The SIP oxygen pulsing technology was commissioned in late 2020 on the 40-tuyere thyssenkrupp Steel Europe Schwelgern BF1 in Germany, and demonstrated immediate improvements in eta-CO. The technology reduced the total fuel rate and also allowed an increase in the ratio of pulverized coal injectionto coke. These results demonstrate both a reduction in Opex as well as a reduction in the carbon emissions from the blast furnace, within a very short payback period. This paper will discuss the technology and the learnings from the Schwelgern BF1 operations with oxygen pulsing.
