The power plant precipitator is an important and necessary equipment. It is designed to eliminate airborne pollution caused by removing particulate matter from the exhaust gas of industrial processes, especially in power stations. The precipitator is a high-tech device working on the principle of electrostatic precipitation. Particles are charged electrically and made to stick to metal plates. Precipitator main are capturing fly ash, to improve air quality, and reduce the environmental impact of industrial process. The function of fly ash precipitator is to capture ash from the air caused by burning. It can also serve as a means for improving environmental quality and decreasing pollution generated when businesses carry on business activities. Its technology features include strongly construction engineering which can bear high temperatures efficiently. It operates a power supply system for particle charging that is capable of fully charging the largest particles. Also in place are automatic controls which can optimize performance. The technology can be applied far and wide to reduce the environmental impact from industrial work. It can be found in coal-fired power stations, cement plants, and metal smelting facilities. If we rely on this super clarification technique, the modern industrial setting shows that its life depends only upon its technology.
