The study of coal-fired power plant flue gas dust removal issue

Abstract With the development of economy, China's electricity demand is also rising year by year, with the task of coal-fired power plants is becoming more and more heavy, although the development of thermal power brought the ascension of the economy, but also brought negative impact, coal-fired power plants burning coal and so on has a huge smoke dust pollution, is one of the major source of PM2。5 air polluted, climate warming, haze is more and more serious, this problem is the deep concern of the government authority。 

Research of flue gas dust removal problem for environmental protection, building a green city has an important meaning, control the emissions of pollutants, control of PM2。5, can effectively reduce the smog problem。 This article introduces the various flue gas dust removal technology, and the analysis of the effect of new technology in the application of electrostatic precipitator。

There are 9 figures, 8 tables and 21 references in this paper。
