21.2.1.1 High Flame Temperature and Heat Transfer High adiabatic ﬂame temperature and high heat release rate and transfer are the main beneﬁts for which traditional applications of oxy-fuel burners were developed. Welding with an oxy-acetylene ﬂame, ﬂame polishing of glass surfaces, and oxygen cutting of steel plates are some of examples of applications that take advantage of these oxy-fuel ﬂame characteristics. 21.2.1.2 Fuel Savings The use of oxygen in a heating process eliminates the nitrogen introduced with combustion air from the process and hence eliminates the energy required to heat the nitrogen from inlet temperature to outlet temperature. For high-temperature processes (>2200°F or 1200°C) with no heat recovery, fuel savings when using oxygen can exceed 50%. As heat recovery is employed with the air combustion system, the savings achievable when switching to oxy-fuel combustion are reduced. A simple heat and mass balance on the furnace under each operating condition can provide accurate
