ABSTRACT:
As part of their Solar Central Receiver Program, the Department of Energy (DOE) contracted with Black & Veatch (B&V) to develop and evaluate a site-specific conceptual design of a solar central receiver system integrated with an existing cogeneration facility. The cogeneration facility
Early in the project, tradeoff studies were performed to establish key system characteristics. As a result of these studies, the use of energy storage was eliminated, the size of the solar facility was established at 37.13 MWt, and other site-specific features were selected.
The conceptual design addressed critical components and system inter- faces. The result is a hybrid solar/fossil central receiver facility which utilizes a collector system of DOE second generation heliostats with a receiver system consisting of an external, water/steam, screen tube receiver located atop a steel support tower. Other solar systems include the receiver piping system, the solar master control system, and the solar auxiliary electric system.
The value of the solar facility to CTU-WP was assessed based on performance, estimated cost, and revenue requirements over its operating life. The solar facility is expected to deliver 15 MWe net electrical output and 3.7 MWt process steam at the design point and 66 GWht during its first year of operation; this translates to an annual fossil fuel displacement of 48,100 barrels of oil equivalent. The cost of the solar facility in July 1, 1980 dollars includes $33.2 million for construction and owner's cost and $136,000 annually for operating and maintenance cost. In the economic analysis, the value of the solar facility to CTU-WP was computed to be 30 per cent. This value increases to 38 per cent for a 50 per cent increase in assumed fossil fuel prices and to 31.7 per cent for an operating life of 14 rather than 15 years.
A development plan was prepared which addresses the durations and sequencing of major activities which will lead from this conceptual design study to an operational facility. These major activities include licensing, test program, detailed design, procurement, construction, checkout and startup, and performance validation. The plan is based on the solar facility beginning operation in 1986.
Finally, B&V and CTU-WP conducted a test program at the CRS site. In this test program, valuable data were collected on direct normal insolation and heliostat mirror contamination.

studied is the Central Telephone & Utilities--Western Power (CTU-WP) Cimarron River Station (CRS) located near Liberal, Kansas. The CRS generates electricity for the CTU-WP system and delivers a portion of that electricity and process steam to the National Helium Corporation natural gas processing plant, located adjacent to CRS.Early in the project, tradeoff studies were performed to establish key system characteristics.
