Title:
SOLAR TOWER AND TROUGH COMBINED POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/174862
Kind Code:
A1
Abstract:
A solar tower and trough combined power generation system, comprising a trough-type heat collector (11), a tower-type heat collector (12), a preheater (21), a superheater (22), and a reheater (23). A heating pipe outlet of the trough-type heat collector (11) is connected to a heat transfer fluid inlet of the preheater (21); a heat transfer fluid outlet of the preheater (21) is connected to a heating pipe inlet of the trough-type heat collector (11); a heating pipe outlet of the tower-type heat collector (12) is separately connected to a heat transfer fluid inlet of the superheater (22) and a heat transfer fluid inlet of the reheater (23); a heat transfer fluid outlet of the superheater (22) and a heat transfer fluid outlet of the reheater (23) are connected to a heating pipe inlet of the tower-type heat collector (12). By using both the trough-type heat collector (11) and the tower-type heat collector (12) which work in respective optimum working temperature intervals, the system efficiency and the site utilization ratio of a tower-type mirror field are improved. Segmented heating of a working medium is implemented, and the flows of the heat transfer fluids in heat exchangers can be independently adjusted as needed, so that the heat exchange temperature difference and exergy loss are reduced and the power generation efficiency is improved.
