Abstract

The previous researches show the great effect of soot on natural gas flame radiation. The addition of soot into methane flame is widely proposed by the researchers as a good method to enhance radiation from non-luminous flames. But the effect of adding soot on the chain reactions of methane combustion and NO & CO emission have been not reviewed. The present study investigates the effects of adding gaseous soot on the progress of natural gas combustion and NO & CO emission in the zero-dimensional zone by means of GRI 3.0 mechanism in the Cantera python package. Also, methane incomplete combustion products are considered as an additive to control the pollutants. The results indicate that the addition of gaseous soot into natural-gas flame leads to increase in adiabatic temperature, the rate of decomposition reactions of fuel and brings more CO and NO production. In the other hand, the addition of methane-air incomplete combustion products into natural gas reaction cause to reduce CO production and decrease in the adiabatic flame temperature. So, in order to enhance radiation of methane flame and pollutants reduction the additive that composed of of gaseous soot and methane-air incomplete combustion can be used.
