A liner cooling device for cooling a liner of a gas turbine is provided. The liner cooling device may include a support portion disposed between a liner and a transition piece of a gas turbine and configured to include a cooling flow passage through which cooling air moves to the transition piece. The support portion includes a support member disposed between the liner and the transition piece and an auxiliary support member disposed in the cooling flow passage and having a hole through which the cooling air passes.

A transition piece assembly improves the cooling of a transition piece by increasing a flow of compressed air toward a transition piece casing. The assembly includes a transition piece including an inlet and an outlet; a transition piece casing spaced apart from the transition piece, the transition piece casing enclosing the transition piece to form an annular interspace between an inner circumferential surface of the transition piece casing and an outer circumferential surface of the transition piece, the transition piece casing including an outer circumferential surface over which compressed air flows; a support member for supporting the transition piece casing, the support member inserted into the annular interspace and seated on the outer circumferential surface of the transition piece; and a guide member that is fixed with respect to the transition piece casing and includes an axially perpendicular structure to guide the compressed air toward the transition piece casing.
