Development and Application Overview of Electrostatic Precipitation Technology for Coal-fired Power Plant in China
摘要
Abstract
The evolution of emission requirements and emission characteristics of dust from coal-fired power plants in China is described, the development history of electrostatic precipitation technology in coal-fired power plant is reviewed, the application of electrostatic precipitation technology is introduced, and its development trend is prospected. Since the independent research of electrostatic precipitation technology began in 1 960 s, China has already became one of the most dominating countries in the world after more than fifty years of development through the technology, digestion, absorption and re-innovation. The Ultra-low dust emission of coal-fired power plant and the main technology to fulfill the Ultra-low emission has attracted worldwide attention. The electrostatic precipitator has always been the main equipment for particle control in coal-fired power plants, which can meet the requirement of ultra-low emissionof 10 mg/m3or 5 mg/m3. As for the high ash coal (Aar>25%) unit, it is also possible and feasible to realize the concentration of particle emission lower than 5 mg/m3through cooperating with wet desulfurization and dust precipitation. It is expected that the direction of dust precipitation technology will be energy saving, cooperative control, intelligence, standardization and internationalization in the future.关键词
