摘要
随着国家环保指标的不断收紧和核电项目的大量建成投运,国内火电厂一方面承受着排放指标的压力,另一方面面临着机组长时处于低负荷运行的现实,因此对目前投运较多的SCR脱硝设备进行升级改造,保证低负荷下的脱硝投运,以进一步降低机组NOx排放量势在必行。对国内外广泛关注的几个改造方案优缺点进行分析,期望为国内电厂的SCR升级改造提供一定参考。
With the tighten of national environmental indicators and the establishment of a large number of nuclear power plants ,the thermal power plant are facing the pressure of the environment protection and longtime low load conditions, Upgrading and reconstruction of the SCR De-NOx equipment are necessary,the transformation can improve the operation rate in low load conditions. Advantages and disadvantages of transformation schemes focused at home and abroad are analyzed, and hope to provide certain reference for the SCR upgraded.
