Key techniques of supplying high temperature blast to blast furnace by stove

Improving the uniformity of high temperature fume and cold blast mixture on the cross section of heat accumulating chamber to intensify the heat exchange in the stove and using an advanced burner to raise the dome temperature significantly are reasonable and efficient methods to increase the hot blast temperature. Thus the average temperature of hot blast can be as high as 1177°C, while the highest hot blast temperature is 1210°C.
