Abstract: A fluid compression system is disclosed having a hermetically-sealed housing with at least a motor and a compressor arranged therein. The motor may drive both the compressor and a blower device coupled to the housing or otherwise arranged within the housing and configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings. The blower device circulates the cooling gas through a closed-loop circuit which may include a heat exchanger and gas conditioning skid. Buffer seals may be used to seal the shaft on both sides of the compressor so as to prevent the migration of liquid and solid contaminants into the closed-loop cooling circuit.

Abstract: A method for retrofitting a turbomachine is provided wherein a first trip cup of the turbomachine is replaced with a second trip cup and by replacing a mechanical flyweight governor with a mechanical-hydraulic governor. The second trip cup includes a plunger disposed in a hole defined by the second trip cup. The first trip cup is removed from the turbomachine and the second trip cup installed such that, when a speed of the turbomachine exceeds a predetermined value, the plunger actuates a trip paddle located adjacent the second trip cup. The mechanical flyweight governor is removed from the turbomachine and a first set of governor linkages coupling the mechanical flyweight governor to a steam source. The mechanical-hydraulic governor is installed in the turbomachine, the mechanical-hydraulic governor being coupled to a shaft of the turbomachine and being coupled to the steam source via a second set of governor linkages.

Abstract: A hybrid compressed air energy storage system is provided. A method of operation thereof includes compressing air during a storage period, and extracting thermal energy therefrom to produce a cooled compressed air. The cooled compressed air may be stored in an air storage unit, the extracted thermal energy may be stored in a thermal storage device, and the stored cooled compressed air may be heated with the stored extracted thermal energy to produce a heated compressed air during a generation period. The heated compressed air may be expanded with an expander to generate power and discharge an expanded air, which may be heated with a recuperator to produce a heated expanded air. A fuel mixture including the heated expanded air may be combusted to produce an exhaust gas, which may be expanded with a second expander to generate power and discharge the expanded exhaust gas to the recuperator.

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: An acoustic resonator assembly may include a first acoustic liner and a second acoustic liner. The first acoustic liner may define a first plurality of openings extending between first and second surfaces thereof. The second acoustic liner may be rotatably coupled to the first acoustic liner and at least one of the first acoustic liner and the second acoustic liner may be configured to rotate relative to each other to attenuate one or more frequencies of acoustic energy generated by working fluid flowing past the acoustic resonator assembly. The second acoustic liner may define a second plurality of openings extending between first and second surfaces thereof. A number of degrees of freedom of the acoustic resonator assembly may be varied by rotating the first acoustic liner and/or the second acoustic liner.

Abstract: A system and method for rapid pressurization of a motor compartment and cooling system during a shutdown, a surge, and/or other situations in which the suction pressure significantly varies. A motor/compressor arrangement includes a seal gas system fluidly communicating with the motor compartment via a motor pressurization line, with the outlet of the compressor, and with a shaft seal. A motor pressurization valve is coupled to the motor pressurization line and a controller is configured to open the motor pressurization valve at start-up of the motor-compressor to supply seal gas to the motor compartment and to pressurize the motor compartment when a difference between the seal gas supply pressure and the suction pressure is indicative of the seal gas supply pressure being insufficient.
