Abstract: A pumped heat energy storage (PHES) system (100) including a charging circuit and a discharging circuit effective to balance or split a total heat rejection of the PHES system between the charging circuit and the discharging circuit. The charging circuit may include thermal storage vessels (102, 104) to store thermal energy generated from a first compressor (110). A first heat rejection system (128) is fluidly coupled with the thermal storage vessels to remove thermal energy from the charging circuit. The discharging circuit may include a first turbine (146) fluidly coupled with the thermal storage vessels to extract thermal energy stored in the thermal storage vessels and convert the thermal energy to mechanical energy via an expansion of a second working fluid. A second heat rejection system (156) is fluidly coupled with the thermal storage vessels and the first turbine to remove thermal energy from the discharging circuit.

Abstract: A compressor may include a casing defining a discharge cavity and a seal cavity. A rotary shaft may be disposed in the casing, and a shaft seal assembly may be disposed in the seal cavity and about the rotary shaft. An impeller may be coupled with and configured to be driven by the rotary shaft. A balance piston may be integral with the impeller and may define the discharge cavity and the seal cavity. A balance piston seal may be disposed about the balance piston such that the balance piston seal and the balance piston define a radial clearance therebetween. The radial clearance may be configured to provide fluid communication from the impeller to the discharge cavity. A heat shield may be disposed in the discharge cavity, and may be configured to prevent the conduction of heat from the discharge cavity to the seal cavity via the casing.

Abstract: A seal assembly is disclosed that can be used to seal a bearing case in a turbine. The seal assembly has an annular seal plate seated within a groove defined in the bearing case and radially-offset from the turbine shaft. A seal retainer is mounted on the shaft axially-offset from the annular seal plate and defines a channel therein for receiving and seating a seal therein. The seal has a flexible lip that extends from the body of the seal and engages either the inside surface of the bearing case or a counterface of the annular seal plate, thereby preventing or substantially restricting the influx of contaminants into the bearing case.

Abstract: Systems and methods for cooling one or more components of a gas turbine are provided. One system may include an expansion device and one or more conduits. The expansion device may be operatively coupled to the gas turbine and configured to convert a pressure drop of a stream of compressed process fluid to mechanical energy. The expansion device may be further configured to at least partially drive the gas turbine with the mechanical energy. The one or more conduits may fluidly couple the expansion device and the gas turbine. The one or more conduits may be configured to direct an expanded stream of the compressed process fluid to the one or more components of the gas turbine to cool the one or more components.

Abstract: A seal assembly for a dual-flow compressor is provided. The seal assembly may include an annular body disposed about a rotary shaft between a first compression assembly and a second compression assembly of the dual-flow compressor. An inner radial surface of the annular body and an outer radial surface of the rotary shaft may at least partially define a radial clearance therebetween. The annular body may have a first seal section and a second seal section at a first axial end portion and a second axial end portion thereof, respectively. The first and second seal sections may at least partially define a cavity therebetween. The seal assembly may also include a reference line communicably coupling the cavity with an inlet of the first compression assembly and configured to at least partially generate a pressure differential between the cavity and an outlet of the first compression assembly.

Abstract: An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.
