A brush ring seal device for installation within a packing case of a turbine includes: a brush seal carrier having a substantially ring-shaped body portion having a front face, a rear face, an inner circumferential groove, and an outer circumferential groove; a brush seal mounted within the inner circumferential groove of the brush seal carrier; and a ring-shaped spring mounted within the outer circumferential groove of the brush seal carrier. The rear face of the brush seal carrier is coated with an anti-friction coating, thereby allowing movement of the brush ring seal device within the packing case.

A method for casting a diafram having inner and outer rings with preformed vanes circumferentially spaced therebetween is disclosed. A digital representation of a sand core is created. Based on this digital representation, a sand core is produced by bonding together successive layers of sand with droplets of a binder material using a binder printhead having nozzles for supplying jets of binder material droplets. A plurality of vanes is inserted into the cavities of the sand core. The sand core is then placed into a casting mold and filled with liquid metal. After the liquid metal has solidified and cooled, the sand core and any remaining sand is removed from the cast diafram.

An apparatus for exercising an emergency shutoff valve of a steam turbine and methods for operating the same are disclosed herein. A cover of the valve exerciser mounts on top of an emergency shutoff valve body and through a stroker bolt threadingly engaged with the shutoff valve lever arm, the valve stem is moved within a passageway of the cover a small amount so that the aperture between the steam inlet and outlet is not blocked, thereby permitting normal operation of the steam valve while the valve stem is exercised.
