This paper describes performance analysis of the oxygen-hydrogen combustion power generation system with respect to the effect of non-condensable gas, oxygen purity, and oxygen production energy. Residual oxygen and nitrogen concentrations at the combustor outlet by diluted H2O circulation are concentrated to 1.7 times higher compared to the case of the chemical reaction on oxygenhydrogen combustion when equivalence ratio is 0.9. A small amount of nitrogen (1% by volume) in purified oxygen is considered to result in the formation of NOx. Oxygen production energy slightly increases as the oxygen purity becomes higher from 95% to 99.6%. However, the energy of noncondensable gas removal decreases and the impact of NOx becomes smaller.
