Abstract: A combined water purification and power generating plant is disclosed having special features designed to maximize the cycle thermal efficiency and salt recovery, with little or no concentrated brine produced therefrom. Using the plant, a volume of salt water is delivered to a plurality of indirect and direct contact feed heaters. Within the direct contact heaters, the salt water is heated and diluted by condensation therein by super-heated steam delivered thereto. Any alkaline salts having reverse solubility characteristics particulate and are filtered therefrom. From the last direct contact feed heater, the diluted salt water is delivered to a plurality of high pressure, high temperature evaporators arranged in a series which are used to further heat, evaporate and filter the salt water in multiple stages thereby improving the plant's efficiency. A steam heater is used to super-heat a steam which delivered to various areas of the plant to heat and evaporate the salt water.
