电站燃煤生成排放的氮氧化物是造成大气污染的有害物质。本文结合目前电站燃用不同性能煤种的混煤这一新动向，研究了混煤燃烧过程中氮氧化物的生成规律，提出了混煤氮氧化物形成的化学动力学模型，并将计算机模拟结果与实验实测值进行了比较、分析．为燃用混煤电站降低氮氧化物排放提供理论依据。
Nitrogen oxides generated by coal-fired power plants are harmful substances that cause air pollution. Combining with the new trend of coal blending with different performance coal at current power stations, this paper studies the formation rules of nitrogen oxides during the combustion of mixed coal and proposes a chemical kinetic model for the formation of nitrogen oxides in the mixed coal. The computer simulation Results and experimental measurements were compared and analyzed. It provides a theoretical basis for burning mixed coal power station to reduce nitrogen oxides emission.
