    Abstract: A magnetic bearing is disclosed that includes a sensing wire wrapped around one or more of the bearing coils and configured to measure the resistance to ground of each bearing coil. With the presence of contaminants such as liquids, a protective coating disposed about the bearing coils degrades over time, thereby reducing the resistance to ground of the bearing coils. The sensing wire transmits the detected resistance to ground of the bearing coils to an adjacent sensing device, which can provide an output that informs a user whether corrective action is required to prevent damage or failure of the magnetic bearing.

    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: A turbine (10) includes a disk (25) having a plurality of protrusions (120) arranged such that any two adjacent protrusions (120) define an axial entry fir tree space (125), each protrusion (120) defining an outermost lobe (165) having an outermost surface (150) and an axial length. A turbine blade (30) includes an airfoil (170), a platform (175), and a blade root (180) having a fir tree arranged to engage a leading protrusion (135) and a trailing protrusion (140). The blade root (180) and the leading protrusion (135) cooperate to define a leading gap (200), and the blade root (180) and the trailing protrusion (140) cooperate to define a trailing gap (215). A leading plug (220) is disposed in the leading gap (200) and a trailing plug (225) is disposed in the trailing gap (215). Each of the leading plug (220) and the trailing plug (225) have a plug (220) length that is at least as great as the axial length.
