Abstract: A baffle for improving coolant gas flow distribution in the gap region of a gas cooled dynamoelectric comprises a perforate member defining at least one gas flow path therethrough. The baffle preferably is spaced from the arcuately surrounds the rotor of the generator, wherein the gas flow path provides communication between the end space region and gap region of the generator. The member may define a plurality of gas flow paths disposed in a predetermined array. Gas exiting the gas flow paths may be directed from substantially parallel to the axis of rotation of the generator to an outwardly radial angle of about 30.degree. with respect to the axis of rotation. The size, spacing and disposition of the gas flow paths are coordinated with circumferential gas flow paths around the baffle to provide rapidly radially diffused coolant gas flow downstream the baffle, thus ensuring adequate coolant gas flow to stator core coolant ducts of the generator.

Abstract: An integrated coal-fired gas turbine power plant includes a hydraulic compressor for providing pressurized air to a coal combustion system and cooling air to the gas turbine. The power plant may further include a regenerator between the compressor and the combustion system, and a gas cleanup segment between the combustion system and the gas turbine.

Abstract: An improved arrangement for feeding a cool liquid into a pressure vessel and mixing the fed liquid with hot liquid contained therein includes a flow-shielding ejector thermal sleeve disposed partially within an inlet nozzle and surrounding a supply line through which the main feed flow is conducted to a sparger outlet port in the vessel. The sleeve is spaced radially inwardly from the inner surface of the nozzle to define a generally annular flow-through space therebetween. Cool leakage liquid flow is confined within the sleeve and ejected by the main feed flow from an ejector chamber formed around the port by a downstream portion of the sleeve. The ejective action of the main flow exiting the port additionally draws an insulating flow of hot liquid from the vessel sequentially upstream through the flow-through space, into the interior of the upstream portion of the sleeve, and downstream with the confined cool leakage flow, thereby substantially reducing cracking of the nozzle.
