研究目的
To analyze the technical and economical feasibility of using parabolic trough collectors to preheat boiler feedwater for expanded cork agglomerate production.
研究成果
The integration of solar thermal energy for pre-heating boiler feedwater in ECA production is technically feasible and can provide significant energy savings. The system with the lowest LCOH was found to be without a buffer tank, with a solar field composed of 6 parallel loops and 6 collectors in series per loop, capable of satisfying around 36.9% of the energy needs for feedwater pre-heating.
研究不足
The study assumes constant operation and maintenance costs and does not account for potential variability in solar irradiance or plant operation schedules. The economic analysis is based on specific cost assumptions that may vary by location.
1：Experimental Design and Method Selection:
The study involved designing a solar thermal system for pre-heating boiler feedwater using parabolic trough collectors. A TRNSYS model was developed to simulate the system's performance.
2：Sample Selection and Data Sources:
Data from a real ECA production facility in Portugal was used, including feedwater consumption and thermal energy demand.
3：List of Experimental Equipment and Materials:
NEPSOLAR PolyTrough 1800 collectors, Therminol 66 as heat transfer fluid, and a buffer tank for thermal storage.
4：Experimental Procedures and Operational Workflow:
The system's operation was simulated under various configurations to assess performance, including different solar field sizes, buffer tank volumes, and heat exchanger sizes.
5：Data Analysis Methods:
The performance was evaluated based on the useful energy delivered to the boiler's feedwater and the levelized cost of heat (LCOH).
