Technical Evaluation of the Selection of Flue Gas Purifying Device of Power Plant

Abstract:

The paper introduced several ash separator, desulfurization devices and denitrification devices which were widespread used in thermal power plant in recent years and respectively compared the technicality efficiency of them. It comes to the conclusion that: in the choice of ash separators, bag filter which has more merits than ESP, it has the advantages of reliable operation, simple maintenance, adapting to change in different coal and higher efficiency. In the choice of desulfurization technology, wet limestone-gypsum desulfurization technology is the most mature, which has stable operation and wide adaptability. Therefore, the thermal power plant prefer to it. In the choice of denitrification devices, SCR with low NH3 escape rate and easy to maintain, so it has become the mature and mainstream technology at home and abroad.
