摘要:
A heat shield element arrangement including a heat shield element for a heat shield arranged on a supporting structure is provided. On each of the two opposing sides running parallel to the installation grooves the heat shield element includes a continuous screw head opening which penetrates the cold side and the hot side of the heat shield element substantially vertically and through which the screw head of the respective screw is arranged to be accessible to the supporting structure, and a spring element may be arranged under the respective screw, which spring element may be extended along the hot side of the heat shield element and the parallel installation groove of the supporting structure. An outer end of the spring element is embodied as a clamping retaining hook which is provided for the purpose of engaging in the laterally recessed retaining groove of the heat shield element.

摘要:
Disclosed is a molding compound for producing a fireproof lining, especially for a combustion chamber of a stationary gas turbine. The molding compound is characterized particularly by the fact that the molding compound is formed from more than about 50 percent by weight of silicon carbide and less than about 50 percent by weight of aluminum silicate.
摘要:
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.
摘要:
The aim of the invention is to provide a highly durable, high-strength thermal shield element 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.

摘要:
The invention relates to a combustion chamber wall in a combustion chamber, comprising a support structure with a number of heat shield which are attached to the support structure with the aid of a fastening means. Said fastening means encompasses a spring device which is fixedly connected to the support structure and is composed at least of a spring that is mounted in a jacket. The spring is secured against falling out on the side facing away from the combustion chamber by means of a first removable retainer. The interior of the spring device is provided with an axial hole for accommodating the fastening means. The spring is secured against falling out on the side facing the combustion chamber by means of a second removable retainer. The spring device can be dismounted on the side facing the combustion chamber.
摘要:
An article comprising a ceramic material having a ceramic matrix composite backing adapted for use in a gas turbine engine is provided. The article comprises a structural ceramic material having a hot side facing toward a high temperature environment and a cold side facing away from the high temperature environment; and a ceramic matrix composite composition having a strength greater than the strength of the ceramic material attached to the back of the cold side of the ceramic material, whereby crack initiation and propagation are inhibited by the ceramic matrix composition to a greater degree than by the ceramic material.
摘要:
A retaining element for retaining a heat shield element on a support structure comprises at least one fixing section adapted to fix the retaining element to the support structure and at least one retaining section adapted to engage with an engaging groove present on a periphery of the heat shield element. A projection is arranged on the retaining element in such a manner that it projects in the direction of the heat shield element when retaining a heat shield element.
