Flames, adjustment stoichiometric

The regenerators were included in the model to account for potential changes in air preheat temperature. The checkers were modelled as a porous media subject to radiative and convective heat transfer. A baseline case with a stoichiometric ratio of 1.12 (12% excess air) was compared to an OENR case with a primary SR reduced to 1.06 and an overall SR kept at 1.12. For both case, the glass throat temperature was controlled and kept constant to 1400 C by a PID controller which adjusted the air and fuel flow rates, so that the reduction in fuel consumption can be estimated. The oxygen injections for the OENR case are located on the opposite side of the flame near the exhaust port.
