Gaseous Fuel Assessment in Industrial Impinging Flames with Local Extinction Effects

The aim of this paper is to present a numerical model for the simulation of industrial flames that impinge on to materials surfaces. Modeling is used to account for heat release calculated by mixing and kinetically controlled mechanisms, as well as for turbulence closure and heat transfer by convection and radiation. The combustion and flow characteristics are modeled using a finite‐volume computational approach. Propane‐oxygen and methane‐oxygen premixed flames are simulated under high‐pressure conditions. It is shown how massive savings can be achieved through fuel substitution in industrial flames impinging on to solid surfaces for treatment purposes and local extinction effects are also discussed.
