Chemical energy of fuel → Thermal energy of steam → Mechanical energy → Electrical energy. In simple terms, it uses fuel to generate heat and heat water to form superheated steam at high temperature and high pressure, which drives the rotation of the gas turbine, drives the rotation of the generator rotor ( electromagnetic field) and the stator coil. Cut off the magnetic lines to output electrical energy, then use the step-up transformer to increase the system voltage, connect it to the grid and transmit it. electrical energy to the outside.
Then the steam enters the steam turbine along the pipe and continuously expands to do the work. It impacts the rotor of the steam turbine and rotates at high speed. The steam turbine drives the generator to produce electricity. Finally, it is further amplified by the water supply pumpand returned to the boiler to repeat the above cycle process. The electricity generated by the generator is amplified by the transformer and then injected into the electrical network. There are three types of energy conversion processes in thermal power generation:
