烟气炉是高炉喷煤制粉系统的重要设备，进入炉役后期，因炉子内部日倾老化、炉衬脱落，耐材受到严重侵蚀和破坏，造成炉体漏风，其隔热保温能力和烟气炉蓄热效果差，导致制粉量减少，无法保证高炉的正常喷煤。通过在烟气炉的内表面喷涂新型耐材高温远红外固体精进行技术修复，增强了炉子的隔热保温效果，加大了烟气炉内部的辐射交换能力，热效率得到显著提高，节能降耗。一举攻克了因烟气量的不足而使制粉调节困难，影响磨机制粉能力发挥的关键，提高了磨机的生产效率，满足了高炉的喷煤要求，综合效益明显。

Flue gas furnace is an im portant equipm ent of blast furnace pulverized coal pulverizing system , into the late cam paign, because inside the furnace, furnace lining shedding on tilt aging, refractories severely eroded and dam aged, resulting in leakage of the furnace body, heat insulation ability and flue gas furnace heat storage effect is poor, leading to reduction in the am ountofthe pow der,unable to ensure the norm alcoalinjection ofblastfurnace.Through application in gas furnace spraying the surface ofnew refractory m aterial,high tem perature farinfrared solid fine repairtechniques,enhance the oven heatinsulation effect,increase the radiation flue gas furnace internalexchange capacity,therm alefficiency is im proved, energy saving.In one fellsw oop overcom e because ofthe insufficientquantity offlue gas and the coalpulverizing adjustm ent difficulties, the key to play the effect of m ill pulverizing capacity, im prove the m ill production efficiency, m eet the requirem entofblastfurnace coalinjection,obvious com prehensive benefits.
