The overall energy conversion in a coal-fired power plant is a complex process that involves the conversion of chemical, thermal, mechanical and electrical energy. The following are the basic steps of the process:
1. Conversion of chemical energy to thermal energy: This process takes place in the boiler of a coal-fired power plant. Here, coal is burnt, releasing a large amount of heat energy. The chemical energy in the coal is thus converted into thermal energy. 2.
2. Conversion of thermal energy into mechanical energy: The conversion takes place in a steam turbine. The high-temperature, high-pressure steam produced in the boiler is fed into the steam turbine, which pushes the blades of the turbine to rotate, thus converting thermal energy into mechanical energy. 3.
3. Conversion of mechanical energy to electrical energy: The final step occurs in the generator. The rotation of the steam turbine drives the rotor of the generator to rotate, which in turn generates an electric current in the stator of the generator, converting mechanical energy into electrical energy.
In summary, the overall energy conversion process in a coal-fired power plant is the conversion of the chemical energy in the coal to thermal energy through combustion, and then the conversion of the thermal energy to mechanical energy and ultimately to electrical energy through the steam turbine and generator. There is a certain amount of energy loss in this process, so power plants take various measures to improve energy conversion efficiency and reduce energy loss.
