Coal-fired power generation belongs to thermal power generation
Thermal power (thermoelectric power generation) refers to the utilization of thermal energy generated when Solid, liquid and gaseous fuels such as coal, oil and natural gas are burned for heating using thermal energy. Water transforms water into high temperature to produce high pressure water vapor, then the water vapor drives the generator to generate fuel chemical energy → Steam thermal energy → Mechanical energy → Electrical energy is simply there. use of fuel (coal) to generate heat. The water forms superheated steam at high temperature and high pressure, which drives the turbine, causing the generator rotor to rotate (electromagnetic field). The stator coil cuts the magnetic lines of force. and emits electrical energyeu. It then uses the step-up transformer to reach the system voltage, connects to the grid and transmits the electrical energy outside.
The heat released by the combustion of coal in the boiler heats the water into steam with a certain pressure and temperature. Then the steam enters the steam turbine along the pipe and continuously expands to do the work. steam turbine rotor and rotates at high speed. The steam turbine drives the generator to produce electricity. The steam that has finished its work in the turbine is discharged into the cooler and condenses into water, which is then sent to the deaerator by the condensate pump. The water is heated by the turbine extraction steam coming from the extraction pipe into the deaerator and the contained gas is finally amplified by the feed water pump and returned to the boiler to repeat the cycle process. -above. by the generator isamplified by the transformer then entered through the network. There are three types of energy conversion processes in thermal power generation: the chemical energy of coal is converted into thermal energy in the boiler; thermal energy is converted into mechanical energy in the steam turbine; the generator. The main power conversion equipment - boilers, steam turbines and generators - are called the three main hosts of thermal power plants, and the boiler is the most basic power conversion equipment among the three main hosts. .
