摘要:
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.

A plurality of pressure-tight unit-cell individual heat exchanger elements (10) are joined by manifold flanges (16) to form an integrated plate-fin heat exchanger. Each individual heat exchanger element (10) contains all the features of a complete counter-flow heat exchanger (40) with inlet and exit ports (14, 15), air distribution headers (16) and heat transfer fins (20, 21, 22) brazed into a single unit.

A Brayton cycle air compressor system having two turbine-compressors and a recuperated combustion chamber interconnected. A portion of the hot compressed high pressure air is used as combustion air for the combustion chamber. In addition, a portion of the combustion air may be used as the heat source for regenerating the desiccant in the optional air dryers.

摘要:
Une roue à aubes centrifuge comprend un moyeu formé autour d'un axe de rotation (14) avec une pluralité d'aubes s'étendant sensiblement radialement (26) et fixées au moyeu. Les aubes ont une hauteur mesurée dans une direction radiale à partir du moyeu. Un plan imaginaire s'étendant dans une direction normale à l'axe de rotation est utilisé pour définir une vue en coupe de la roue à aubes. Un premier cercle concentrique (22) et un second cercle concentrique (22') sont formés dans le plan, leur centre étant l'axe de rotation. Le premier cercle passe par un point sur le moyeu situé le plus proche de l'axe de rotation. Le second cercle possède un rayon plus grand que celui du premier cercle d'une quantité égale à 5 % de la hauteur de l'aube, une portion (24) du moyeu s'étendant à l'extérieur du second cercle.
