Application of Oxygen-Enriched Combustion in an Industrial Reheating Furnace Using CFD (Room 207 D)

An important part of the hot rolling process is the reheating of steel products to target temperature using combustion of natural gas in a furnace. To increase energy efficiency of this reheating process, oxygen enrichment can be used with high entrainment of reaction product gases to distribute the combustion reaction area. The modeling of various configurations was undertaken using computational fluid dynamics to use oxygen enrichment or oxy-fuel in order to avoid changes in the furnace zone temperatures while reducing fuel usage. Effects on the combustion, temperature distribution, species and heat transfer to the steel product are under study.
