Thermodynamic evaluation of gas turbines for cogeneration applications
In this paper, the first and second laws of thermodynamics have been utilised to evaluate the performance of intercooled reheat regenerative gas turbine cogeneration plant. The effects of overall pressure ratio, cycle temperature ratio, pressure losses, and process steam pressure on energetic and exergetic efficiencies have been investigated. The results indicate that most of the exergy ...
