  • Publication number: 20160360656
    Abstract: A mounting arrangement for mounting a device in an opening is disclosed. The arrangement comprises an outer sleeve, an inner sleeve arranged inside the outer sleeve, and an adjustment ring arranged inside the outer sleeve. A flange is arranged at a first end of the outer sleeve, arranged to receive said device. The flange is adapted to abut an outer surface of the structure. The inner sleeve is arranged in threaded engagement with the adjustment ring or with the outer sleeve. The adjustment ring comprises a fixing wing extending outwardly through a longitudinally extending aperture in the outer sleeve, the fixing wing having an abutment portion adapted to abut an inner surface of the structure. By relative rotary motion of the inner and outer sleeve, the adjustment ring is movable along a longitudinal direction of the arrangement for adjustment to a thickness of the structure.

  • Patent number: 9181871
    Abstract: The present invention relates to an indirectly heated gas turbine system comprising a combustion chamber (3) that extends along a central axis of the gas turbine system for the combustion of compressed air and supplied fuel whereby flue gas is formed, a turbine (2) driven by a working medium, a compressor (1) rotatably connected to the turbine for compressing the working medium and/or air to the combustion chamber, and a first heat exchanger device (8) for the transfer of heat between the flue gas and the working medium. The first heat exchanger device and the combustion chamber are integrally formed as a monolithic unit, the first heat exchanger device being substantially arranged within the axial extension of the combustion chamber along the central axis. By the integrated design of the combustion chamber and the first heat exchanger device, a compact, indirectly heated gas turbine system having high efficiency is achieved.

  • Publication number: 20150184870
    Abstract: A system comprising a water tank, a heat source, which is external of the water tank, a first conduit and a second conduit and further conduits for connection of the water tank with a user. In a discharge mode of operation, water flows through the first conduit to a user only from the upper portion of the tank. Return water flows through the heat source and further to the second conduit and into the lower portion of the tank. In a charge mode of operation of the system, no water flows to the user and no return water is introduced in the system. A pump is operated to remove colder water from the lower portion of the tank via the second conduit and pass the water to the heat source and back to the upper portion of the tank via the first conduit. The system further comprises a five-port valve for switching the operation from charging and discharging and vice versa based on a water flow into or out of the system.
