A new scheme of O-2/CO2 combustion with partial CO2 removal from recycled gas is proposed. Through experiments and theoretical analysis of the system, the reduction of NO to N-2 and emission of NO were investigated for this new scheme. When CO2 is partially removed from the recycled gas, a high gas recirculation ratio is needed to maintain the O-2 concentration at the furnace entrance and the stoichiometric O-2 amount necessary for the burn-out of coal. It was found that this gas recirculation ratio increased with the CO2 removal ratio from the recycled gas. The gas recirculation ratio could be as high as 98.9%; i.e., only 1.1% of the flue gas was exhausted. The CO2 concentration in the flue gas was above 95%, which made its capture much easier and more economical. The global conversion ratio from fuel N to exhausted NO decreased as the CO2 removal ratio from the recycled gas increased. At a CO2 removal ratio of 15%, the global conversion ratio from fuel N to exhausted NO became as low as 3.95 X 10(-3), i.e., down to only 1/85 of that of conventional combustion in air. These results suggested that, with the new scheme of O-2/CO2 combustion proposed in this work, superlow NO emission and easy CO2 capture could be realized simultaneously.
