Title:
SUPERCRITICAL CARBON DIOXIDE GENERATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/069457
Kind Code:
A1
Abstract:
The present invention relates to a supercritical carbon dioxide generating system that employs a plurality of heat sources. The system comprises: a pump for circulating working fluid; a plurality of heat exchangers for heating the working fluid through external heat sources; a plurality of turbines that are driven by the working fluid that has passed through and been heated by the heat exchangers; and a plurality of recuperators that implement heat exchange between the working fluid that has passed through the turbines and the working fluid that has passed through the pump, so as to cool the working fluid that has passed through the turbines and heat the working fluid that has passed through the pump. The heat exchangers may comprise: a plurality of restrictive heat exchangers having restrictive discharge conditions at the discharge ends thereof; and a plurality of heat exchangers without the restrictive discharge conditions. According to the present invention, by effectively positioning each heat exchanger according to conditions such as the inlet temperatures, the capacities, and the number of heat sources, the effects are realized in that one recuperator per heat source can be used in order to simplify the system configuration and enable the effective operation thereof.
