Title: Single bi-temperature thermal storage tank for application in solar thermal plant

Abstract

Thermocline storage tanks for solar power systems are disclosed. A thermocline region is provided between hot and cold storage regions of a fluid within the storage tank cavity. One example storage tank includes spaced apart baffles fixed relative to the tank and arranged within the thermocline region to substantially physically separate the cavity into hot and cold storage regions. In another example, a flexible baffle separated the hot and cold storage regions and deflects as the thermocline region shifts to accommodate changing hot and cold volumes. In yet another example, a controller is configured to move a baffle within the thermocline region in response to flow rates from hot and cold pumps, which are used to pump the fluid.

  • A liquid storage tank for storing a dual temperature liquid comprising an enclosed tank which is circular in horizontal section; a vertical radial stationary partition in the tank; a vertical radial partition in the tank rotatably movable about the vertical axis of the tank; a seal preventing liquid flow between opposite sides of the movable partition and opposite sides of the stationary partition; an opening for feeding a liquid to a first side of the stationary partition and withdrawing liquid therefrom; and an opening for feeding a liquid to a second side of the stationary partition and withdrawing liquid therefrom.
  • The invention relates to a device sensitive to a temperature gradient or to a heat flow comprising at least one elementary cell formed by a thin layer made from a first electric conductor or semiconductor, such as constantan, coated with a very thin electrolytic layer of a second electric conductor or semiconductor, such as copper. It has been discovered that induced electric currents flow through the surface separating the conductors, the electric voltages observed in each of the conducting or semiconducting layers being proportional to the instantaneous spatial mean of the surface thermal gradient. The invention also relates to themore » application of such cells for measuring temperature gradients and heat flows and for converting heat energy into electric energy.« less
  • Renewable energy technologies based on solar energy concentration are important alternatives to supply the rising energy demand in the world and to mitigate the negative environmental impact caused by the extensive use of fossil-fuels. In this work, a thermodynamic model based on energy and exergy analyses is developed to study the transient behavior of a Concentrated Solar Power (CSP) supercritical CO2 plant operating under different seasonal conditions. The system analyzed is composed of a central receiver, hot and cold thermal energy storage units, a heat exchanger, a recuperator, and three-stage compression and expansion subsystems with intercoolers between compressors and reheatersmore » between turbines, respectively. From the exergy analysis, the recuperator, the hot thermal energy storage, and the solar receiver were identified as the main sources for exergy destruction with more than 70% of the total lost work in the plant. These components offer an important potential to improve the system’s performance via design optimization. With reference parameters, the system reaches efficiencies of about 18.5%. These efficiencies are increased with a combination of improved design parameters, reaching values of between 24.1% and 26.2%, depending on the season, which are relatively good for CSP plants.« less
  • A support deck extends on a level above the bottom of a hold of a vessel carrying low temperature liquefied storage spherical tanks, from bulkheads of the hull so as to surround such spherical tanks, while a horizontal support ring projects from the outer surface of the spherical tank and is supported on the support deck through support chocks. The circular inner peripheral edge of the support deck is supported by brackets erected on the bottom plate of the hold and radially extending toward the bulkheads or by columns erected on the bottom plate of the hold. In one construction,more » the inner peripheral edge of the support deck has an annular girder attached to the under side thereof and such girder is supported by brackets or columns. Further, in another construction, arcuate girders are provided only in regions close to longitudinal or transverse bulkheads and supported by brackets, and adjacent girders are interconnected by an arcuate leg plate erected on the bottom plate of the hold.« less
  • The present invention relates to a method of forming a solar collector, or absorber, panels or a heat storage tank, suitable for heating water using solar energy. It also relates to articles of manufacture so formed and to solar water heating apparatus using said articles. Three methods of forming the panel or tank from two sheets of uncured elastic material, such as EPDM rubber, by simultaneously bonding and curing such material around the peripheral edges of the two sheets and at spaced apart, discrete areas over most of the interior areas of the sheets. In one form of the method,more » one of the sheets is coated with a layer of release agent, over all areas except the discrete areas and the peripheral areas so that only such uncoated areas will bond during cure. In another form, a sheet of non-adherent plastic slightly smaller than the two sheets and having holes or holidays to form the discrete areas is bonded between the two sheets. In a third form, the peripheral edges are first sealed to form a chamber, then the chamber is inflated and a forming die presses together the discrete areas only. Preferably, but not necessarily, reinforcing fibers may be employed or molded, into at least one of the uncured sheets. As articles of manufacture the absorber, or tank, each includes at least one inlet and one outlet at opposed edges of the so formed chamber. Further, the storage tank has a portion of the enclosed volume adapted to receive a heat exchanger. This is made possible by omission of the discrete bonded areas over about one-fourth of the area to the two sheets. In apparatus form, a solar absorption panel and a storage tank so formed (and interconnected inlet to outlet) are mounted back-to-back by an enclosing structure suitable for roof-top or ground-pad mounting and connection into a water system for solar heating of domestic water.« less
