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...

In the Modern scenario, the naturally available resources for power generation are being depleted at an alarming rate; firstly due to wastage of power at consumer end, secondly due to inefficiency of various power system components. A Combined Cycle Gas Turbine (CCGT) integrates two cycles- Brayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall pl...

A new generation of small scale (less than 20 MWe) biomass fueled, power plants are being developed based on a gas turbine (Brayton cycle) prime mover. These power plants are expected to increase the efficiency and lower the cost of generating power from fuels such as wood. The new power plants are also expected to economically utilize annual plant growth materials (such as rice hulls, cotton g...

We read with great interest the paper by Brayton et al. (1). This paper is nearly identical to our recent publication in JACC: Cardiovascular Interventions (2). It is interesting that 2 similar papers using the same data would be published in the JACC family of journals just a few months apart. Although Brayton and colleagues briefly acknowledge our paper in their discussion section, there are ...
