Abstract

Abstract: To achieve the goal of ultra-low emission for coal-fired power plants, based on the conventional EFIP technology, the ultra-clean electrostatic-fabric integrated precipitator(EFIP) is developed, by upgrading the key technologies such as coupling matching between electrostatic field and fabric area, high uniform flow field distribution, high-precision filtration and particle coalescence technology. Featured by stable long-term emissions, simple technical process, high adaptability to varieties of coal, low investments, less land occupation, low maintenance costs and no waste water production, the ultra-clean EFIP technology has been rapidly popularized and widely used in coal-fired power plant ultra-low emission projects for the recent couple of years, with the total installed capacity of domestic coal-fired power plants over 30 000 MW, including eight 1 000-MW units. The emission concentrations are all below 10 mg/m³ or 5 mg/m³, and the average running resistance is around 663 Pa. The ultra-clean EFIP has become one of the mainstream technical routes to achieve ultra-low emission for coal-fired power plants, and will play an even more important role in the ultra-clean emission renovation projects for power plants burning inferior coals in western area of China.

Key words: coal-fired unit, ultra-low emission, ultra-clean electrostatic-fabric integrated precipitator, precipitator, electrostatic-fabric integrated precipitating
