    Abstract: System and method for cooling an expander (100) rotor assembly. The system may include an annular body (148) disposed on a rotor disc (128) of the rotor assembly (118). The rotor disc (128) may also include a plurality of rotor blades (140) mounted thereto via respective roots (142). The annular body may define at least one fluid passageway fluidly coupling the roots (142) and the cooling source (112). The annular ring (148) may be configured to prevent mixing of the flue gas (F) with a coolant (C) provided by the cooling source (112) and flowing through the at least one fluid passageway and contacting at least one root (142). The system may also include a plurality of seal members (192, 292), each disposed between respective platforms (146) of adjacent rotor blades (140) and configured to prevent flue gas (F) flowing though the expander (100) from mixing with the coolant (C).

    Abstract translation: 用于冷却膨胀机(100)转子组件的系统和方法。 该系统可以包括设置在转子组件(118)的转子盘(128)上的环形主体(148)。 转子盘(128)还可以包括经由相应的根部(142)安装到其上的多个转子叶片(140)。 环形主体可限定流体地联接根部(142)和冷却源(112)的至少一个流体通道。 环形环(148)可构造成防止烟道气(F)与由冷却源(112)提供的冷却剂(C)混合并流过至少一个流体通道并接触至少一个根部(142 )。 该系统还可以包括多个密封构件(192,292),每个密封构件设置在相邻转子叶片(140)的相应平台(146)之间并且被配置为防止流过膨胀器(100)的烟道气(F)与 冷却液(C)。
