Abstract: A distributor of flowable medium for a heat exchanger has a housing member and at least one substantially vertically oriented tube member arranged therein. The distributor has a hollow body arranged to be supported in one end of the tube member. An upturned funnel shaped core member is formed in the hollow body, resulting in an annular flow passage between the body and the core member. The body has an upper section with an inlet, a lower section with an outlet, and a mid section between the upper and lower sections. The flow passage extends from the inlet to the outlet at the lower section, and is configured to narrow progressively from the inlet towards the mid section, and widen progressively from the mid section towards the outlet for modifying flow characteristics of the medium flowing through the passage. Intake guide elements are provided at the upper section.

Abstract: A system for distilling sea or brackish water includes a feed water arrangement for supplying feed water from a feed water source to one or more flashing stages. Each flashing stage has a water flash evaporator for vaporizing at least part of the water therein, and a condenser for receiving the vapour and converting at least a part of the vapour into distilled water. A heat storage arrangement provided with a heat generating source for storing heat energy is used to heat a fluid medium flowing through it. A heat exchange arrangement receives the hot fluid medium and transfers heat to a stream of vapour flowing under pressure from each flashing stage. The vapour leaving the heat exchange arrangement being at a raised temperature is arranged to be condensed into water at the condenser and to transfer some of its latent heat to the evaporator.

Abstract: A distillation system is provided for recovering water from sea water and other polluted water source. The system has a heat engine embodying Carnot cycle and a Rankine cycle formed by heat exchangers, flash evaporator and condenser. Burnt gases from the engine such as a jet engine no longer fit for flying are directed into a duct where the exchangers are located. Sea water is pumped into the heat exchanger for preheating by residue heat in the duct and then into the exchanger for further heating. A recirculating pump raises water pressure in the exchanger for increasing boiling point to about 165° C. The heated water is fed into the evaporator where it changes into vapour and condensed into water by the condenser. The jet air stream is used to create Venturi effect for maintaining sub-atmospheric pressure in the evaporator. Any solid left in the evaporator is removed by a transfer mechanism.
