that reads: Boiler coal consumption = boiler power * 3600 / coal combustion heat / boiler efficiency.
Calculated on the basis of a low-grade coal calorific value of 4000 and a boiler efficiency of 85%, the coal consumption of a 75-ton coal-fired steam boiler is 1.25*3600/4000/0.85=1.323 tons.

75 tons of coal-fired steam boiler operating costs:

1. Fuel cost: The coal consumption per ton of steam is 0.2 tons, the unit price of coal is 400 yuan/ton, and the total cost is 80 yuan; the fuel cost for a 75-ton coal-fired steam boiler for one year is: 80*75*8*360=172.8 Ten thousand yuan. Approx. USD 271,933

2. Electricity cost: The consumption is 9.6Kwh, the price of electricity is 0.58 yuan/kWh, the total cost is 42 yuan, and the cost of electricity consumption for a 75-ton coal-fired steam boiler is 42*8*360=1.2 million yuan. Approx. USD 1888

3, ash processing costs: 30,000 yuan / year; about US $ 4721

4, environmental protection fees: 100,000 / year; about $ 15736

5. Labor costs: 6 people, 20,000 yuan/person. Approx. USD 3147

Total Total: The operating cost for a 75-ton coal-fired steam boiler is: 1.728 million + 12,000 + 30,000 + 100,000 + 120,000 = 1.99 million. Approx. USD 313163
