摘要
燃煤电厂不仅要控制SO2的排放,而且要控制NOx的排放。介绍了选择性催化还原法(SCR)脱硝技术,并结合其在大唐哈尔滨第一热电厂2台300 MW机组的应用情况,对SCR烟气脱硝技术的化学反应机理、工艺流程、主要设备及实际运行情况进行了介绍。
As we know,SO2 and NOx emission should be strictly controlled in coal-fired power plants.An introduction is being presented to the selective catalytic reduction（SCR） denitrification technology applied in Datang Harbin No.1 Thermal Power Plant.Based on actual application of the SCR technology to its 2×300 MW power units,the chemical reaction mechanism,working process,main equipment involved and actual operation conditions of the SCR flue gas denitrification technology are described.
