Heat shield configuration, particularly for structural parts of gas turbine plants
First Claim
1. In combination with a supporting structure, a heat shield configuration for protecting the supporting structure against a hot fluid, the heat shield configuration comprising:
- an inner lining formed of a heat-resistant material and having substantially plate-shaped heat-shield elements disposed next to one another with gaps in-between and covering an entire area of the supporting structure, said heat-shield elements formed of an erosion-proof and corrosion-proof material and being resistant to high temperatures;
at least one fastening element anchoring said heat-shield elements thermally movably to the supporting structure;
a thermal insulation disposed between said heat-shield elements and the supporting structure; and
at least one coolant duct having an inlet and an outlet and formed between said heat-shield elements and said thermal insulation, said thermal insulation having a coolant supply duct formed therein connected to said inlet of said at least one coolant duct, said outlet of said at least one coolant duct being open to the hot fluid.

Abstract
A heat shield configuration, particularly for protecting supporting structures and structural parts of gas turbine plants against a hot fluid. The heat shield has an inner lining which consists of a heat-resistant material and which is composed of plate-shaped heat-shield elements resistant to high temperatures and are disposed next to one another with gaps in-between. The heat-shield elements cover the entire area of the structural part. The heat shield is anchored so as to be thermally movable to the supporting structures and parts by bolts. The heat-shield element is formed of an erosion-proof and corrosion-proof material. An insulating brick formed of a refractory ceramic is disposed in each case between each heat-shield element and the supporting structure or parts.
