Abstract
A process for vaporizing liquid water which allows the use of relatively impure boiler feed water comprising providing a heat-carrying liquid at a predetermined elevated temperature to the boiler, providing liquid water to the boiler, transferring heat from the heat-carrying liquid directly to the liquid water to be vaporized within the boiler and separately withdrawing the produced steam from the boiler. Suitable heat-carrying liquids include lead, tin and bismuth and alloys principally thereof. A process for the production of superheated steam from natural waters which have not been previously purified utilizing the above described process for production of steam in combination with a process for superheating the steam by passing the produced steam in heat exchange relation with a plurality of liquid droplets of molten metal or a molten inorganic salt which has been heated to a predetermined temperature for superheating the steam.
