高炉热风炉是采用蓄热的原理进行间断操作的热工设备,即在燃烧期热风炉蓄热室的格子砖受高温烟气加热,然后,转换到送风期,向热风炉送入冷风,由高温格子砖加热。但是随着送风时间的延续,格子砖温度逐渐下降,热风温度也逐渐下降。为了不影响热风温度,在热风炉的热风出口侧的混合室内或热风总管内将热风与冷风或低温风混合,以达到规定进入高炉的风温。
Blast furnace stove is the use of heat storage principle of intermittent operation of the thermal equipment, that is, during the burning period regenerator hot air grid brick bricks by the high temperature flue gas heating, and then switch to the air supply period, Heated by high temperature lattice brick. However, with the extension of the blowing time, the temperature of the lattice brick gradually decreased and the temperature of the hot air gradually decreased. In order not to affect the temperature of the hot air, the hot air is mixed with cold air or low temperature air in the mixing chamber on the hot air outlet side of the hot air oven or in the hot air main in order to set the temperature of air entering the blast furnace.
