烟气换热器及其在燃煤电厂烟气治理中的作用

Flue Gas Heater and It's Function in the Flue Gas Control for Coal-fired Power Plant

本文简单介绍了烟气换热器的主要型式、布置方式及布置烟气换热器的典型烟气污染物控制技术路线。以低低温电除尘为核心的烟气协同治理技术路线中,烟气换热器中烟温降低对颗粒团聚的促进作用,配合电除尘器及湿法脱硫,可经济高效的实现燃煤电厂的烟尘超低排放,具有较好的应用前景。

In this paper, the main type of flue gas heat exchanger, arrangement and the arrangement of the typical flue gas pollution control technology for flue gas heater was simply introduced. In the technical route with the LL - ESP as key, temperature lowering in flue gas heat exchanger can improve the particles coagulation, cooperate with ESP and WFGD, flue gas ultra - low emissions of coal - fired power plants can be reach easily and efficiently,which has good application prospect.
