Abstract
A trough-type parabolic concentrator (1) for a solar thermal power plant comprises a reflector plate (3) bent in trough shape and a support structure (4) for supporting the reflector plate (3) and comprising a plurality of wooden segments (2) arranged in a row in the longitudinal direction of the trough. Each segment (2) is assembled from a plurality of wooden frames (5). Using wooden frames (5) as the basic element of the supporting structure (4) allows for a lightweight, simple and low-cost structure of the trough-type parabolic concentrator (1).
