Abstract
A numerical and experimental study of concentrations of combustion products and pollutant emissions in the case of combustion of premixed methane-hydrogen mixtures in a model combustion chamber of a gas-turbine power plant is performed. The mathematical model of combustion of methane--hydrogen mixtures used in the study ensures good qualitative and quantitative agreement between the numerical and experimental data on the main combustion products and also qualitative agreement on emissions of pollutants. In what follows, this mathematical model of combustion combined with the chosen kinetic mechanism of combustion can be used to analyze the emission characteristics of gas-turbine power plant combustion chambers designed for operation on hydrogen-containing mixtures.
