Abstract :
PPS filter is widely used in Coal-fired power plant flue gas dust collection, but the performance of PPS filter is influenced by the NO2 in the flue gas. In this paper, effect of NO2 on PPS filter was studied. Through the analysis of mechanical performance, microscopic characteristics and chemical structure of PPS filter, it is considered that NO2 has definite corrosive effect on the PPS filter, and corrosion increases with the increase of NO2 concentration and aging time. The temperature has accelerating effect on the corrosion.
