Background

A thermal power plant is a thermal power plant for short, and is a plant for producing electric energy by using combustible materials (such as coal) as fuel. The basic production process is as follows: the fuel heats water to generate steam when being combusted, chemical energy of the fuel is converted into heat energy, steam pressure pushes the steam turbine to rotate, the heat energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, so that the mechanical energy is converted into electric energy. Modern thermal power plants are large and complex plants for producing electric and thermal energy, which consist of the following 5 systems: (1) a fuel system. (2) A combustion system. (3) And (5) a steam-water system. (4) An electrical system. (5) And a control system. In the above system, the most important equipment is a boiler, a turbine and a generator, which are installed in a main plant of a power plant, and the basic production process of the thermal power plant is that fuel is burned in the boiler to release heat thereof and transfer the heat to water in the boiler, so that high-temperature and high-pressure steam is generated, and a great amount of carbon dioxide is contained in flue gas discharged from the thermal power plant.
