Abstract

The efficiency of a Parabolic Trough (PT) Solar Power Plant heavily relies on its thermal performance. Modern technology has allowed for the creation of more efficient methods of producing steam and of collecting solar energy for thermal power generation. Ministry of New & Renewable Energy (MNRE) built and tested an 11.1 m2 parabolic trough concentrator (PTC). A system that generates steam indirectly by using concentrating solar power (CSP) is examined. The study examined absorbers' thermal properties, thermal efficiency of combined thermal exchangers, concentration ratio, heat efficiency, and steam generation to determine their influence on energy efficiency. The experimental findings display that 557.85 watts of energy are absorbed by the PTC receiver. The PT solar plant system has a thermal energy efficiency of 25 to 29 % and a concentration factor of about 200 on average. The parabolic trough concentrator generates a maximum of 9.1 kg.h-1 of steam.
