Solar heated-air cavity receiver development (SHARE)
Studies of advanced receivers for solar thermal heated-air Brayton power systems have been under way at MIT/Lincoln Laboratory since 1975 and have shown that the ceramic domed cavity receiver concept is a promising approach for central receiver systems. Development of the novel ceramic receiver concept, which heats pressurized gas to 1800/sup 0/F (1000/sup 0/C) for use with gas turbine units, has been proceeding under Department of Energy sponsorship since May 1978. The advanced development program is focused on the solution of technologically pacing items in the receiver; for instance, the development of a high-temperature seal between the pressurized air and high-temperature ceramic dome material. Progress made on a number of elements in the development program including ceramic dome stress calculations, metalization of ceramics, selection of a preferred receiver/dome sealing approach, and mechanical seal leak measurement is discussed. The continuing experimental program to develop and demonstrate seals on ceramic domes to one-foot diameter is described.
