An inlet screen for an ocean thermal power plant has an outer side parallel to the ocean current and a plurality of parallel bars extending at an acute angle to the horizontal, wherein the acute angle opens toward the upstream direction of the current. The total area of through openings in the inlet screen receive the predetermined flow requirement of the power plant at a velocity no greater than 0.5 feet per second, so that fish are not sucked against the screen. The vertical spacing between the bars is no greater than one-half of the inner diameter of tubes in heat exchangers in the plant. The spacing between bars is at a minimum at the outer side of the screen, and the spacing increases between the outer side and the inner side, so that objects do not become wedged between the bars. The inlet screen extends sufficiently below the ocean level to accommodate the plant's water flow requirement at a velocity of no greater than 0.5 feet per second, and extends sufficiently above the ocean level to dissipate the energy of ocean waves as they strike walls of the plant, so that the total form of the waves on the plant is reduced.

A plurality of sealed tubes, pipes or the like constituting the wall of a relatively large diameter pipe that is susceptible of being submerged and which has buoyant or semibuoyant walls. The tubes or pipes are arranged parallel to one another in a circular pattern with their axes parallel to the axis of the large diameter pipe and said tubes are sealed to one another along their length. A suitable clamping device is positioned upon said tubes or pipes to prevent them from collapsing over each other which acts as a positive stabilizer while maintaining said tubes or pipes in alignment in a circle.

Apparatus for deaerating a stream of warm surface sea water for removing a portion of the gases from the water prior to its entry into a heat exchanger or boiler. The gases, such as oxygen, can be removed by subjecting the warm surface sea water to a vacuum after which the water, having been collected at a plurality of sources, is fed in separate passageways to a common plenum chamber from where the water is discharged through the passages of the boiler or heat exchanger into the ocean.
摘要:
A heat exchanger fabricated from a plurality of plates arranged in spaced parallel relation with one another as a stack or assembly that is positioned between pressure plates. The stack of plates are arranged to define fluid and vapor passages with the entire assembly, including cover members, being held together by suitable clamp plates. A flow control element is positioned in the exchanger to control the flow of the incoming liquid, as well as any recirculating liquid, in the delivery of said liquid to the boiling passages.
摘要:
A heat exchanger fabricated from a plurality of plates arranged in spaced parallel relation with one another and assembled as a stack between pressure plates. The assembled stack of plates have top, bottom, and side cover members with one of the side covers having a liquid inlet and a vapor outlet. The liquid inlet is provided with a float control nozzle mechanism, that under certain conditions, will restrict or limit the flow of liquid to the plate members.

The invention relates to an intercooled gas turbine having at least two air compression stages, and at least one nozzle for supplying a liquid coolant to air travelling between the at least two air compression stages. The invention also relates to a method for intercooling a gas turbine having at least two compression stages in which a liquid coolant is supplied to air travelling between the at least two compression stages, whereby the liquid coolant cools the air.

The invention relates to a method for preventing ice from forming on a cooling system for air by adding an antifreeze to the air being cooled by the cooling system. The cooled air containing the antifreeze is then transferred a turbine engine, wherein the air and antifreeze are burned in the turbine engine. A condensed water and antifreeze mixture is also burned in the turbine engine. The invention also relates to an apparatus for preventing ice from forming on the refrigeration system for cooling air. The apparatus includes a sprayer for spraying the antifreeze onto the refrigeration system and/or the air being cooled by the refrigeration system, a collector for collecting a condensed water and antifreeze mixture, and a pump or transferring means for transferring the condensed water and antifreeze mixture to the turbine engine, where the antifreeze and condensed water mixture is burned.

In a centrifugal compressor the drive shaft of the compressor is driven by a step up gear mechanism including an input shaft driving a central drive gear, an output gear mounted on the compressor drive shaft, and three gear trains extending from the central drive gear and the output gear. Two impellers to provide two stages of compression are mounted back to back on the inner end of the compressor drive shaft. The input shaft of the gear train mechanism comprises a quill shaft surrounded by a hollow shaft fixed by friction to the inner end of the quill shaft. A rubbing seal is provided between the outer end of the hollow shaft and the compressor casing. The compressor drive shaft is supported on its outer end by the gear train mechanisms and at its middle and near its inner end by angular contact ball bearings. The portion of the compressor drive shaft between the ball bearing at the middle of the shaft and the outer end of the drive shaft is a flexible quill shaft.
