• The system of oxygen/recycled flue gas combustion for the removal of carbon dioxide from pulverized-coal fired power plants, the combustion characteristics of pulverized coal, and the trial designing of a 1 000 MWe pulverized-coal power plant were studied. The flame propagation speed of pulverized-coal cloud was measured in a microgravity combustion chamber at O sub(2)/CO sub(2), O sub(2)/N sub(2) and O sub(2)/Ar atmosphere. NO sub(x) and SO sub(2) emissions from the system were investigated in the industrial-scale combustion test facilities. Based on these results and the previous works, the trial designing of a 1 000 MWe pulverized-coal fired power plant applying this combustion system was also studied. As for the heat absorption performance of the boiler furnace, a 3-dimensional numerical analysis was applied to a large utility boiler furnace. It was compared with another promising system CO sub(2)-recovery, pulverized-coal power plant combined with amine absorption process.
