摘　　要：将煤的含氮模型化合物吡啶配入柴油中模拟煤中氮的存在形式，考察了该混合燃料在四喷嘴对置式气化炉实验装置中，不同氧碳比对气化室出口NH3生成率的影响．结果表明，在氧碳比1，05～1．97m。／kg范围内，NH3生成率存在最大值；当燃料中N含量过高时，NH3生成率较低；碳转化率和气化炉型也是影响NH3生成率的重要因素．The coal nitrogen-containing model compound pyridine was added to diesel oil to simulate the existence of coal nitrogen. The gasification process of this fuel combination was taken in a laboratory platform of opposed multi-burner gasifier, which gasified temperature approaching factory. Effects of the ratio of O2 to carbon on the yields of NH3 and its formation process were researched. The results show the maximum yield exists in the O2/C ratio of 1.05 - 1.97 m3/kg. The fuel combination with the highest nitrogen content gets the lowest yield of NH3. The carbon conversion and gasifier type also influence the yield of NH3.
