SOLAR RECEIVER HAVING BACK POSITIONED HEADER

摘要

Solar receiver (10) comprising at least two receiver panels (12) having a common outer front surface for receiving incident solar radiation from a field of mirrors (50). Said receiver panels comprise an array of side by side arranged heat exchange tubes (11), which have a substantially straight main portion (11.1) which extend in an upwards longitudinal direction and an inwards extending portion (11.2/11.3) for a connection to an input or output header (17. l/l7.2) for respectively distributing or collecting fluid to or from the heat exchange tubes (11), said receiver panels (12) are spaced apart in the upwards direction a a distance of Z cm The solar receiver is improved in that the header is spaced behind the front surface at a distance of A cm, wherein the quotient of Z and A Z/A, at the most equals the quotient of a vertical V and a horizontal H distance, V/H, from the header to a most far positioned mirror.
