Abstract
A simple vapor-power plant, completely self-contained in an enclosed space, whose working fluid executes, in a truly continuous fashion, a complete cyclic operation involving at least vaporization, expansion, condensation and recycling of itself by flowing steadily through a closed loop of continuous space consisting of several distinct funcational zones within a capillary (or porous) structure and an adjacent opened space, while converting the work of expansion into the corresponding mechanical work by a free-rotating turbine situated inside said opened space; said turbine being the only required basic moving-part of said vapor-power plant.
Claims3
A vapor-power plant comprising:
- a body;
- wall means defining an enclosed space within said body, and across which heat and work flow;
- a porous structure adjoining the inside surface of at least a portion of said wall means and containing continuous capillary passages, said continuous capillary passages being open at least in part to said enclosed space in at least two separated areas;
- a vaporizable working fluid wetting and saturating said porous structure;
- means for introducing heat to heat and vaporize said working fluid in the part of said porous structure near one of said separated areas;
- means for expanding the vapor formed from said working fluid;
- means for converting the work of expansion done by said vapor into mechanical work;
- means for removing said mechanical work;
- means for removing heat to cool and condense said working fluid vapor in the part of said porous structure near another of said separated areas;
- internal heat exchange means located inside said enclosed space, for exchanging heat with said working fluid;
- said porous structure being constructed so that when said liquid working fluid is vaporized in part of said porous structure, the capillary suction pressures created at the smaller menisci of said liquid working fluid being vaporized cause said working fluid to flow to said part of said porous structure where said vaporization takes place from said part of said porous structure where said condensate is formed through the larger capillary passages connecting said separated areas of said porous structure;
- said means for expanding said vapor and said means for converting said work of expansion into said mechanical work being located in said enclosed space relative to the location of said porous structure so that said working fluid may undergo said processes of vaporizing, expanding, condensing and returning itself to execute a complete cycle involving said processes in a closed system defined within said body.
