Flue gas furnace is an important equipment of blast furnace pulverized coal pulverizing system

into the late campaign

because inside the furnace

furnace lining shedding on tilt aging

refractories severely eroded and damaged

resulting in leakage of the furnace body

heat insulation ability and flue gas furnace heat storage effect is poor

leading to reduction in the amount of the powder

unable to ensure the normal coal injection of blast furnace. Through application in gas furnace spraying the surface of new refractory material

high temperature far infrared solid fine repair techniques

enhance the oven heat insulation effect

increase the radiation flue gas furnace internal exchange capacity

thermal efficiency is improved

energy saving. In one fell swoop overcome because of the insufficient quantity of flue gas and the coal pulverizing adjustment difficulties

the key to play the effect of mill pulverizing capacity

improve the mill production efficiency

meet the requirement of blast furnace coal injection

obvious comprehensive benefits.
