Exergy analysis of a gas turbine trigeneration system using the Brayton refrigeration cycle for inlet air cooling

摘要: AbstractTrigeneration with gas turbines as prime mover can improve energy utilization efficiency significantly because of their potential high economic and saving characteristic. In this article, a novel method for compressor inlet air cooling in turbine trigeneration is achieved by the Brayton refrigeration cycle driven used working fluid. Introducing provides advantage quite low temperatures close to 0 °C even lower, enhances performance significantly. The was evaluated both exergy efficiencies, latter providing good guidance system improvement. influences key parameters, which include extraction pressure ratio, mass rate, temperature (TIT), process heat pressure, ambient relative humidity on have been investigated. It found that air-cooled c...
