摘要：
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. The numerical analysis has been performed by using the detailed elementary reaction mechanisms including NOx formation. The effect of flow field on the chemical reaction has been investigated bp using the methane-air counterflow diffusion flame aiming at the elucidation of the NOx reduction mechanism due to the steam injection. The influence of the amount of steam, the method of injection, the preheated air and fuel temperature has been investigated. The results show that the steam injection is effective for the reduction of NOx emission, and the reduction mechanism of NOx emission is clarified.
