Abstract: In this paper we review the development of Chinese Electrostatic Precipitator (ESP) in the passed 20 years, introduce the recent situation of our country's ESP technology and forecast the development prospect of ESP in China. Keywords: Electrostatic Precipitator, ESP technology, technology development, technology progress Table 1 Production and management situations of 13 key enterprises in recent years Industrial Sales Export Increase Output Income Value Year Amplitude (10000 (10000 (10000 (%) yuan) yuan) yuan) 2000 182086 139215 5652 2001 213017 175165 4686 25.82 2002 287098 214693 7745 22.57 2003 335288 283102 7825 22.54 2004 428246 392698 11310 27.88 2005 638600 502166 15710.2 27.22 2006 764290.4 574358 60661 14.38 2007 1214291.9 730137 83720 27.12 In a conclusion, ESP in our country has a late beginning but rapid development. National economy has developed rapidly since the reform and open-door policy being carried out, which provides broad market for the application of ESP. By the end of the last century, our country has become a great ESP power in the world. China has a large ESP production and using amount. ESP made in China not only meets the domestic requirement, but also be exported to decades of countries. Now the ESP industry has become one of competitive industries in Chinese environmental protection industry. ESP applied in power plant is the most important part. Only several power plants used ESP before 1980. Quantity of ESP applied in power plant increased constantly from mid 1980s. Electric power industry became the biggest user of ESP after 1990. ESP quantity applied in power plant makes up 75% of total ESP quantity in China. From 1990 to 2000, dust emitted from power plant was kept below 4000000 ton while total thermal power units increased from 76011 MW to 220000 MW. ESP toke an important role in power plant dust treatment. ESP applied in power plant in our country has a late beginning. The first ESP matching 300000 WK unit was set in Jiangsu Jianbi power plant in 1983; the first ESP matching 600000 WK unit was set in Anhui Pingyu power plant in 1989; the first ESP matching 900000 WK unit was set in Shanghai Waigaoqiao power plant in 2001; the first ESP matching 1000000 WK
