20160040909 | ABSORBER ARRANGEMENT FOR A TROUGH COLLECTOR - The invention relates to an elongated absorber arrangement for a trough collector, which is subjected to concentrated radiation over its length during operation, and which has means for transporting heat-transporting fluid through the absorber arrangement. The absorber arrangement has at least one fluid-free absorber space for concentrated radiation, which has a thermal opening leading into its interior and walls for absorption of the heat incident into it. The means for transporting the fluid have a supply arrangement and a drain arrangement which are operatively connected to one another by means of a heat-exchanger arrangement through which fluid flows, wherein the same extends along the length of the absorber arrangement, is constructed for the throughflow of the fluid in transverse flow for the length of the absorber arrangement and is thermally connected to the at least one absorber space in such a manner that the fluid is heated during operation in transverse flow from an inlet temperature to the operating temperature and reaches the drain arrangement at this temperature. | 02-11-2016 |
20150354856 | TROUGH COLLECTOR WITH CONCENTRATOR ARRANGEMENT - The invention relates to a trough collector with a primary concentrator, which concentrates solar radiation into a focal line region, with an arrangement for secondary concentration of the solar rays reflected by the primary concentrator, which arrangement concentrates the solar rays further into focal point regions. The arrangement for secondary concentration has a plurality of rows of secondary concentrators which have identical orientation in a row, but have differing orientation from row to row. Further, means are provided in order to keep one of the rows in the operating position and the other rows in a rest position. Thus, a range of the skew angle can be assigned to each of the rows and in the event of the change thereof, another row is brought into operating position. | 12-10-2015 |
20150096289 | PRESSURISED ENERGY STORAGE SYSTEM IN WHICH THE HEAT ACCUMULATOR IS ARRANGED IN AN OVERPRESSURE ZONE - The invention relates to a compressed air energy storage system comprising a pressure accumulator ( | 04-09-2015 |
20140332054 | SOLAR COLLECTOR HAVING A PIVOTABLE CONCENTRATOR ARRANGEMENT - The invention relates to a trough collector comprising a number of secondary concentrators, by which the solar radiation concentrated by the concentrator of the trough collector in a first direction transverse to the length thereof is concentrated in a second direction running along the trough collector, wherein the secondary concentrators each have a first, front reflecting wall and a second, rear reflecting wall which concentrate the radiation in the second direction, and wherein the secondary concentrators are arranged such as to be synchronously pivotable with one another, preferably about a respective pivot axis fixed with respect to the primary concentrator, such that as the position of the sun changes, the secondary concentrators can always be oriented in accordance with the incident radiation. The invention is characterised in that the first and the second reflecting wall of the secondary concentrators have different lengths in the entry region of the radiation, such that a longer reflecting wall of one secondary concentrator lies in each case next to a shorter reflecting wall of the adjacent secondary concentrator. The secondary concentrators can thereby be arranged side by side without a gap, yet remain pivotable over a range of minus 20 degrees to plus 70 degrees with respect to the primary concentrator. | 11-13-2014 |
20140071439 | METHOD AND APPARATUS FOR MEASURING THE REFLECTION PROPERTIES OF A REFLECTOR - The invention comprises a method and a device for measuring a reflector for radiation during the operation thereof, in which to determine the current reflection properties of the reflector in a number of at least one measurement points provided in the path of the radiation reflected by the reflector, the pattern of predetermined characteristics of the currently reflected radiation is measured and compared with a predetermined reference pattern, wherein the current geometrical properties of the reflector are inferred from the comparison and in the event of undesired geometrical properties, appropriate operational parameters of the reflector are modified. This method is preferably applied in trough collectors for solar power plants, in order to measure flexible concentrators arranged in a pressure cell, during their operation. | 03-13-2014 |
20140026944 | ABSORBER TUBE FOR A TROUGH COLLECTOR - The invention relates to a trough collector having a focal area and an absorber tube arranged in the focal area, said absorber tube having an insulating area that extends from its outer surface to the inside, enclosing preferably a transport channel that runs through the absorber tube along its length and carries a heat-transporting medium, and is penetrated by at least one thermal opening that extends radially from the outside through the insulating area to the transport channel. According to the invention, the at least one thermal opening comprises a constriction for radiation passing through it, the focal area being located in the constriction. | 01-30-2014 |
20130247961 | SOLAR COLLECTOR HAVING A CONCENTRATOR ARRANGEMENT FORMED FROM SEVERAL SECTIONS - Due to the further concentrators of a second concentrator arrangement in a linear concentrator configured as a trough concentrator, the concentrated radiation is concentrated in focal point areas, with the consequence that higher concentration of the radiation and thus higher temperatures are achievable in the absorber pipe. In order to lower the exponentially increasing heat losses in the absorber pipe (due to the higher temperatures), an absorber arrangement is provided in synergy, comprising rows of individual thermal openings, wherein these rows lie adjacently to each other. | 09-26-2013 |
20130206356 | HEAT STORE - Known high-temperature heat storage devices for the storage of heat at a temperature above 100° C. having a container for heat-storing bulk material such as gravel/ceramic spheres have a steel wall which is constructively extremely complex to manufacture for larger heat storage devices or the storage of heat at higher temperatures. According to the invention, the side wall of the heat storage device for its part is supported by a supporting bulk material and is preferably inclined, with the result that the side wall is substantially less stressed and can be made of a non-metal material such as, for example, concrete. Such a heat storage device is simple and inexpensive to manufacture and allows long-term storage of larger amounts of heat at high temperatures. | 08-15-2013 |
20120266868 | PARABOLIC COLLECTOR - A parabolic collector for the concentration of solar radiation has a reflective surface which is approximated to an ideal paraboloid and has a number of individual collectors. According to the invention, individual collectors are provided with a pressure cell with a concentrator formed from a flexible film, whereby, under operating pressure conditions, the concentrator is curved differently in a predetermined manner in a first and in a second direction for approximating the ideal paraboloid, such that the radius of curvature in the first direction is greater than that in the second direction. The production method for such a concentrator consists in the fact that the outline of the individual collectors is designed in the outline of the parabolic collector, the true dimensions of the individual collectors being determined from the intersection of cylinders positioned on the outline with the paraboloid of the parabolic collector. | 10-25-2012 |
