Abstract:
To improve a heat storage system comprising a heat source, a heat storage device and a heat sink between which heat is transported by a heat transporting medium such that satisfactory storage and utilization of heat by a heat transporting medium near its critical temperature is possible, it is proposed that the heat storage device be designed as a Ruths storage device, with a bath of liquid required as heat transporting medium for the Ruths storage device being provided in a storage volume, that the storage volume contain in addition to the bath of liquid a latent heat storage material, that the storage temperature be selected so as to lie in the range of the critical temperature of the heat transporting medium and below it, and that the heat storage system be operable in such a way that during the discharging of the heat storage device via the heat sink, the bath of liquid heat transporting medium constantly surrounds the latent heat storage material essentially with thermal contact.
Abstract:
A boiler type of steam engine is described which uses a conventional boiler with an external combustion chamber which heats water in a pressure chamber to produce steam. A mixing chamber is used to mix the steam from the boiler with recovered recompressed steam. Steam from the mixing chamber actuates a piston in a cylinder, thereafter the steam going to a reservoir in a heat exchanger where recovered steam is held and heated by exhaust gases from the combustion chamber. Recovered steam is then recompressed while being held saturated by a spray of water. Recovered steam from a steam accumulator is then used again in the mixing chamber. Thus, the steam is prevented from condensing and is recovered to be used again. The heat of the recovered steam is saved by this process.
Abstract:
A stand-alone long-distance closed-loop heat energy capture, conveyance, and delivery system, comprises three closed-loop modules in serial communication. The first module is in communication with a first closed-loop piping infrastructure interconnected with a source of heat energy, and has a LBP liquid circulating therein whereby the LBP liquid is converted into its gas phase when flowing through the source of heat energy thereby capturing a portion of heat energy therefrom, and is converted into its liquid phase when flowing through a first heat exchanger that transfers the captured-heat energy to a second closed-loop piping infrastructure wherein also is circulating a LBP liquid. The second closed-loop module may extend for long distances. The captured-heat energy in the second module is transferred to a third closed-loop piping infrastructure wherein is also circulating a LBP liquid. The captured-heat energy is transferred from the third module to a delivery site.

Abstract:
A system and method are provided for storing electric energy in the form of thermal energy. A thermoelectric energy storage system includes a working fluid circuit for circulating a working fluid through a heat exchanger, and a thermal storage medium circuit for circulating a thermal storage medium. The thermal storage medium circuit includes at least one hot storage tank, an intermediate temperature storage tank, and a cold storage tank connected together via the heat exchanger. A proportion of the storage medium is redirected to or from the intermediate storage tank from or to the hot or cold storage tank, joining another proportion which flows directly between the cold and hot storage tank.
Abstract:
A solar plant including a solar field for production of steam, a turbine using steam, and an excess steam storage and draw off system. The system includes a latent heat thermal storage module and a liquid displacement thermal storage module including a liquid volume and a steam blanket. The modules are connected together so that the steam produced passes through the steam blanket before passing through the latent heat module, condensing, to be injected in the liquid volume, the lower part of the liquid volume being connected to the solar field and to an outlet of the turbine to let in or return cold liquid. The liquid volume acts as a liquid displacement reservoir.
