摘要
火力发电一直是中国的主要发电方式,并且随着煤炭资源逐渐稀缺,燃烧优化和氮氧化物控制已成为大型电站的主要研究课题。氮氧化物(NOX)作为大型电站锅炉的重要排放物之一,对环境的污染极大。当前,大型电站锅炉通常使用氮氧化物浓度很低的时候进行燃烧,燃烧结合选择性催化还原进行联合脱硝,而氮氧化物浓度较低的情况下,燃烧会在某些操作条件下牺牲锅炉的经济性,因此应进行燃烧优化研究。
Thermal power generation has always been the main power generation method in China,and as coal resources become scarce,combustion optimization and nitrogen oxide control have become the main research topics of large power stations.Nitrogen oxides(NOX),as one of the important emissions of large-scale power station boilers,pollute the environment extremely.At present,large-scale power plant boilers usually burn when the concentration of nitrogen oxides is very low.Combustion is combined with selective catalytic reduction for joint denitrification.When the concentration of nitrogen oxides is low,combustion will sacrifice the boiler's economical performance under certain operating conditions.So combustion optimization studies should be carried out.
