Abstract: A gas compressor comprising a drum affixed to a rotating shaft, the drum including a plurality of compression channels between a common pressure zone and an interior surface of the drum distal to an axis of rotation. A static vane return assembly adjacent the compression channels includes vanes extending from an inlet at an outer circumference to the common pressure zone and directing gas into the common pressure zone, either through the vanes or via separate channels or ducts. Fluid inside the rotating drum forms an annular lake that is drawn through the vanes and into the common pressure zone. Fluid is then forced into the compression channels where gas in the fluid is compressed as it travels from the common pressure zone toward the interior surface. The pressurized gas is separated from the liquid prior to leaving the compression channel assembly while the liquid is returned to the lake.

Abstract: The present disclosure provides a device for de-icing an air intake lip of an aircraft turbojet engine nacelle. The de-icing device includes a de-icing circuit in which a heat transfer fluid, working in a two-phase form, circulates. The de-icing circuit includes at least one device for circulating the heat transfer fluid in the de-icing circuit, a system for heating the heat transfer fluid and configured to change the phase of the fluid to a vapor phase, and an inlet conduit that opens into the lip through a rear wall and injects the vapor phase fluid into the lip. The fluid changes phase when it condenses on the front wall of the lip to de-ice the lip.

Abstract: A system includes a turbine system that contains a heat recovery steam generator (HRSG) having a flow path that receives an exhaust gas, and having a fluid path that receives a fluid. The fluid path is adjacent to the flow path such that the fluid is heated by the exhaust gas. The HRSG includes an electrical heater that provides heat to the fluid path during a start-up mode of the HRSG, during a shutdown mode of the HRSG, or both.

Abstract: Methods and systems are provided for heating an engine and generating energy from a common waste heat recovery system. In one example, a method comprises, responsive to a first condition, expanding a working fluid of a waste heat recovery system via an expander to generate electricity, and responsive to a second condition, compressing the working fluid of the waste heat recovery system via the expander to transfer heat to an engine.

Abstract: A steam cycle system includes a heat recovery steam generator (HRSG) which receives exhaust gases, a steam turbine coupled to the HRSG which receives a first steam flow generated by the HRSG, and a condenser which condenses a second steam flow output by the steam turbine. The condenser includes a plurality of heat exchanger tubes, a fan, and a steam collection header. The system includes one or more sensors which measure one or more properties of the steam flow. The system includes a closed-loop controller communicatively coupled to the one or more sensors. The controller receives data from the one or more sensors, determines a flow rate of the second steam flow through the steam header using the one or more sensors, calculates whether the flow rate of the steam is within a threshold, and adjusts one or more operating parameters of the fan.

Abstract: A co-generation process for a regenerator in an FCC system having a reactor and a regenerator includes the steps of introducing flue gas from the regenerator into a heating unit at a first location of the heating unit, and introducing an oxygen/fuel gas mixture into the heating unit at a second location of the heating unit apart from the first location, and combusting the oxygen/fuel gas mixture in the heating unit at the second location to form a hot combustion gas. The process further includes the steps of combining the hot combustion gas and the flue gas at a third location of the heating unit apart from the first location to produce heated flue gas, heating water and/or steam with the heated flue gas to produce a heated steam, and introducing the heated steam into a turbine to extract energy from the heated steam.
