Abstract: This invention relates to a method and plant for combined electric energy and water production, where the method comprises feeding substantially pure oxygen and a hydrocarbon fuel in a stochiometric ratio to a combustor (5), combusting the oxygen and hydrocarbon feed for forming an exhaust gas at comparatively high temperature and pressure, passing the exhaust gas at high temperature and pressure to an expander (7) that runs an electric generator (8) and an exhaust gas compressor (9), passing the exhaust gass exiting the expander to an exhaust gas cooler (11) which cools the gas to a temperature above the steam condensation temperature, passing the exhaust gas exiting the exhaust gas cooler to the exhaust gas compressor for pressurising, and passing the pressurised exhaust gas to an exhaust gas condenser (14) where the exhaust gas is condensed and thus separated into a substantially pure water fraction and a gaseous CO.

Abstract: A rotor blade or a stator blade for rotary machinery is disclosed where the rotor/stator blade comprises a number of thin blade plates. A plurality of the rotor/stator blades are provided with at least one hole forming at least one supply duct when the blade plates are stacked on top of each other to form the rotor/stator blade. The blade plates are joined together by means of sintering such that a solid rotor/stator blade with an outer surface is formed.
