摘　　要：通过对褐煤和烟煤进行理论分析,得出褐煤的着火热比烟煤大,且褐煤的火焰检测初始燃烧区比烟煤远。并对炉膛火焰燃烧情况进行了分析,得出火焰检测装置应安装在炉膛中心火焰旋转的下游、燃烧器水平中心线的上侧的结论。Based on theoretical analysis of bituminous coal and brown coal,the paper shows that ignition heat of brown coal is more than bituminous coal and the prime burning area of ignition heat is bigger than bituminous coal. It was concluded that the flame detection devices should be installed in downstream rotation area of the furnace centre flame and upside of the horizontal center line of the burner through analysis of flame combustion.
