CYLINDRICAL PARABOLIC SUN ENERGY CONCENTRATOR WITH ABSORBER AND SUN TRACKING SYSTEM Russian patent published in 2007 - IPC F24J2/14 F24J2/18 

FIELD: solar power engineering, possible use in broad range depending on working area of concentrator, namely: ranging from production of hot water for home needs to production of high potential energy of overheated steam.

SUBSTANCE: solar energy concentrator is made in such a way that absorber located in its focus does not create a shadow in working mirror zone and allows positioning of concentrator rotation axis in gravity center of whole system. Absorber is represented by parabolic cylindrical concentrator with low focus distance, and focuses of concentrator and absorber do not coincide, between them, receiver with heat carrier is positioned, and system for tracking sun by azimuth and its elevation, based on calculated and constant characteristics, corresponding to geographical location where concentrator is mounted and provide required speed of rotation around polar axis and change of height during the day with consideration of time of the year. Device is a reverse mechanical drive, rotating a screw pair, to nut of which a toothed bar is rigidly fastened, during movement of which toothed sector turns and, simultaneously, turning the bar with the follower, which monitors daily sun height change.

EFFECT: production of maximal quantity of light stream energy, increased precision and reliability of device.
