Summary:In one aspect the present subject matter is directed to a system for thermally shielding a portion of a shroud assembly for a gas turbine 14. The system includes a shroud support 80 having a forward wall 92 that includes a front side 96 that is axially spaced from a back side 98 and a radially inner surface 100 that extends axially between the front and back sides. A shroud is mounted to the shroud support. The shroud includes a leading edge portion 102 that extends towards the forward wall of the shroud support and a trailing edge portion 104 that extends towards the aft wall of the shroud support. A radial gap is defined between a top surface of the leading edge portion and the radially inner surface of the forward wall. A thermal shield 110 is disposed along a bottom portion of the forward wall and is oriented to face towards a flow of combustion gases.
