SUMMARY:Dome combustion hot blast stoves: Breakthrough technology reaches maturity
DESCRIPTION:Before the introduction of dome combustion technology in the 1990s (ref. Kalugin first “shaftless” hot stove in operation in 1992), steel producers relied on either internal or external combustion chamber design hot blast stoves, with their advantages and disadvantages with respect to investment, process performance, reliability and maintenance requirement. Both these designs have reached a high level of maturity during nearly 150 years of use in the global steel industry.

Over the past three decades, dome combustion technology was first embraced by the Russian steel industry and after the year 2000 by the Chinese steel industry. The design is currently considered the new industry standard for Greenfield Blast Furnace plants, in Asia in particular. Compared to the early design, later dome combustion hot blast stoves represent some steps forward, also driven by the implementation on a larger scale in the Chinese steel industry.

This article analyses designs of early and later generations, also based on findings at systems that have been in operation for multiple years. The authors compare the designs with respect to mixing and combustion performance as well as condition and integrity of the refractories, presenting how the analyses and findings have resulted in the latest generation burner and refractory design features as implemented in three ongoing projects for steel producers in India.
