The function of the iron-making blast furnace hot blast stove is to heat the blast to the required temperature to improve the benefit and efficiency of the blast furnace; Hot Air Stove it works on the principle of "heat storage". The gas is burned in the combustion chamber, Hot Air Stove and the high-temperature exhaust gas passes through the checker bricks to store heat.
When the checker bricks are fully heated, the hot air stove can be changed to air supply. At this time, Hot Air Stove the relevant combustion valves are closed, the air supply valves are opened, Hot Air Stove and the cold air passes through Checker bricks are heated and sent out. When the blast furnace is equipped with 3-4 hot blast stoves/"single-furnace supply", Hot Air Stove two or three will be heated, and one will supply air;Hot Air Stove when alternate replacement/"parallel supply", two will be heated.
The direct high-purification hot-blast stove uses fuel to burn directly, forms hot air through high-purification treatment, Hot Air Stove and directly contacts the material for heating and drying or baking. The fuel consumption of this method is about half that of using steam or other indirect heaters. Therefore, Hot Air Stove the direct high-purification hot air can be used without affecting the quality of the dried product.
