Currently, the production processes of several large power plants are as follows:
1. Thermal power plant
Boiler: chemical energy of the fuel → thermal energy of the combustion gases → thermal energy of the steam
p>Steam turbine: thermal energy of the steam → mechanical energy< /p>
Generator: mechanical energy → electrical energy
The overall production process: fuel chemical energy → thermal energy → mechanical energy → electrical energy
2. Hydroelectric Power Plant
The basic process of energy conversion in a hydroelectric power plant is: water energy → mechanical energy → electrical energy
3. Nuclear power plant
Nuclear power plant The basic process of energy conversion: atomic energy → thermal energy → mechanical energy → electrical energy
4.
The operating principle of the wind turbine is relatively simple. The tower wind wheelnot under the action of the wind. Convert the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates, driven by the wind turbine shaft, to produce electricity.
