There are several ways to generate electricity in power plants-what are their respective processes?

At present, the production processes of several major power plants are as follows:

1. Thermal power plant

Boiler: chemical energy of fuel → flue gas heat energy → steam heat energy.

Steam turbine: steam heat energy → mechanical energy

Generator: mechanical energy → electric energy

Total production process: chemical energy of fuel → thermal energy → mechanical energy → electrical energy.

2. Hydroelectric power plant

The basic process of energy conversion in hydropower plants is: water energy → mechanical energy → electric energy.

3. Nuclear power plant

The basic process of energy conversion in nuclear power plants: atomic energy → thermal energy → mechanical energy → electrical energy.

4. Wind power plants

The working principle of wind turbine is relatively simple. The wind wheel rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator is driven by the wind wheel shaft to rotate and generate electricity.
