  • Patent number: 7805945
    Abstract: A highly durable, high-strength thermal shield element is provided for the interior lining of the combustion chamber of a gas turbine. For this purpose, the thermal shield element comprises a base produced from a solidified cast ceramic material into which a plurality of reinforcing elements are integrated, to increase the tensile strength of the thermal shield element.

  • Patent number: 7793503
    Abstract: The invention relates to a heat shield block, particularly for lining a combustion chamber wall, with a hot side that can be subjected to the action of hot medium and with a wall side situated opposite the hot side. A core area, which has a core material, extends inside the heat shield block from the hot side to the wall side. The core area is surrounded by an edge area with an edge material whose heat conductivity is lower than that of the core material. This targeted thermal insulation in the edge area provided in the form of a material bond between the core material and the edge material renders the heat shield block particularly unsusceptible to the formation and growth of cracks in the core area on the hot side. The invention also relates to a combustion chamber provided with heat shield blocks of the aforementioned type, and to a gas turbine provided with a combustion chamber comprising such a heat shield block.

  • Publication number: 20100213645
    Abstract: There is described a heat shield element comprising a hot side which is turned towards the hot medium, a cold side which is turned away from the hot medium, peripheral sides which connect the hot side to the cold side and a material volume which is defined by the hot side, the cold side and the peripheral sides, wherein the material volume comprises at least two material areas which are made of different materials. The materials are different from each other at least in respect of their resistance and/or thermal expansion coefficient.

  • Publication number: 20080104963
    Abstract: Disclosed is a thermal shield element comprising a hot side that is to face a hot medium, a cold side which is to face away from the hot medium, circumferential areas that connect the hot side to the cold side, and a material volume which is delimited by the hot side, the cold side, and the circumferential areas. The inventive thermal shield element is characterized in that the material volume encompasses at least two material zones which differ regarding the thermal expansion coefficient thereof.

  • Patent number: 7306194
    Abstract: A mold for producing a ceramic heat shield element having a mold shell is provided. The mold shell comprises a plurality of mold surfaces and a casting aperture for pouring in a ceramic material. The mold shell is embodied as a single-piece mold shell during casting, and the casting aperture is embodied as an aperture in one of the mold surfaces. Separating or retaining elements enable graded or reinforced heat shield elements to be produced.
