8%. According to relevant information on thermal power plants, the internal efficiency rate of thermal power plants is 8%. A thermal power plant, called a thermal power plant, is a factory that uses combustibles as fuel to produce electrical energy. Its basic production process is as follows: When fuel is burned, water is heated to generate steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure causes the steam turbine to rotate and the thermal energy is converted into mechanical energy. Then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy.
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 contentscarbon dioxide levels are different, 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 generates about 500 grams of carbon dioxide. Of course, this is generated when the coal is completely burned and only constitutes a qualitative value.
