高热值气体燃料低NOx燃烧器开发

摘要

涉及一款高热值气体燃料低NOx燃烧器的研发。仿真预测了火焰长度、火焰刚性、NOx排放指标，并设计了试验样机，测试了各项参数。测试结果表明，该燃烧器火焰稳定性好，刚性强，能力调节比大，烧嘴轴向温度均匀性高，NOx排放指标改善了。%Research and development of a kind of low NOx emission burner with high calorific value gas fuel were carried out. Use of numerical simulation forecasted the flame length, flame rigidity and NOx emission index, moreover designed experimental prototype and measured various sorts of parameters. The measurement results show that the flame stability is fine, the flame rigidity is strong, the adjustment range is extensive, the burner axial temperature uniformity is even, the NOx emission index is improving.
