We are working on one of methods proposed on technology of carbon dioxide capture and storage, which is targeted at coal-firing power plant due to the increase in carbon dioxide which is the main cause of global warming. Oxy-coal fired power plant of systems is classified as oxygen production, oxygen combustion, boiler, desulfuration and collection, and carbon dioxide recovery. It needs 'oxygen production and optimization of carbon dioxide recovery,' and 'optimization of flue gas recirculation' to analyze the system of the thermodynamic assessment. Young Dong power plant part 1 as our case of research is separated from the same condition of existing steam cycle, and the condition of steam cycle changed on ultra super critical working condition. We plan to do the optimization of flue gas recirculation depending on each condition, which is necessary for the thermodynamic assessment, and further more an exergy analysis is under consideration based on heat and mass balance. A complicated oxy-coal fired generation system is divided by four parts: air separation unit (ASU), air-gas, water-steam, and carbon dioxide compression and purification unit (CPU). Enough parameters is found out and should be optimized for abovementioned four parts. Now we are in the works for analysis of a part of water-steam, and enough working parameters in these parts are doing analysis on referring to young-dong power plant part 1 of the drawing chart and simple working conditions. The detailed working conditions are assumed because of not yet securing.
