DESIGN AND MODELING OF SECOND GENERATION OXYGEN-FIRED CFB
A major drawback of the carbon capture and storage (CCS) technology is the additional energy required for the operation.This reduces the power plant efficiency and increases the cost of electricity.The following paper presents initial design parameters and modeling results of O2GEN-project, which focuses on increasing the inlet oxygen concentration and reducing the flue gas recirculation and energy penalty of the oxygen-fired CFB units.In Foster Wheelers first generation oxygen-fired CFBs, the inlet oxygen level is less than 30 %-vol, which makes the thermal design close to air-fired units.In the second generation oxy-CFBs, the inlet oxygen concentration is increased up to 40%-vol, which creates new challenges as the thermal power per unit volume is higher, but also enables new means to improve the net efficiency of the oxygen-fired power plant.This will result in a more environmentally and economically attractive technology to reduce carbon dioxide emissions from power generation.
