Central Receiver Solar Thermal Power System, Phase 1: preliminary design report. Volume IV. Receiver subsystem. [150 MW commercial tower focus plant and 10 MW pilot plant]
The design, performance, operational characteristics, testing, and environmental impact of the commercial/pilot plant receivers are presented. The commercial-plant receiver subsystem consists of 15 identical tower-mounted steam-generating receivers. Each receiver is designed to accept energy from a concentrating solar-collector field consisting of 1554 heliostats, each with 41 m/sup 2/ (441 ft/sup 2/) of reflective surface area. The steam output of each receiver module feeds a common manifold system from which either the Electrical Power Generation Subsystem (EPGS) or the Thermal Storage Subsystem (TSS) can be served. The plant can operate quite efficiently with one or more receivers inoperative. Each receiver is a natural-circulation steam generator designed to generate superheated steam at a pressure of 10,687 kPa (1550 psig), a temperature of 789 K (960/sup 0/F), and a flow rate up to 75,300 kg/h (160,000 lb/h). Each steam generator is arranged in a cavity configuration into which concentrated solar energy is directed. In normal operation, entering feedwater flow is controlled by a conventional three-element regulator. Radiant solar energy heats water in the boiler section and vaporizes a portion of it, creating a density-gradient imposed circulation of the water/steam mixture upward to the drum and water downward from the drum to replenish the boiler section. The drum separates saturated steam from the water, routing the steam to the superheater section, where it is heated to the specified output temperature. The steam is then piped down the tower to the EPGS/TSS supply manifold. (WHK)
