Abstract:
1. A heat shield arrangement for a hot-gas conducting structure, comprising: a support structure; a first heat shield element having a groove arranged toward a surface of the first heat shield element that faces the hot gas and is anchored to the support structure; a third heat shield element having a groove arranged toward a surface of the third heat shield element that faces the hot gas and arranged non-adjacent to the first heat shield element and anchored to the support structure; a second heat shield element arranged between to the first heat shield element and the third heat shield element and having a groove arranged toward a surface of the second heat shield element that faces the hot gas; a first seal element arranged in the groove of the first heat shield element and connecting the first heat shield element with the second heat shield element, the first seal element and the groove contoured and dimensioned such that the first seal element is adapted to be swiveled from an open position to a closed position through an intermediary position in the groove during movement of the second heat shield element vertically; and a second seal element arranged in the groove of the third heat shield element and connecting the third heat shield element with the second heat shield element, the second seal element and the groove contoured and dimensioned such that the second seal element is adapted to be swiveled from an open position to a closed position through the intermediary position in the groove during movement of the second heat shield element vertically, wherein in the open position the first and second seal elements are not connected with the second heat shield element, in the intermediary position the first and second seal elements are connected with the second heat shield element and the second heat shield element is spaced from the support structure, and in the closed position the first and second seal elements are engaged with the second heat shield element.
