Numerical Modeling of Oxygen Enhanced Combustion and Transient Heating Characteristics in a Reheating Furnace
Original language description
In this work an experimental and numerical investigation of oxygen enhanced combustion (OEC) was done for different oxygen concentrations on a 750 kW lab-scale furnace. Temperatures in the furnace and heat fluxes to the walls were measured and used to validate the CFD model especially the chemical reaction mechanism for applicability in OEC. Flame temperature and shape were in good agreement as well as the heat fluxes to the walls for all combustion cases. An increase of the furnace efficiency was determined from 61% for combustion with air and 73.4% for OEC with an O2 concentration of 30.8vol% in the oxidizer. The same trend was predicted by the numerical simulations. Additionally an industrial walking hearth furnace to reheat steel billets was simulated by the CFD model for air-fuel and OEC with an enrichment level of 25vol% O2. Furnace operation revealed a fuel saving of 8% compared to the air case. The transient simulation of the billets showed that the similar billet surface temperature was achie
