A method of generating power with sequestration of carbon-dioxide includes compressing ambient air, separating substantially pure oxygen from the air and then further compressing the oxygen. After compression the oxygen is divided into a first oxygen stream and a second oxygen stream. The first oxygen stream and a solid fuel, such as coal, are introduced into a solid-fuel gasifier for creating a combustible gas. The gas is combusted in the presence of the second oxygen stream, water is introduced into the combuster during the combustion for generating an exhaust stream of carbon dioxide and steam. The exhaust gas is then past through a turbine for driving the turbine and generating power. The exhaust gas is then so that the carbon dioxide gas may be separated from the water and collected. Introducing water into the combuster during the combustion increases the mass and the volume flow of the exhaust stream passing through the turbine, thereby elevating the amount of power generated by the turbine. |
