Gas turbine power augmentation method

ActiveUS20060070383A1High power outputIncrease powerHydrogenGas turbine plantsHydrogenCombustor

A power augmentation method for a gas turbine in which water is injected into one or more stages of an auxiliary compressor to produce a vapor containing gas stream. The vapor containing gas stream is at least in part introduced into combustors of the gas turbine for power augmentation. Part of the vapor containing compressed gas stream can be introduced into a reactor to generate a hydrogen containing synthesis gas to support lower flame temperatures occurring within the combustors of the gas turbine due to the introduction of the vapor containing gas stream. In such manner, NOx emissions of the gas turbine can be reduced. Furthermore, the power augmentation method can be conducted in conjunction with an integrated gasification combined cycle.

A water heater with two non-condensing flues and a condensing flue(s) having a system to prevent condensation in the non-condensing flue(s). The downwardly extending first flue is connected by a 180 degree connector to an upwardly extending second flue. Between the non-condensing and the condensing flues is positioned a temperature sensor. A controller receives input from the temperature sensor and is connected to the burner to control the minimum power setting and duration so as to prevent the combustion gases from falling below a temperature at which water will condense at the temperature sensor so no condensation occurs in the first two flues. Burner power settings are minimized near a water tank setpoint to improve efficiency by increasing condensation.

The present invention provides a fuel stack comprising: a plurality of fuel cell units stacked together in a direction of stacking each of which comprises an electrolyte element, a pair of electrodes holding the electrolyte element therebetween, and a pair of separators holding the electrodes therebetween; a pair of terminal plates each of which is disposed outside an end fuel cell unit located at an end of the stacked fuel cell units; and a terminal element extending outwardly in the direction of stacking from the outside surface of at least one of the terminal plates; wherein the location from which the terminal element extends is located within an area on the terminal plate, corresponding to an area in a passage for an oxidizing gas formed in the end fuel cell unit disposed adjacent to the terminal element where the partial pressure of water vapor is lower than the saturated water vapor pressure. More preferably, the terminal element is disposed as close to the centerline of the terminal plate as possible so that the total electrical resistance of the terminal element and the terminal plate is minimized. By this configuration, an increase in the total electrical resistance and water vapor condensation in the fuel cell units located at the ends of the stack may be prevented.

A reservoir unit (200) is provided comprising a housing (201) in which a reservoir (250) with a transparent portion (251) is arranged, the housing comprising a window (203) allowing a portion of the reservoir to be inspected. The reservoir unit is adapted to be moved from a first “cold” condition to a second “warm” condition with no visible water condensing on the interior surface of the window portion. Further, a vent (210, 211) is adapted to provide pressure equalization between the interior of the housing and the exterior. In this way it is possible to perform visual inspection of the reservoir at all times without being confused by dew or condensed water drops, e.g. when a prefilled reservoir unit containing a drug which requires storage at a given low temperature, as is the case for insulin-containing drugs, is taken out in ambient temperature.
