Background

At present, coal-fired hot blast stoves are still widely used in many fields such as heating, stoving. Its greatest drawback is that it is neither energy-saving nor environmentally friendly. The main expression is that on one hand, the heat exchanger of the hot blast stove is seriously accumulated with dust on the heating surface and is very difficult to clean. According to six months of a heating period in northern areas, the thickness of the ash deposited on the heating surface of the heat exchanger reaches 8 mm, the heat conductivity coefficient of the ash is only 1/600-800 of iron, the energy consumption is increased gradually, the heat efficiency is greatly reduced, and the energy which is already tense is more tense. Meanwhile, the service life of heat exchange equipment of the hot blast stove is greatly shortened due to high-concentration smoke abrasion. On the other hand, during the operation of the coal-fired hot blast stove, a certain amount of smoke and dust is discharged to the atmosphere, so that the atmospheric pollution is promoted, and the originally fragile atmospheric environment becomes more fragile.

The existing hot blast stove usually adopts cold air to enter a combustion chamber from an air inlet and be heated and then is discharged from an air outlet to obtain hot air, and in the process, because fuel is not sufficiently combusted or the fuel quality is not high, the generated smoke often contains solid particles such as dust and the like. Secondly, ash and slag formed after combustion in the combustion chamber easily form suspended dust in the falling process, so that not only is the environment polluted, but also the breathing obstruction is caused to the working personnel, and the body health is influenced. Thirdly, because the hot-blast furnace is in the work of higher temperature, the lime-ash temperature of formation also can be higher, when the ash storehouse is piled up full, clearance personnel can't be close to, very easily causes personnel's scald.
