  • Patent number: 6240718
    Abstract: A combination power station with power/heat cogeneration. The combination power station includes at least one gas turbine driven by combustion gases from a combustion chamber and at least one steam turbine working in a water/steam circuit. The water/steam circuit converts water into steam in a first apparatus by hot combustion gases emerging from the at least one gas turbine. The steam is supplied to the at least one steam turbine. A separate heat transfer medium is arranged in a heat exchange relationship with a heat consumer and is heated in a second apparatus by thermal energy extracted from the water/steam circuit at a plurality of extraction points each having a different temperature. The combination power station includes means for selectively connecting the second apparatus to the plurality of extraction points depending upon a thermal output and an inlet temperature required by the heat consumer.

  • Patent number: 6142665
    Abstract: In a temperature-measuring device, in particular for measuring the flame temperature in a gas turbine combustion chamber, a number of optical measuring sensors (7) are arranged directly upstream of a flame front (8) in a premixing zone (3) of a burner (1). Each optical measuring sensor (7) is aligned essentially parallel to and/or coaxial with a fuel flow (5) directed into the gas turbine combustion chamber.
