摘要
经济增长带来的能源消耗使得火电厂排放了越来越多的氮氧化物,国家对环保的重视出台了更为严格的大气污染物排放标准GB 13223-2011。文章首先介绍了云南全省氮氧化物排放情况和趋势,概述了云南各火电厂氮氧化物排放现状及采取措施,然后根据不同的锅炉类型分别对常规煤粉炉、W形火焰炉及CFB炉机组进行脱硝改造分析,这对找出合理的达标脱硝技术路线、控制烟气污染物具有一定的参考价值。
The emission of NOxfrom thermal power plant increased due to the economy and energy consumption growed,the stricter atmospheric pollutants standard GB1322-2011 was issued by the government. The status and trend of NOxemission in Yunnan province was introduced in this article, the NOxemission status and control measures of thermal power plant were summarized, the denitration transformation of pulverized coal boiler, W-shaped flame boiler and CFB boiler were analysised. This result was valuable to find out reasonable denitration technology solutions and control measures of reducing gas pollutants.
