火电厂氮氧化物产排放量的核算方法研究

摘要

During the 12th Five -Year Plan period (2011 -2015 ), restrictions on nitrogen oxide emission were added to China's energy - saving and emission reduction program. The nitrogen oxide emissions from thermal power plants should be stud- ied. This paper first analyzes the generation mechanism of nitrogen oxide in the thermal power plant. The nitrogen oxides are mainly formed in three ways, namely fuel type nitrogen oxide, thermal type nitrogen oxide and fast type nitrogen oxide. Factors in- fluencing the generation amount of nitrogen oxide in thermal power were analyzed. A detailed analysis on the efficiency of nitrogen oxide control measures and technologies for nitrogen oxide emission reduction was conducted to gives the formula of nitrogen oxide emissions in the thermal power plant.%＂十二五＂期间,中国节能减排工作中增加了氮氧化物的约束性指标,对火电厂氮氧化物产生排放规律进行深入研究的重要性凸显。本文首先分析了火电厂氮氧化物产生的机理,氮氧化物的生成途径主要有三种,即燃料型NOx、热力型NOx、快速型NOx,进而分析了影响火电锅炉氮氧化物产生量的因素,详细分析了火电厂NOx控制措施技术类型及其对削减NOx排放量的效率,并最终给出火电厂NOx排放量的计算公式。
