The aim of this research was to propose optimal operation conditions and system configuration for C02 Recovering Semi-closed Gas Thrbine System with CH4-02 firing. To reduce the C02 emission and protect the environment, it is needed to develop a clean and high-efficiency power generation system. Although higher turbine inlet temperature (TIT) derives higher system efficiency, it causes higher NOx emission in open gas turbine systems. The semi-closed gas turbine system with steam recirculation has been noted because of its high efficiency (ni)>60%, HHV ) without any NOx emission. There are many technical challenges in the realization of this system, such as materials and combustion control. We try to clarify the relationship between the emission properties from system (e.g., concentration of CO which is a regulated poison) and the geometry of gas path in a high temperature turbine. The calculation results clarify that the CO concentration is low, but strongly effected by the turbine geometry at a lean combustion surroundings, which is the realistic operating condition. And the necessity of wide and suitable length duct for lower CO emission is also clarified.
