Solar electrical generating system

Номер: GB0002344645A
Принадлежит:

A solar electrical generating system comprises a hot liquid storage tank containing a liquid of low boiling point. Heat from the sun is used to produce gas in the tank, the gas being piped off to drive a turbine/electrical generator assembly. The turbine is connected to a cylindrical permanent magnet which can rotate freely. A copper coil inside the cylindrical magnet produces electricity which can be tapped off and passed to a capacitor. The gas from the turbine is directed to a cold liquid storage tank, from which liquid is pumped back to the hot liquid storage tank. A solar powered car may have two sets of solar electrical generating systems, one located at the front of the car and one at the back.

SELF-SUSTAINING ON-SITE PRODUCTION OF ELECTRICITY AND/OR STEAM FOR USE IN THE IN SITU PROCESSING OF OIL SHALE AND/OR OIL SANDS

Номер: CA0002559117A1
Принадлежит:

Oil shale and/or oil sands are utilized to generate electricity and/or steam at the site of the oil shale/sands deposit in an in situ process for recovering oil from the deposit. Bulk shale/sands material is removed from the deposit and combusted to generate thermal energy. The thermal energy is utilized to heat water to generate steam. The steam can be used directly in the in situ process or utilized to drive a steam turbine power generator located in close proximity to the deposit to generate electricity. The electricity generated on-site may be utilized to drive an in situ conversion process that recovers oil from the oil shale/sands deposit. Also, the exit steam generated by the on-site turbine generator can be used on-site to drive the in-situ conversion process.

A reflector element, parabolically deformable under pressure, has a first elastic diaphragm (1), which has a reflective layer and a second transparent diaphragm (9). The two diaphragms are clamped along their periphery in a bearing ring (3) and form a pressure tight chamber (10). The bearing ring is arranged like a wheel by means of two cable arrangements (7, 8) on a central collector axis (4). This is pivotably mounted at its foot in a joint (5), so that the bearing ring (3) can be rolled on a support base (11), which permits azimuth adjustment of the collector. For adjustment of the angle of elevation, the joint (5) is height adjustable. The collector axis (4) at its other end carries a heat absorption unit (2), which is arranged in the area of the focal point of the reflector. In order to reduce reflection losses, the transparent diaphragm (9) runs essentially perpendicular to the direction of the incident light, which is achieved by supporting it against the front cable arrangement ...

A solar power plant for generating steam is comprised of a spherical shell, the interior of which is sealed from the outside atmosphere and which is mounted adjacent the top of a vertical tower. A plurality of heliostats surrounds the tower and the direct sunrays onto the sphere for heating the same sphere. A spray nozzle within the sphere directs water supplied to it from an external source onto the interior surface of the sphere to create steam. The steam is withdrawn and directed to a turbine or the like for generating electricity. A motor rotates the sphere about its vertical axis thereby regularly exposing a different portion of the sphere to the heliostats to prevent the sphere from melting.

Method for the natural-draught cooling of a high-concentration thermoelectric solar plant that includes a central receiver or tower with a heliostat field, wherein the tower is used as a natural-draught cooling tower. The steam originating from the turbine will be made to circulate through a series of condensers located at the base of the tower, where said condensers condense the steam therein and discharge the condensation heat to the atmosphere. The fluid responsible for this heat exchange is the air at ambient temperature at the base of the tower. Once condensed, the steam is pumped back towards the receiver so that it can be re-used as a heat-transfer fluid. The cooling air travels up through the tower and exits through the highest part thereof. The plant can be used to reduce not only its own electricity consumption, but also water consumption.

The liquid pump within the solar turbocharger is used to boost the refrigerant pressures into the solar collector, the refrigerant absorbs heat inside the solar collector and changes phase from a liquid to a vapor. The vapor is expanded across the turbine causing the turbine to spin.

Solar direct steam generation power plant combined with heat storage unit

Номер: US20140216032A1
Автор: Alexander Levin
Принадлежит: Individual

The invention proposes a concentrating solar power plant, which includes a heat storage unit allowing operation of the power plant for some hours on the base of accumulated heat. An important feature of the plant constitutes its ability to operate with direct steam generation (DSG) immediately in the concentrating solar collectors. Heat charging of the heat storage unit are performed with changing temperature of superheated steam, which circulates via the heat storage unit and a sub-field of the concentrating solar collectors; this sub-field serves solely for temperature elevation of the circulating superheated steam. Heat discharging of the heat storage unit is executed by heating the circulated superheated steam, which is delivering from a mixer-evaporator. This mixer-evaporator serves, in turn, for evaporation of condensate obtained in a condenser of a turbine unit; the evaporation process is based on utilization of sensible heat of the superheated steam.

The system also has an assembly for generating electricity during the nighttime, which assembly includes a storage structure disposed between the solar collector and the boiler. This storage structure includes a plurality of separate storage stacks, each housed underground and including a plurality of heat conductive pipes interdigitally arranged with a plurality of plates constructed from twice-baked clay and arranged resting on a base formed from a similar clay as the plates. Solar energy is absorbed by the collector and transferred to the storage structure by means of suitable piping for storage in the twice-baked clay plates. When the stored heat is to be later used, as in the nighttime or on overcast days, a switching device uncouples the collector from the storage structure and couples the storage structure to the boiler.

A solar thermal electric energy system utilizes a solar receptor having a double paned glass window with cooling liquid circulating therethrough. This serves as a window for a solar heat receptor cavity having a number of water or steam carrying tubes therein. A portion of the tubes operate at a temperature range suitable for heating boiler water and another portion of the tubes is at a higher temperature which serves as steam superheat. The liquid flowing through a pair of window panes is triethylene glycol and in addition to cooling the window has an index of refraction which matches the window to provide the most efficient conduction of solar energy to the heat recepting tubes behind the window. The power plant itself includes heat saving jackets around the steam headers to provide for boiler feed water preheat and has both high pressure and low pressure turbines to utilize most efficiently the water being heated by the solar receptors.
