Abstract
A steam generator having two vaporization chambers filled with molten metal salts for sequential flash evaporation of preheated atomized water through multiple vaporization tubes in said respective chambers. The molten metal salts are heated by secondary solar thermal input from lens assemblies and primary heat input from U-shaped hot air heating tubes within said vaporization chambers supplied by gas fired tube burners. Steam vapor generated by initial vaporization chamber is re-circulated to the secondary chamber outputting super heated steam. The molten metal vaporization chambers are encased in a single pressure vessel with re-circulation of condensate and multiple heat exchangers within.
Claims12
A steam generator wherein super heated steam is produced by heat transfer between a fluid heating medium and the vaporization liquid comprising in combination;
- a pair of spaced interconnected vaporization chambers, a transfer chamber therebetween, tube bundles positioned within each and extending from said vaporization chambers, said fluid heating medium within said vaporization chamber, means for heating said fluid heating medium including a solar lens configuration and heating tubes, means for supplying said vaporizationable liquid to said vaporization tube bundles for flash of vaporization therein, exhaust re-circulation means for said heating tubes including a power vent stack assembly, an exhaust scrubber in communication with said power vent stack, means for capturing and re-circulating condensate produced from said steam generator, expansion fittings in said vaporization tube bundles within said fluid heating medium, means for atomizing said vaporizationable liquid being injected into said tube bundles, and means for heating said vaporizationable liquid.
