Abstract: A cogeneration plant is provided that includes a gas turbine, a heat recovery steam generator, a steam turbine and a cooler/condenser. A division module is provided at a division point, via which downstream the heat recovery steam generator the combustion gas is cooled and dehumidified in the cooler/condenser and then divided into a first combustion gas flow and a second combustion gas flow. A second condenser is provided for receiving the second combustion gas flow to separate contained carbon dioxide from contained water by condensation of the water. The cogeneration plant further includes a heater and a compressor for receiving the first combustion gas flow, which is heated, compressed and partly extracted to by-pass the combustor for cooling of the gas turbine before it enters the combustor and mix with the flow of oxygen and fuel to be burned in the gas turbine.

Abstract: A method for operating a gas turbine engine unit with a compressor section operable by a O2-rich first working fluid and a turbine section operable by a O2-lean second working fluid, and a unit for an oxygen extraction process, the method including: discharging all O2-rich first working fluid of the compressor section from a compressor of the compressor section to the unit for the oxygen extraction process so that all O2-rich first working fluid of the compressor section is used for the oxygen extraction process, extracting O2 from the O2-rich first working fluid by an oxygen extraction process, cooling at least one wall of the at least one combustion chamber of the combustion section by the O2-rich first working fluid while bypassing the at least one combustion chamber and heating the O2-rich first working fluid while by-passing the at least one combustion chamber.

Abstract: An arrangement for concentrated solar power energy conversion is provided having a receiving tower founded on a ground level, at least one receiver attached to the receiving tower in a receiving height above the ground level, further having at least one ground station positioned on ground level, wherein the receiver has at least one solar collector to receive concentrated sunlight, wherein the solar collector has a heat exchanger exchanging heat with a process fluid to be heated up. The receiver also has at least one top compressor to compress the process fluid before it enters the heat exchanger, wherein the receiver has at least one top compressor driving unit driving the top compressor, wherein the ground station has at least one ground turbine driving a driven unit, wherein the ground station receives the process fluid from the receiver to be expanded in the ground turbine.

Abstract: A converted telephone plug inserted into the first jack of a traditional, local telephony network breaks the normal connection to a public switched telephony network (PSTN) and reroutes signals to special telephony equipment for further connection to a modern access network. The advantages are that local analog telephones, can be used as interfaces also against the modern network and that installation becomes easy.

Abstract: A method of combusting a fuel, and a combustion plant are proposed. The combustion plant comprises a first circuit (1) with a gasifying reactor (3) to produce a combustible gas and a degassed, combustible rest product from the fuel. The combustible gas is supplied to a first combustion chamber (6) and there it is combusted while forming combustion gases. First means (8, 9) are arranged to take advantage of the energy in these gases. The plant further comprises a second circuit (2) with a second combustion chamber (15) which is supplied with the combustible rest product from the gasifying reactor (3). The rest product is combusted in the second combustion chamber (15) while forming combustion gases. The second circuit (2) further comprises second means (23, 24) for taking advantage of the energy of the combustion gases produced in the second circuit (2).
