High blast temperature is one of the important technical characteristics of modern blast furnace (BF), which is also an important technical approach for the green development of ironmaking. Increase blast temperature can improve and promote the BF operation smooth and stable, reduce coke rate, fuel consumption and CO2 emission. Dome combustion hot blast stove technology has been applied in Shougang Jingtang’s 5500m3 BF for 8 years. Under the condition of burning single BF gas, high efficiency energy conversion and over 1250 degree high blast temperature have achieved. The combustion and heat transformation process were researched by numerical simulation technology to optimize the structure design. The high efficiency annular ceramic burner and checker brick were developed and applied, the flue gas waste heat was recovered and reused to preheat the combustion air and gas. Prominent achievement of high blast temperature under the condition single BF gas burning has been realized.
