Reheating furnaces use an energy-intensive process to bring steel slabs up to a desired rolling temperature. In order to increase the efficiency of a reheating furnace, oxygen enrichment and oxy-fuel technology can be utilized. Oxygen enrichment is the process of increasing the amount of oxygen found in the combustion air beyond the naturally occurring 21%; this technology is easily implemented on active reheating furnaces. Through the use of computational fluid dynamics (CFD), oxygen enrichment can be modeled and investigated for the resultant effects on efficiency, productivity, fuel and air usage, and emissions.
