摘要:

随着近几年我国经济增速放缓,全年的总发电量逐年下降,全国火电机组年平均利用小时逐年减少,火电机组运行负荷常年处于较低水平,机组启停频繁。面对火电机组常年低负荷运行现状和国家环保的要求,实现电厂全负荷脱硝势在必行。针对国产600MW超临界燃煤机组全负荷脱硝改造进行技术路线分析,通过对比各改造技术路线的优缺点、改造工程费用等,推荐适合燃煤机组全负荷脱硝改造的指导技术路线。

Abstract:

With the economic growth of China slowed down, the total generation capacity and thermal power unit utilization rate is lowered year by year. The load of thermal power generation units maintains low level for constantly, and frequently start and stop. Due to the operating condition and environmental requirements, power plant variable load denitration is imperative. By analyzing and comparing kinds of 600MW supercritical coalfired unit variable denitration technical approaches, the most suitable approach for coalfired unit was recommended.
