A heat exchanger of the shell and tube type having a floating tube sheet to accommodate differential thermal expansion and contraction between the shell and the tubes. The cross-sectional area of sliding joint means between the floating tube sheet and the shell, and the total external and internal cross-sectional areas of the tubes, are selected to minimize axial forces on the tubes. A novel tube support system including hollow support members engaged between the adjacent tubes enables a true counterflow heat exchange relationship to be established between the shell side fluid and the tube side fluid.

A sea thermal power plant is provided with pumps of the propeller type for bringing up cold water and forcing it through suitable condensers or heat exchangers and for drawing a continuous flow of warm water from a surface layer of the sea and forcing it down through suitable heat exchangers or boilers of the plant. The water so drawn from the sea flows through the heat exchangers and is subsequently discharged therefrom, which action creates thrust thereby producing forces to move the plant over the water surface. The heat exchangers are provided with deflectors which control the direction of discharge to produce a reaction force in any desired direction to drive the power plant. The pumps have associated therewith pipes which have located therein, downstream of the pumps, bypass louvres or vanes which can be opened to discharge water directly into the sea to produce a higher thrust for moving or positioning the power plant.

An improved turbopump unit and system for pumping hot geothermal liquids from deep wells to the earth's surface. The unit is of simplified single-shaft construction with reduced net reaction thrust on the shaft. Bearing wear is minimized by using hydrostatic bearings and by supplying lubricating liquid thereto which is taken from an intermediate stage of a centrifugal pump at the surface which supplies motive liquid to the turbine. An arrangement is provided that is operated by pressure of the lubricating liquid for maintaining all thrust-engageable surfaces carried by the shaft out of engagement at start-up and shut-down. Means operated by liquid pressure are provided for sealing the unit to the well casing and also for preventing undue tensile or compressive stresses in the supply conduit for the turbine motive liquid while maintaining an effective seal between the unit and the well casing.

In a turbine driven power generating plant of the type using for example a hydrocarbon or halocarbon as the working fluid operating on or near the surface of an ocean, warm surface water is used as a source of heat for a boiler and cold water pumped from substantial depths is used to condense the working fluid after it has been expanded through the turbine. An auxiliary power source for starting the water pumps of the main system includes a prime mover driving a compressor which in turn supplies a high energy working fluid to a turbine coupled to drive the water pumps. The turbine exhaust after being cooled in a heat exchanger by the cold water pumped from the ocean depths, is returned to the suction side of the compressor.

An evaporator fabricated from a plurality of plates arranged in spaced parallel relation with one another within a housing or casing having inlet and outlet openings. The plates are arranged to define fluid passages for both water and refrigerant with the refrigerant passages having separators positioned therein. The housing is provided with partitions that cooperate with certain of said plates to define water passages which extend in a serpentine manner from the inlet to the outlet, with the inlet communicating with the greater number of water passages that gradually diminish in number from the inlet to the outlet.

Heat energy from hot geothermal fluids supplied by different temperature wells is transferred by heat exchange into a power fluid cycle, preferably of the dual fluid type, at different points in the cycle, which both enables an increase in peak cycle temperature to be achieved and allows more heat energy to be transferred into lower temperature points in the cycle. The result is an increase in the amount of power which can be developed per unit of geothermal fluid supplied.

A two-stage compressor includes an auxiliary compressor that reduces the pressure of the gear section. The auxiliary compressor intake communicates with the gear section and the discharge of the compressor communicates with the inlet to the second stage of the compressor.

An apparatus for expanding a tube or pipe by axially compressing an annular resilient element to cause said element to radially expand into engagement with the inner surface of the tube or pipe. The compressing of the resilient element and its radial expansion is caused by a main piston and cylinder structure which is subjected to fluid under pressure. A secondary or impact piston is provided in the main piston for applying higher stresses to the tube or pipe through the resilient element. The resilient element is interposed between a plurality of spaced annular ring members which constitute guide means therefor.
