Engineering Application of Flue Gas Ultra-Low Emission Technical Routes in Coal-Fired Power Plant

The atmospheric pollution situation in China is still serious. Flue gas emission policies are stricter and new technique is asked for market demand. In accordance with this present situation and to meet the requirement of flue gas ultra-low emission in Chinese coal-fired power plant, flue gas co-governance route with low-low temperature ESP technology as core task and WESP technical route could be used respectively. These two technical routes were described briefly. Typical cases from aspects of technical route, design requirement, technical proposal, operation effect and so on were introduced. Comparison of technical characteristics of two technical routes was conducted in this paper, and noteworthy problems and suggestions for flue gas ultra-low emission technical were pointed out. This paper could provide some reference for the selection of flue gas ultra-low emission technical routes and engineering promotion.
