Abstract:
1. A heat shield for use in a gas turbine, comprising: a support structure that extends in a peripheral and axial direction; a plurality of heat shield elements arranged on the support structure abutting each other in a peripheral and axial directions of the supporting structure and having an axial gap and a peripheral gap between the heat shield elements; a plurality of first sealing elements, disposed between the heat shield elements, that seal the peripheral gaps; a plurality of second sealing elements, disposed between the support structure and the heat shield elements, that seal the axial gaps, wherein the second sealing elements that seal the axial gaps are at a different distance from the support structure than the first sealing elements that seal the peripheral gaps; and a plurality of first element retainers securing the heat shield elements to the support structure in the peripheral direction of the support structure; and a plurality of second element retainers securing the heat shield elements to the support structure in the axial direction of the support structure, the second element retainers configured to also retain the second sealing elements in the axial gaps.
