摘　　要：介绍降低电站燃气轮机NOx排放的主要技术,对注水/蒸汽、干式低NOx燃烧和选择性催化还原(SCR)3种控制NOx排放技术进行讨论,指出它们的优缺点和适用范围。分析认为,干式低NOx燃烧技术(DLN)是目前燃用天然气的燃机应优先采用的降低NOx排放的技术,但是干式低NOx燃烧器面临燃烧不稳定的困扰,燃烧稳定的区间很窄,采用该技术后燃机的调峰范围变小。The principal NOx emission control technologies in gas turbines were introduced.Three NOx control technologies including water/steam injection,dry low NOx(DLN) combustion,and selective catalytic reduction(SCR) were discussed.The advantages and disadvantages and scope of application were proposed.The analysis results show that DLN combustion technology will be the priority to reduce the NOx emission for gas turbines using natural gas.Combustion instabilities are the major challenges of the DLN combustor.Stability limits of advanced DLN combustors are very narrow.The range of peak load regulation of gas turbine with DLN combustor becomes narrow too.
