  • Patent number: 7231713
    Abstract: A method of reconditioning a rotating blade (1) with a shroud (8) following the operation in a gas turbine, includes the application of a barrier (14) placed on the edge of the shroud (8) facing the edge of a shroud (8) of an adjacent blade having creep deformation. The barrier (14) prevents hot gas ingestion into a shroud cavity (10). It is pre-fabricated or built-up layer-by-layer by welding or laser cladding or other methods. Additionally, the mass of the shroud (8) is reduced in order to re-establish the initial mass of the shroud. A thermal barrier coating (15) is additionally applied to the surfaces of the shroud (8) that are exposed to the hot gas of the turbine. The method significantly increases the lifetime of the blade (1).

  • Patent number: 7216486
    Abstract: Relevant fuel-gas properties (XG) are measured on an ongoing basis while a gas turbine group is operating. The C2+alkane content of the fuel gas is of particular interest in this context, since it has a significant influence on the ignitability of the fuel gas in the combustion chamber. The operating parameters of the gas turbine group are acted on directly as a function of the measured fuel-gas properties. In particular, in the case of the example of a gas turbine group with sequential combustion, the distribution of the fuel mass flows ({dot over (m)}EV, {dot over (m)}SEV) between the combustion chambers (4, 8) of the gas turbine group is varied. Furthermore, if there is provision for inert media, such as water or steam, to be introduced, it is possible for the mass flow of inert media ({dot over (m)}ST) to be controlled as a function of the measured fuel properties.
