摘　　要：通过精确测量各种工况下炉膛顶部监测点温度和烟道烟气中NO含量,研究了液化气喷枪位置、旋流数和蓄热式预热工况等工艺因素对平焰燃气炉烟气中NO生成特性的影响规律。研究结果表明,通过调整液化气喷枪位置,改变旋流数和采用蓄热式预热空气等措施可以有效降低平焰燃烧烟气中NO的含量,最大降幅分别为52.71%、35%和35.41%。Temperature in the furnace top and concentration of NO in flue gas is measured accurately and the effects of position of liquefied gas nozzle, swirling number and regenerative preheating process on NO in flue gas are studied in this paper.The results show that concentration of NO in flue gas can be effectively reduced by repositioning nozzle of liquefied gas,changing swirl number and regenerative preheating and the biggest drop should be 52. 71%, 35% and 35. 41%.
