In this paper combined Brayton–Rankine cycle was mathematically simulated. In the Matlab program package an adequate numerical procedure has been developed to determine the maximum thermal efficiency of the combined cycle limited by the temperature of exhaust gases at the entrance of the gas turbine and the temperature of the condensation of water vapour in the steam condenser. Furthermore, add...

Power generation using gas turbine power plants operating on the Brayton cycle suffers from low efficiencies. In this work, a solid oxide fuel cell (SOFC) is proposed for integration into a 10 MW gas turbine power plant, operating at 30% efficiency. The SOFC system utilizes four heat exchangers for heat recovery from both the turbine outlet and the fuel cell outlet to ensure a sufficiently high...

2014 This report is an account of the design, checkout and solar testing of a cavity receiver using metal gas-in-tube heat exchangers. The design represents a scale model of a Brayton cycle solar electric plant receiver. The program span from initiation of design to test completion was 32 months. The DOE-Central receiver test facility was utilized in this inaugural test. Tests involved controll...
