Potential for using parabolic trough collectors to supplement power-cycle boilers
Technical Report

OSTI ID:6267625
An analysis has been made to the potential for using a parabolic trough solar collector system for preheat and boiling in a power generation cycle. The advantage of such a system is that solar energy is used to heat the water in a steam-Rankine cycle device up to the superheat regime, thus displacing the fossil fuel usually required. The temperature associated with this portion of the power cycle is typically on the order of 320/sup 0/C (600/sup 0/F) or less, which makes it compatible with current parabolic trough collector systems. A system model which lends itself to optimization studies has been constructed and exercised over a range of the multiparameter space involved. The collector field, storage, supplementary fossil boiler and superheater, and turbine/generator have been traded off to obtain a series of economically optimal systems for various years and solar fractions.
