Solar production of intermediate-temperature process heat, phase I design. Preliminary design report
Technical Report
·
OSTI ID:6486448
The preliminary design of the system including the results of the analyses that were performed to arrive at the preliminary design are outlined. The system consists of 44,100 ft/sup 2/ of parabolic trough concentrating solar collectors to be oriented in a north-south configuration and to track East-West. A heat transfer fluid will be circulated in a closed loop fashion through the solar collectors and a series of heat exchangers. The inlet and outlet fluid temperatures for the collectors are 380/sup 0/F and 450/sup 0/F respectively. These temperatures will be constantly maintained via a variable flow rate through the collectors (the flow rate will vary in direct proportion to the level of insolation). Superheated steam will be the final product of the solar energy system. The plants' boiler feedwater at 245/sup 0/F will be preheated to saturated liquid conditions at 180 Psig and 375/sup 0/F in the first heat exchanger. It will then enter an unfired boiler where it will undergo a phase change to a saturated vapor. A third heat exchanger tube bundle located in the vapor region of the boiler will provide 25/sup 0/F superheat for the steam. Final steam quality will be 400/sup 0/F and 175 Psia.
