摘　　要：在二维平面射流中进行了燃料型NO的实验研究,采用在甲烷中加入NH_3的方法来模拟燃料氮。实验结果表明:实验过程中生成的NO主要是燃料型NO,热力型NO和快速型NO占排放的总NO的比例很小,同时随着NH_3的增加,NO迅速增加,并且NO浓度沿轴向呈双峰分布。The process of Fuel-NO formation is experimentally studied in a methane/Air planar jet turbulent flame by adding a small amount of ammonia (NH3) in fuel to simulate fuel nitrogen. It is shown that the NO generated in experiment process are mainly contributed by fuel NO, where the contribution of thermal NO and promotion NO are very little. The fuel NO concentrations increase sharply with increase of the amount of ammonia being added, and their distributions along the axis appear characteristics of two peaks.

关 键 词：燃料型NO 平面射流 双峰分布
