Based on the current common coal consumption value of 300 MW units from 320 to 340 g/kWh, the daily coal consumption is equal to 320*1081*10000/1000000=3459.2t. The maximum range should be 3,300 to 3,600 tons/day.
However, the daily electricity production of a power plant with an installed capacity of 1,200 MW is only 10 810 MW. This utilization rate is too low and coal consumption will be reduced. will certainly not be low, so actual coal consumption will only be high or low.
It depends on the amount of energy generated. The calculation of coal consumption is generally based on a usage time of 5,500 hours. In this case, a 1 million kilowatt thermal power plant uses approximately 1.5 to 1.8 million tons of standard coal per year. Standard coal refers to coal with a low calorific value of 7,000 kcal/kg.
We cannotWe will only give an approximate range of coal consumption here, as the efficiency of production units varies considerably. If it is an ultra-supercritical unit, it will consume less coal, while a subcritical unit will consume more. coal.
