Experiences in Power Plants

Due to the improvement of environmental protection standards, the electrostatic precipitator which used to occupy an absolute position in the power industry is being replaced by the bag precipitator step by step. Dust removal equipment used in power plants is usually used to purify the smoke in the tail gas and neutralize the harmful acid gas in the flue gas. Through the surface of the filter bag, all the harmful substances contained in the combustion residue and additives are separated. Because of the high combustion temperature and complex chemical composition, it is particularly important to choose the appropriate filter material. Many years of industry experience and successful cases have proved the outstanding contribution of Wuxi Guoju in the industry, showing advantages in terms of service life, ultra-low emission and higher cost performance.
