Abstract

Effects of adding carbon dioxide on methane/hydrogen combustion are numerically studied in a swirl burner. Mole fractions of carbon dioxide and nitrogen monoxide at the exhaust were analyzed using different carbon dioxide blends ranging from 0-25% in CO2/air mixtures. A simulation was carried out by using SST k-ω turbulence model and finite rate chemistry model with flamelet concept included. Calculations using a detailed chemical kinetic scheme to predict the emission characteristics were also attempted to determine concentration values more accurately. Results show that by adding carbon dioxide to air significant reduction in CO2 and NO emissions can be achieved, whereas temperature of the flame also decreased. The results can provide information for emission reduction of gas turbines, saving costs of later post-treatments.
