  • Publication number: 20110214431
    Abstract: A turbine guide vane support for an axial-flow gas turbine is provided. The support includes a tubular wall having an inflow-side end and an outflow-side end for a hot gas flowing in the interior of the turbine guide vane support in a flow path of the gas turbine. Cooling channels for a coolant are provided in the wall. The cooling channels extend from a coolant inlet to a coolant outlet, respectively. At least one of the cooling inlets and one of the cooling outlets, respectively, is disposed at the outflow-side end of the turbine guide vane support, wherein the cooling channel associated with the respective inlet and outlet extends up to the inflow-side end of the turbine guide vane support and transitions to a redirecting area from which the respective cooling channel further extends to the outflow-side end.

  • Publication number: 20100300104
    Abstract: A burner incorporating a pilot cone and a mounting insert is provided. The pilot cone is constructed as a pilot cone assembly which is decoupled from the mounting insert. Further, an operating method for increasing the service life of a burner which incorporates a pilot cone assembly and a mounting insert is provided. The pilot cone assembly has a cone side and incorporates at least one further side where the further side is arranged to be essentially parallel to one of the sides of the mounting insert and spaced apart from it, so that between the further side and the side of the mounting insert there is a defined gap. In an operation of the burner, the gap is significantly reduced by the thermal expansion in at least at one point of contact between the further side and the side of the mounting insert. Finally, an assembly method is provided.
