A two-dimensional detailed numerical combustion analysis is performed to explore syngas combustion inside a non-premixed combustion chamber. A detailed transport model coupled with a chemical kinetic mechanism is used to study combustion behavior. The combustion chamber supplied with syngas comprising Hydrogen (H₂), Carbon Monoxide (CO), and Nitrogen (N₂) as constituents such that H₂ and CO molar ratios are changed while N₂ constant. The numerical study uses co-flow air delivery to control the inlet air temperature to analyze its impact on reaction rate performance. The study analyzes both the ignition zone structure and the effects of changing H₂/CO molar ratios on adiabatic flame temperature. Perfecting syngas H₂/CO ratios together with inlet air temperature leads to best reaction rate balances between H₂ and CO molar ratios. The simulated results reveal information about temperature distribution along with reaction rates and flame topologies that help
perfect combustion performance.
