Quantity of standard coal = [Heat consumption rate - Calorific value of standard coal, kcal/kg, 29.3076 kJ/g
Calculate electricity production
The calorific value of a ton of coal Standard coal is 1,000 kg * 7,000 kcal. Now the coal consumption of the large-capacity power plant unit is low, which can reach 0.3 kilograms of electricity per kilowatt hour. The energy production of 1 kilogram of coal = 3.333 kilowatt hours of electricity. 1 ton of coal = 3333 kilowatt hours.
1 kilowatt hour of electricity = 860 kcal.
You need to know your main steam parameters. The average temperature and pressure range is relatively. wide, the water supply value, and the steam consumption rate of the steam turbine (different manufacturers have differences, imported?) Generally speaking, they are equivalent to those in the article. The grandeur evokedée is generally between 600 and 800g of standard coal.
General calculations are difficult. A simple calculation is to first calculate the Rankine cycle efficiency based on the steam parameters and multiply it by the turbine efficiency and generator efficiency. Then multiply the boiler efficiency and then calculate the coal consumption for electricity production through dimensional conversion.
Calculated based on 640 g of standard coal per kilowatt hour, equivalent to 1,000 kg*2,000 kcal/(7,000 kcal*0.64 g of standard coal)=446 kWh
