Thermally stressable wall and method for sealing a gap in a thermally stressed wall

摘要

The invention relates to a wall (21) which can be thermally impinged upon by a hot gas (17). A gap (55) is created between a first segment (35) and a second segment (33) of the wall by deforming a bending element (45) of the second wall segment (33) at high temperatures. The bending element (45) is pressed against a pressing surface (49) of the first segment (35) of the wall. Deformation is caused by different types of thermal expansion of a hot and cold side of the bending element (45), whereby the gap (55) is sealed in a highly effective manner even at high temperatures.
