摘要
针对当前最为成熟且应用最多的选择性催化还原(SCR)脱硝技术在燃煤电站启停炉或低负荷运行时无法投运或出力不足的现状,介绍了一些研究较多的湿法烟气脱硝技术,包括湿式络合吸收法、碱液吸收法、酸吸收法、氧化吸收法、液相还原吸收法,分析了各项技术的优缺点,并为湿法烟气脱硝技术的发展方向提出了建议。
Selective catalytic reduction （SCR） technology is the most mature and widely used flue gas denitrifi- cation technology in coal -fired power plants. However, SCR system would be unable to put into operation or output sufficiently during boiler start - stop process or low - load operation. According to this situation, wet flue gas denitra- tion technology, including the wet complex absorption method, the alkali absorption method, the acid absorption meth- od, the oxidation absorption method, and the liquid phase absorption reduction method, were introduced. The advan- tages and disadvantages of each technology were analyzed, and some suggestions were put forward for the development direction of wet flue gas denitration technology.
