A hydrogen cooled generator having a system for diagnosing problems associated with a seal oil system. Included is a shaft having a turbine end and a collector end; a first shaft seal located about the shaft at the turbine end; a second shaft seal located about the shaft at the collector end; a first set of sensors for measuring seal oil pressure differentials across both shaft seals; a second set of sensors for measuring seal oil temperature differentials across both shaft seals; a third sensor for measuring a hydrogen side seal oil flow rate; and a system for analyzing data collected from at least two sensors to diagnose the shaft seals.

Turbine-generator hydrogen seal oil system diagnosis

In one embodiment, the invention provides a lubrication system for a machine comprising: a direct current (DC) motor; a battery system for powering the DC motor; a lubricating system in communication with the DC motor, the lubricating system including a supply of lubricating oil and a pump for delivering the lubricating oil to at least one component of the machine requiring lubrication; a hydraulic motor operably coupled to a shaft of the DC motor; a supply of a pressurized fluid in communication with the hydraulic motor; and a control device for discharging the supply of pressurized fluid into the hydraulic motor to power the hydraulic motor, whereby the hydraulic motor, when powered by the supply of pressurized fluid, is operable to turn the shaft of the DC motor, thereby reducing an operating current supplied to the DC motor by the battery system.

Hydraulic-assisted lubrication system and method

Systems for controlling hydrogen purity in a power plant system are disclosed. In one embodiment, a hydrogen control system for a generator housing includes: a mass flow control system fluidly connected to the generator housing, the mass flow control system being configured to measure a flow rate of a gas mixture extracted from the generator housing and modify the flow rate of the gas mixture across a range of flow rates; and a vent conduit fluidly connected to the mass flow control system, the vent conduit for receiving a portion of the gas mixture from the mass flow control system and feeding the portion of the gas mixture to an outlet.

Hydrogen control system for electric generator

A hydrogen cooled generator includes a lubricant drain system. The lubricant drain system includes a hydrogen detraining tank having a hollow interior portion. A sensor is operatively mounted in the hydrogen detraining tank. The sensor is configured and disposed to detect an interface zone between an amount of lubricant and an amount of hydrogen gas in the hollow interior portion. A drain line is fluidly coupled to the hydrogen detraining tank. The drain line includes a first end portion that is exposed in the hollow interior portion and a second end portion. A valve is mounted in the drain line. A controller is operatively connected to the sensor and the valve. The controller is configured to selectively open the valve allowing a portion of the amount of lubricant to flow from the hollow interior portion when the interface zone is above the first end portion of the drain line.

Hydrogen cooled generator lubricant drain system

A system for cooling at least one gas turbine liquid fuel component located in a high temperature environment to eliminate coking in the component is disclosed. The system includes a sleeve surrounding the liquid fuel component, a device for providing a current of cool air, and a conduit connected between the cool air device and the sleeve to direct the current of cool air into the sleeve to cool the liquid fuel component. The system can also include a manifold connected to the conduit and a plurality of second conduits for connecting the manifold to a plurality of sleeves surrounding a plurality of liquid fuel components, each sleeve being connected to a corresponding second conduit. Each sleeve includes a plurality of spacing devices for centering the sleeve around the at least one liquid fuel component so as to form an annulus between the sleeve and the liquid fuel component through which the current of cool air flows. The system can alternatively use a supply of cool liquid pumped by a pump through a conduit adjacent to a liquid fuel component to cool the component.

Cooling of liquid fuel components to eliminate coking

A recirculation system for circulating distillate during gas fuel operation so as to reduce or eliminate distillate carbon formation. The recirculation system keeps the distillate's temperature below the carbon formation limit by circulating the distillate back to a heat sink and/or heat exchanger. The recirculating flow also exercises the flow dividers' gears without having to perform fuel transfers. Further, the system evacuates air from the liquid fuel lines to further decrease the likelihood of carbonaceous residue forming on any interior surfaces that are actually exposed to distillate.
