Abstract

Abstract: Based on the analogy with steady counter flow reactor, a 1D time-averaged model with detailed kinetics is developed, which is applicable to modeling of production of syngas from fuel-rich partial combustion in reversal flow burner (RFB). The model is evaluated by comparing its predictions of temperature distributions and major syngas components in RFB with experimental data, good agreement between experimental results and predictions is observed. The model is then used to study the influence of mixture velocity, equivalence ratio and heat loss on the combustion characteristics in RFB. It is demonstrated that huge computational time can be saved by a factor of 140 using the developed model compared to the complete transient model. The developed model can be used for quick optimal design of syngas production in RFB with greatly reduced computational time and high accuracy. Highlights: A time-averaged model with detailed kinetics for reversal flow burner is developed. The model can be used for quick optimal design of RFB with high accuracy. The developed model can be used for quick prediction of syngas production. Huge computational time can be saved by the developed model. Computational time can be reduced by a factor of 140by the developed model.
