Abstract:

With the improvement of the environmental emission index, the original environmental protection facilities of thermal  power plants have been unable to meet the requirement of new pollutant emission limits. Retrofitting on power supply and power distribution system has to made for environmental protection facilities, in which the power supply connection scheme for the simultaneous removal of multipollutant system(SRS) becomes the main research area. Through the comparison and analysis on power supply scheme for SRS and the retrofitting scheme for desulfurization system,a reasonable technical scheme was given.
