Abstrakt

In order to improve thermal efficiency of gas turbine system and better control NOx emission, the injection of steam into a gas turbine combustor has been employed. This study has used both chemical equilibrium calculations and the counterflow diffusion flame calculations of methane-air flame aiming at the elucidation of the NOx reduction mechanism due to the steam injection. The GRI-Mech was employed for modeling the chemical reactions.
