| Abstract Scope |
The converter process which accounts for 70% of steel production in the world is known that the CO content in the off-gas is high. Also, off-gas has a large amount of sensible heat, so research is under way on how to reuse it. Among them, studies on the post-combustion which increases the heat of the converter through the combustion of CO gas are being carried out. However, this technique causes problems such as wall refractory damage. Therefore, it is necessary to study the heat transfer condition to the lower part by post-combustion. In this study, analysis of gas flow and temperature distribution in the converter according to the O2 gas injection was conducted by the shape of nozzle and the position of nozzle tip as calculation variables. As a result, the higher the position of nozzle tip, gas velocity was lower and gas temperature was higher in the lower part. |
