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.
