Abstract: A combined cycle power plant with a gas and steam turbine system arranged on a single shaft and integrated with a cogeneration plant having a heat consumer such as a district heating system or industrial plant, including one or more steam extractions at an intermediate-pressure steam turbine that are arranged at the upper casing half-shell of the turbine and extraction steam lines that lead the extracted steam to heat exchangers of the cogeneration plant. The steam extraction outlets are arranged either singly at or near the uppermost point of the casing or in pairs to either side of the uppermost point of the casing. The specific arrangement of the extractions allows a floor-mounting of the single-shaft combined cycle power plant and as such a cost and space efficient realization of the power plant.

Abstract: A method for positioning a rotor of a gas turbine automatically is provided that includes gathering data with a control unit, and processing this data to bring the rotor to a desired position which is set according a Human Machine Interface (HMI). The indication of the lay of the rotor to the control unit is done by a key phasor, which includes a sensor which gets a digital pulse for each revolution of a phasor cam wheel. This digital pulse is used to give the information of the lay of the rotor to the control unit.

Abstract: A method for more efficiently removing pollutant gases from flue gases of a solid-fueled steam generator includes storing a silo a carbonaceous sorbent in a powdered form; extracting a superheated steam from a superheated steam source; and reducing a temperature, pressure and moisture content of the superheated steam to provide a processed steam of a desired pressure, temperature and moisture content. The method further includes providing a sorbent mill receiving the carbonaceous sorbent and the processed steam, wherein the sorbent mill is operable to de-agglomerate and comminute the carbonaceous sorbent using the processed steam to provide a processed sorbent. Further the method includes injecting the processed sorbent into the flue gases at a desired location in the solid-fueled steam generator thereby adsorbing the pollutants therefrom; and collecting and thereby remove the carbonaceous sorbent from the flue gas fluidly downstream from the desired location.

Abstract: The invention provides a coupling assembly for connecting two shafts. A first shaft includes an outward flange on one end thereof with a plurality of first holes extending through the outward flange around an axis of the first shaft. A second shaft is a hollow shaft including an inward flange on one end thereof with a plurality of second holes extending through the inward flange with same diameter of the first holes and aligning with the respective first holes. The coupling assembly includes: a coupling bolt with thread on a first end and a second end thereof, which is inserted in the first hole and the second hole. A first nut is engaged with the first end of the coupling bolt. A second nut engaged with the second end of the coupling bolt. An expansion sleeve is with its inner hole tapering from one end to another end thereof. The expansion sleeve is interposed between the coupling bolt and the first and second hole to secure the coupling bolt relative to the first and second hole; the second nut is formed with one end thereof having a threaded hole to engage with the coupling bolt and with the other end closed, and a profile hole smaller than the threaded hole is centrally formed on the closed end. The coupling bolt is formed with a through hole along the central axis thereof to receive an assembly tool to tighten the second nut relative to the coupling bolt. The invention also relates to a method for coupling two shafts with the coupling assembly. With this invention, it is possible to couple two shafts with access to only one side of the shaft flanges.

Abstract: An insert element for closing an opening inside a wall of a hot gas path component of a gas turbine includes a plate like body with an opening sided surface. The surface provides at least one first area which projects beyond at least one second area of said surface which surrounds the at least one first area frame-like. The at least one first area is encompassed by a circumferential edge corresponding in form and size to the opening such that the circumferential edge and the opening contour limit a gap at least in some areas, while the at least one second area contacts directly or indirectly the wall of the hot gas path component at a rear side facing away from the hot gas path. The plate like body provides at least a first functional layer-system, providing at least one layer made of heat resistant material, defining the first area of the surface (S).
