Process of electricity production in a thermal power plant:
1. Transport the fuel to the power plant. After transportation and processing, it is sent to the boiler for combustion.
2. The chemical energy contained in the fuel is converted into thermal energy and transferred to the boiler water, transforming the water into steam at high temperature and high pressure.
3. Superheated steam with higher pressure and temperature is sent to the steam turbine through the pipeline, causing the steam turbine to rotate to do the work , the temperature of the steam is quickly reduced, and finally discharged into the condenser. In this process, the thermal energy of the steam is converted into the mechanical energy of rotation of the turbine rotor.
4. The mechanical energy of the turbine rotor is converted into electrical energy via the generator.
5. The electrical energy generated by the generator is sent to the transmission line through the step-up transformer to supply to users.
The above represents the entire process of producing electricity in a thermal power plant.
