The flame temperatures of fuels increase as the fuel calorific value rises. When the fuel calorific value rises 8 MJ/m(3) or higher; the flame temperature is higher than that of natural gas, and so NOx production from nitrogen fixation is expected to increase significantly. Also, some gasified coal fuels contain fuel nitrogen, such as ammonia, if the hot/dry type gas clearing system is employed. These factors affect the combustion characteristics of the gasified coal fuel. lit this paper, we clarified the influence of gasified coal fuel properties on NOx arzd CO emissions through experiments rising a small diffusion burner and through numerical analysis based on reaction kinetics. The main results were as follows: 1 NH3 conversion to NOx increases with increasing CH4 concentration in gaseous fuel. ;2 If gaseous fuel contains CH4, there will be some specific equivalence ratio in the primary combustion zone for the minimum NH3 conversion to NOx in the two-staged combustion. 3 Its specific equivalence ratio in the primary combustion zone increases with decreasing CH4 concentration in gaseous fuel. 4 If the fuel contains a small percent of CH4, there is no influence of the CO/H-2 molar ratio in the fuel on the conversion rate of NH3 to NOx while there is an influence in the case where fuel contains no CH4. The conversion rate increases with rises in the CO/H-2 molar ratio. 5 As the pressure increases, the conversion rate of NH3 to NOx slightly decreases and the CO emission declines significantly. ;煤气燃料燃烧特性的研究 整体煤气化联合循环（IGCC）系统的发展为满足世界上未来煤炭利用发电的需求提供了具有成本效益和无害环境的技术。日本政府和日本的工业推动研究和发展IGCC系统。我们正在致力于开发整体煤气化联合循环燃气轮机的燃烧室使用低NOx燃烧技术。每个气体燃料生产从原材料中CO和氢为主要可燃成分,和少量的CH。气化煤燃料的成分和发热值相差很大取决于原材料和气化炉类型。气体燃料,产生的各种气体发生器,热值的MJ / m 4 - 13(3),这是十分之
