Ammonia is reference component of nitrogen contained particle and its influence on nitric oxides emission during combustion was investigated. The combustion process was performed with use of modern concept of High Temperature Air Combustion (HiTAC) technology called High Temperature Two Stage Combustion (HTTSC). The research was focused on numerical simulation of NO formation during this process. Numerical analysis of nitric oxides formation along the combustion chamber was conducted. Three numerical models were investigated using Cantera reaction kinetics environment; GRI 3.0, Tian and Konnov. The lowest emission rates were obtained for local air excess ratios λ = 0.45 and 0.6 on the first combustion stage. Absolute NO emission for GRI 3.0 was 24% higher than other mechanisms and trend for λ = 0.45 indicated greater emission than for 0.6. For all cases the final oxygen content in flue gases was kept at level of 7.9%. The results of numerical analysis indicated high compliance with experimental outcomes for high contents of ammonia in gas fuel.
