Abstract

To reduce CO_2 emission and environmental impact, it is needed to develop the clean and higher efficiency power generation system. So, the CO_2 recovering semi closed gas turbine with CH_4-O_2 firing has been noted with its high efficiency and low emission capability. Such a high efficiency is a result of a high turbine inlet temperature. Though, high temperature causes the increase of emission level such as CO and H_2 because of an incomplete reaction. Although, incomplete reaction can be suppressed in an oxidation surroundings actualized by excess oxygen feeding, it causes a decrease of system efficiency. So, chemical kinetic calculations are carried out to clarify the trade-off relationship between these parameters. The characteristics of pollutant formation and its oxidation processes are analyzed. An optimal equivalent ratio for the total system efficiency and emission is also estimated.
