摘要
本文针对新疆某火电厂2×300MW机组在低负荷工况运行时出现氮氧化物排放超标的情况,对该项目进行了全工况脱硝工艺改造,通过增设旁路烟道、挡板门改造和将全工况脱硝系统接入DCS系统改造后,使该火电厂机组氮氧化物的排放达到环境保护要求,为同类火电厂机组全工况脱硝改造工程提供应用参考。
Based on a certain power plant 2 × 300 mw unit in Xinjiang excess nitrogen oxide emissions during low load operation,the project for the full process denitration technology transformation,by adding a bypass duct,damper and the full process denitration system connected to the DCS system after modification,such as to make the power plant unit nitrogen oxide emissions meet environmental protection requirements,for the similar thermal power plants unit full process denitration project application reference.
