Based on the average energy consumption level of domestic power plants, it generally takes about 300 grams of pulverized coal to produce 1 kilowatt hour of electricity.
Different types of coal have different carbon contents, and the amount of carbon dioxide removed is also different. The carbon content of coal is approximately 20-70%. Typically, power plants use lean coal, bituminous coal and lignite, with a carbon content of around 55%. There are about 165 grams of carbon in 300 grams of coal, which will generate about 500 grams of carbon dioxide. Of course, this is generated when the coal is completely burned, and this is only a qualitative value.

I hope this helps you.
How much coal does a 1 million kilowatt thermal power plant use per year?
Circulating water in thermal power plants is divided into open cycle and closed cycle. consumption is very low. Your factory should It's an open cycle. The amount of circulating water extracted is related to the operating time of the unit. Currently, the annual operating time of the power plant is only about 5,500 hours, so it is more reliable to calculate the water consumption at 5,500 hours.
It depends on the amount of energy generated. Coal consumption is generally calculated based on an hour of use 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 can only give a rough range of coal consumption here, as the efficiency of production units varies considerably.ent. If it is an ultra-supercritical unit, it will consume less coal, while a subcritical unit will consume more. coal.
