摘要：

In a turbine having closed-circuit steam-cooling passages (54,56) about the rim of the rotor (R) during steady-state operation, compressor discharge air is supplied (54) to the rotor bore for passage radially outwardly into the wheel space cavities (C) between the wheels (38,40,42,44) and spacers (39,41,43). Communicating slots and channels in the spacers and wheels at circumferentially spaced positions enable egress of the compressor discharge air into the hot gas flow path. At turbine startup, cooling air flows through the closed-circuit steam passages to cool the outer rim of the rotor while compressor discharge air pre-warms the wheels and spacers. At steady-state, cooling steam is supplied in the closed-circuit steam-cooling passages and compressor discharge air is supplied through the bore and into the wheel space cavities to cool the rotor.

摘要（中）：

在稳态运行期间，具有围绕转子（R）的边缘的闭路蒸汽冷却通道（54,56）的涡轮机将压缩机排放空气（54）供应到转子孔，用于径向向外通向轮子 车轮（38,40,42,44）和间隔件（39,41,43）之间的空间腔（C）。 在间隔件和车轮上沿周向间隔开的位置沟通槽和通道可使压缩机排出空气流入热气流动路径。 在涡轮机启动时，冷却空气流过闭路蒸汽通道，以冷却转子的外缘，同时压缩机排出的空气预热了车轮和间隔件。 在稳定状态下，在闭路蒸汽冷却通道中供应冷却蒸汽，压缩机排出的空气通过孔被供给到车轮空间以冷却转子。
