High-temperature Shaftless Hot Air Stoves with Long Service Life for Blast Furnaces

摘要

The increase of hot blast temperature leads to shortening of coke consumption and increase of blast furnace productivity, it decreases operating cost considerably. Capital expenses for erection of hot-air stoves and their repair also effect on total cost-effectiveness of blast preheating. The degree of the achieved blast preheating temperature, capital expenses for erection and overhaul time of hot-air stove are determined first of all by their construction of hot-air stoves.
