The authors newly propose and investigate the carbon-dioxide-recovering SOFC/GT combined power generation systems. In the systems, the fuel gas is at first introduced to the SOFC, and then its exhaust fuel gas is afterburned by carbon dioxide or water vapor added pure oxygen and drives the bottoming gas turbine. The exhaust gas of the gas turbine, which is composed of only carbon dioxide and water vapor, preheats the fuel and the additional gas, and then the carbon dioxide is recovered by only cooling and water condensation. As for the systems utilizing the natural gas, the overall efficiency (HHV) of the carbon dioxide added oxygen combustion type reaches 64.20%, and that of the water vapor added type 64.93%. As for the systems utilizing the coal gas, that of the carbon dioxide added oxygen combustion type is 58.58%, and that of the water vapor added type 60.37%. These values are sufficiently high, indicating that the proposed systems are worth further research and development.
