You may not know that the coal burning in a thermal power plant is so dusty!

The thermal power plant is referred to as a thermal power plant. It is a factory that uses coal, oil, and natural gas as fuel to produce electric energy. Its basic production process is: fuel burns heated water in a boiler to generate steam, converts chemical energy of fuel into heat, and steam pressure pushes The turbine rotates and the thermal energy is converted into mechanical energy. Then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy. For coal-fired power plants, the unloading, conveying and storage process of raw coal is the main source of dust. To prevent the generation and spread of dust, the Zhongshan Thermal Power Project uses a fully enclosed continuous screw unloader to unload coal. The continuous screw unloader is The high productivity and utilization factor make it easy to realize the automatic transportation of materials. At the same time, because it is closed transportation, the pollution to the environment is small. Therefore, the wide application of the screw unloader is of great significance for energy conservation and environmental protection, and can effectively achieve no coal. The particles fall and dust, environmentally friendly and efficient.

The Zhongshan Thermal Power Project uses a fully enclosed coal-bearing trestle and a fully enclosed circular coal yard for coal storage to maximize the control of dust diffusion to the surrounding area and meet environmental requirements. It is transported from the coal yard to the coal hopper by a coal conveyor belt. In order to improve coal-fired efficiency, thermal power plants are all burning pulverized coal. Therefore, the raw coal in the coal hopper should be sent to the coal mill for grinding into pulverized coal. The ground pulverized coal is carried by hot air and sent to the boiler through the powder discharging fan. Burning in the hearth. The hot flue gas formed after the combustion of pulverized coal flows along the horizontal flue and the tail flue of the boiler, releasing heat, and finally entering the dust remover to separate the burned coal ash, and the clean flue gas passes through the chimney under the action of the induced draft fan. Discharge into the atmosphere.
