In a flash type evaporator, heated salt water passes through an orifice into an area of lower pressure which is created by an air ejector or vacuum pump. A portion of the water flashes into steam, and the steam passes up to a vapor separator, where water droplets are removed, and then to a distilling condenser where the vapor is condensed .
