Working principle of hot blast stove

Working principle of hot blast stove Hot blast stove is a thermal power machine. It has been widely used in my country in the late 1970s. It has become a replacement product of electric heat source and traditional steam power heat source in many industries. There are many varieties and series of hot blast stoves. They are divided into two types: hand-fired and machine-fired by the way of adding coal, and coal, oil, and gas stoves by the type of fuel.GCr15 Bearing Steel Effect Of Tempering Temperature On Microstructure And PropertiesThe function of the blast furnace hot blast furnace is to heat the blast to the required temperature to improve the efficiency and efficiency of the blast furnace; it works according to the principle of "regenerative storage". The gas is burned in the combustion chamber, and the high-temperature exhaust gas passes through the checkered bricks to store heat. When the checkered bricks are fully heated, the hot blast stove can be changed to air supply. At this time, all combustion valves are closed, and all air supply valves are opened. Checkered bricks are heated and sent out. When the blast furnace is equipped with 3-4 hot blast stoves, two or three are heated and one is supplied with air. When the blast furnace is replaced in turn, two are heated.Vacuum carburizing process of auto parts There are many varieties and series of hot blast stoves. They are divided into two types: hand-fired and machine-fired by the way of adding coal; It is indirect type and direct type, and can be divided into combined type and split type according to the arrangement of heat exchangers, and coal pulverizers are equipped on large furnaces.Aerospace material vacuum heat treatment furnace
