Apparatus is described for use with a solar concentrator such as a parabolic dish (12, FIG. 2) which concentrates sunlight onto the small opening (18) of a solar receiver (16), for protecting the receiver in the event of a system failure that could cause concentrated sunlight to damage the receiver.

Apparatus is described for use with a solar concentrator such as a parabolic dish (12, FIG. 2) which concentrates sunlight onto the small opening (18) of a solar receiver (16), for protecting the receiver in the event of a system failure that could cause concentrated sunlight to damage the receiver. The protective apparatus includes a structure which can be moved from a stowed position (30) where it does not block sunlight, to a deployed position (30A) wherein it forms a tube which substantially completely surrounds an axis (26) connecting the receiver opening to the center of the concentrator at locations between the receiver and the concentrator.

A solar heating apparatus comprising: a reflector dish concentrator having an axis; a solar receiver positioned along said axis to receive concentrated sunlight from said reflection dish through a receiver opening; a protection structure having a central opening and a generally tubular body configuration with a side wall surrounding said receiver opening; said protection structure being extendible from said receiver in the direction of said reflector dish such that the tubular body of the protection device extends into the reflected sunlight from the concentrator with a portion of the sunlight impinging on the side wall surface while sunlight is permitted to pass through the central opening from the concentrator to said central opening.
