| Abstract: | Based on a two-dimensional model with detailed combustion chemistry,combustion, heat transfer and NO emission in combustor-heater are numerically investigated.Attention was focused on the influence of the working parameters on the NO emissions.Results revealed that the excess air ratio and firing rate have significant influence on NO emissions in the unit.It is shown that mole fraction of NO decreases from 3.9E-5 to 1.8E-5 with increasing excess air ratio from 1.12 to 1.42 at constant firing rate.In additio... |
