燃煤电厂“有色烟羽”控制技术研究及工程应用

Research and Engineering Application of "non Ferrous Plume" Control Technology in Coal-fired Power Plant

燃煤电厂在对烟气实施了脱硝、除尘、脱硫等一系列减排措施后,大幅降低了颗粒物以及SO2和NOx等污染物的排放,但部分电厂烟囱出现的"有色烟羽"现象。本文结合河北某2×330MW燃煤机组"有色烟羽"现象的分析,采用低低温电除尘器及烟气冷凝再热技术等组合技术进行"有色烟羽"治理改造,并取得显著效果。

After a series of emission reduction measures, such as denitri fication, dust removal and desulfurization, have been implemented in the flue gas of coal-fired power plants, the emission of particulate matter, SO2, NOx and other pollutants has been greatly reduced, but the "non-ferrous plume" phenomenon appears in the chimneys of some power plants. Based on the analysis of "non- ferrous plume" phenomenon of a 2 × 330MW coal- fired unit in Hebei Province, the combined technology of low-temperature electrostatic precipitator and flue gas condensation reheat technology is adopted for the treatment and transformation of "non-ferrous plume". And achieved remarkable results.
