ABSTRACT:
The invention relates to a heat shield arrangement for a hot gas (m)-guiding component, which comprises a number of heat shield elements arranged side-by-side on a supporting structure while leaving a gap there between. A heat shield element can be mounted on the supporting structure whereby forming an interior space which is delimited in areas by a hot gas wall to be cooled, with an inlet channel for admitting a coolant into the interior space. According to the invention, a coolant discharge channel is provided for the controlled discharge of coolant from the interior space and, from the interior space, leads into the gap. Coolant can be saved and efficiently used by the specific coolant discharge via the coolant discharge channel, and reduction in pollutant emissions can also be achieved. The heat shield arrangement is particularly suited for linking a combustion chamber of a gas turbine.
