Evaluation of the FMC line cavity central receiver concept

OSTI ID:6534048

The FMC concept utilizes a line cavity type central receiver system. Each array comprises several 60-m long 1-MWe modules. The north- and south-facing linear cavity receivers are illuminated by north and south heliostat fields, respectively. The heliostats have variable-focus mirrors and track the sun in elevation only. The receiver modules are mounted on steel truss towers at an aperture height of 60 m. The baseline heliostat field design utilizes additional wing corner areas at the ends of each array to reflect early morning and late evening sunlight into the receivers. The storage, steam turbine, and the remaining subsystems and equipment are assumed to be the same as those defined for the systems being studied by Martin Marietta Corporation or McDonnell Douglas Astronautics Company for ERDA's 10-MWe Pilot Plant. The evaluation presented reviews the various features of the FMC line cavity central receiver concept including the line focus heliostat and receiver subsystem performance and the planned heliostat experiment. Also examined are possible modifications of the FMC baseline configuration to improve the system performance and make preliminary economic comparisons with the current technology point focus designs.
