SPLIT RING COOLING STRUCTURE AND GAS TURBINE |
摘要 |
A split ring cooling structure for cooling split rings of a gas turbine, the cooling split rings being formed of a plurality of split bodies arranged in the circumferential direction to form an annular shape and being arranged in the comportment so that the inner circumferential surface keeps a fixed distance from the tip of a turbine rotor blade. The split ring cooling structure includes a collision plate provided with a plurality of small holes, a cooling space surrounded by the collision plate and the split bodies, a first cavity arranged at the upstream side end of the split bodies in the flow direction of combustion gas perpendicularly to the axial direction of the rotating shaft, a first cooling channel communicating with the first cavity from the cooling space, and a second cooling channel communicating from the first cavity with the combustion gas space at the downstream side end of the split bodies in the flow direction of combustion gas. |
