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. |
