Solar thermal electric power systems collect and concentrate solar energy to heat a working fluid which is used to drive conventional Rankine or Brayton cycle turbine-generator equipment. A principal advantage of the central receiver system is the very high temperatures that can be produced in the working fluid. However, commercially available high temperature matal tube materials are not suitable for extended operation above about 1600 F at the stress level expected in the high temperature heat exchanger. An investigation was, therefore, conducted with the objective to study suitable ceramic materials. It was found that silicon carbide U-tubes are suitable for use in a solar central receiver cavity type heat exchanger.
