【 摘 要 】

Power generation systems based on the oxy-coal combustion with carbon dioxide capture and storage (CCS) capability are being proposed and discussed lately. The proposed systems are evolving and various alternatives are to be comparatively evaluated. This paper presents a proposed approach for performance evaluation of a commercial scale power plant, which is currently being considered for ‘retrofitting’ for the demonstration of the concept. System components to be included in the discussion are listed. Evaluation criteria in terms of performance and economics are summarized based on the system heat and mass balance and simple performance parameters such as the fuel to power efficiency and brief introduction of the 2nd law analysis. Cases are selected for comparative evaluation, based on the site-specific requirements. With limited information available, preliminary evaluation is attempted for the cases.
