Oxy-fuel combustion is one of the important technologies for carbon capture and storage technology to be applied in coal power plants. This study is aimed to determine key design parameters related to the flue gas recirculation and dehumidification of the recycled flue gas. In this study, for the first generation of an Oxy-PC combustion system in which air separation unit(ASU) and flue gas recirculation (FGR) are integrated with an existing power plant, parametric study has been performed through engineering approaches, i.e. (1) 0-dimensional heat and energy balance, (2) Experimental approaches in a reduced-scale combustion chamber and (3) 3-dimensional numerical simulation. Effects of the flue gas recirculation ratio and dehumidification to combustion characteristics in the combustion system were investigated in the combustion systems of various scales.
