Description

Technical Field

[0002] Thermal power plants, also known as thermal power plants for short, are plants that use combustibles as fuel to produce electricity. The basic production process is: when the fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the steam turbine to rotate, converting the thermal energy into mechanical energy. The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. The prime mover is usually a steam engine or a gas turbine. In some smaller power stations, internal combustion engines may also be used. They all generate electricity by using the pressure drop in the process of high-temperature, high-pressure steam or gas passing through a turbine to become low-pressure air or condensed water.
