Abstract:

Abstract:To realize “near zero emission”,Guangdong Zhuhai Jinwan Power Plant Company Limited’s No.3 and No.4 unit took reconstruction. This paper introduced the reconstruction of desulfurization system,adding wet ESP(electrical precipitator),classification of economizer,denitration system adding catalyst,combination of duct fan and booster fan. After reconstruction,the emission concentration of dust,SO2 and NOx is lower than gas turbine unit, “near zero” emission was realized.

Key words: Keywords:near zero emission, gas dust, SO2, NOx, wet electric precipitator, desulfurization, denitration, economizer classification
