Abstract We report a comparison between an efficiency-optimised parabaloidal concentrator and an efficiency-optimised tandem concentrator consisting of a primary paraboloid and focus-mounted secondary hyperboloid. The performance improvement (or otherwise) of a tandem collector (concentrator plus cavity receiver) is expressed as a relaxed paraboloid slope error and translated into a manufacturing cost advantage. At 900°C a cost advantage of a few percent is predicted. We conclude that a tandem collector based on a Brayton-cycle engine operating at 1200°C could be economically attractive.
