Gas Turbines in Cogeneration: Overall Analysis and Numerical Predictions

摘要

A method for performance analysis of gas turbines for cogeneration applications is presented. Energy and energy balances allow presentation of data in terms of conventional or second-law parameters, as well as examination of the trends with respect to cycle variables and cogeneration options. The results show that even though gas turbines (and particularly regenerative solutions) are very flexible for cogeneration purposes, care has to be exercised in matching thermal energy production conditions and cycle variables in order to achieve optimal performance.
