The Honeywell/Black and Veatch proposed POCE Baseline Design features a tower-centered field of low-profile, focusing heliostats which concentrate redirected solar energy into a cavity receiver. The receiver aperture is an annulus which subtends a full 360 degree heliostat field. Water/steam is the heat transfer fluid which transports heat energy to either the prime mover or to a phase change thermal storage subsystem. The steam turbine is based on an 850 psi/950/sup 0/F steam cycle, and the thermal storage unit is a phase change salt tank unit which delivers steam to the turbine at 450 psi/510/sup 0/F. A detailed study of once-through versus drum-type boilers was conducted and the once-through concept was rejected because of control problems under varying solar flux conditions. The proposed design features a drum boiler and a dry heat rejection system. A summary listing of the POCE specifications is given. Subsystems and trade-off studies, the systems effectiveness program plan, special facilities, and information flow for subsystems are described. (WHK)
