The function of the hot blast stove is to heat the blast to the required temperature to improve the benefit and efficiency of the blast furnace; it works according to the principle of "heat storage". The gas is burned in the combustion chamber, and the high-temperature exhaust gas passes through the checker bricks to store heat. When the checker bricks are fully heated, the hot blast stove can be changed to air supply. At this time, close the combustion valves and open the air supply valves, and the cold air enters When the blast furnace is equipped with 3-4 hot blast stoves/single-furnace air supply, two or three are heated and one air is supplied; when alternately replaced/parallel air supply, two are heated.
