GAS TURBINE THERMAL CYCLE ANALYSES CONSIDERING ECONOMIC AND ENVIRONMENTAL IMPACTS

A new methodology is presented to introduce economic and environmental impacts into the gas turbine thermal cycle analyses. It is founded through the preliminary quantitative analyses that: higher thermal efficiency and pressure ratio may not necessarily be the sensible choice when COE (Cost of Electricity) is considered to be the optimization target, andeven an optimum temperature ratio exists, especially for the peak load plant; environmental penalties can serve as an incentive factor to improve the optimum values, and its influencevaries according to the pollutant charge levels.
