ABSTRACT:
The objective of this project was to develop a conceptual design of an advanced water/steam solar central receiver, which would be more cost effective than the present design employed in the Barstow lOMWe pilot plant. Studies(l) have shown that the major cost in a solar thermal central

receiver plant is the collector sub-system (heliostats). The number of heliostats required for a given electrical power output is a function of, among other things, the efficiency of the conversion of heat energy to electrical energy (cycle efficiency). This fact justifies the search for improvements in the receiver/storage/electrical generation systems of the plant, with the potential for an overall cost benefit via a reduction of collector sub-system size. This project is directed to an advanced receiver sub-system primarily, and is limited to water/steam substance as the heat absorbing medium. An experimental program was included in the project to determine the feasibility of using rifled tubing in the high heat flux environment of the proposed solar receiver evaporator section. Rifled tubing has been shown to enhance the boiling heat transfer mechanism at lower heat flux levels in conventional boilers.
