In this paper,the layout strategies of the 3 kinds of wet electrostatic precipitators,the integrated,horizontal and vertical,are studied from the field condition,investment,energy consumption,flue gas resistance,measuring point requirements and other aspects. Each kind of wet electrostatic precipitator has its own advantages and disadvantages and so it is recommended that the power plant make the third party organizations to carry out comprehensive economic and technical analysis according to their own actu...
