Recently, oxy-fuel coal combustion has drawn attention as useful technique to achieve carbon dioxide capture and storage (CCS). This is the technique that enriches CO_2 in exhaust gas by the flue gas recirculation with additional pure O_2 to combustion atmosphere, which makes easy to capture CO_2. 0n the other hand, bubbling fluidized bed coal combustion has advantages of direct sulfur capturing in furnace by adding desulfurizing agents to bed material and decreasing of thermal NO_x as a result of low combustion temperature. However, oxy-fuel combustion behavior of coal in a bubbling fluidized bed is still unclear. In this study, we conducted the coal burning experiment under CO_2/O_2 using bubbling fluidized bed and compared oxy-fuel combustion behavior with air combustion behavior of coal. In addition, three coal samples having different nitrogen contents were tested to estimate the effect of raw coal properties on oxy-fuel combustion behaviors.
