Central Receiver Solar Thermal Power System, Phase 1: preliminary design report. Volume II. System description and system analysis. [150 MW commercial tower focus plant and 10 MW pilot plant]
System descriptions of the planned 150 MWe commercial plant and the 10 MWe pilot plant are given. The commercial plant consists of 15 integrated collector--receiver modules featuring cavity receiver steam generators, focused heliostats, north field collector geometry, moderate slant ranges, and a short tower. Each module contains 1554 heliostats with a total mirror area of 63,666 m/sup 2/ and an internally mounted receiver on a steel tower with an aperture height of 90 m. The pilot plant configuration includes one full collector-receiver module of the commercial plant. The two stage thermal storage uses sensible heat for storage. The storage materials, hydrocarbon oil for steam generation and molten salt for superheating, are both used commercially for heat transport fluids. The high temperature steam generated by the molten salt stage provides for a maximum efficiency power cycle. Power generation utilizing a dual admission turbine maximizes performance and operating flexibility. This turbine permits operation from the receiver and/or thermal storage and supports the various modes of operation and cyclic requirements of a solar plant. The pilot plant makes maximum use of full scale components and subsystems of the commercial plant. Performance data are given and environmental impacts are discussed. (WHK)
