OPTIMIZATION OF AN OPEN CYCLE GAS TURBINE POWER PLANT USING EXERGOECONOMICS
The purpose of current study is to analyze the performance of an open cycle gas turbine power plant using the concepts of exergoeconomics. Exergoeconomic technique involves the use of Second law of thermodynamics and assigns monetary values to the thermodynamic quantity known as exergy. Analyses based on exergoeconomic criteria are done for the open cycle gas turbine power plant turbine. The methodology is illustrated using the example of a 25 MW open cycle gas turbine power plant. Optimization has been done for the open cycle gas turbine power plant as tradeoffs between the unit product cost of the compressor and combustion chamber as functions of compressor pressure ratio and unit product costs of combustion chamber and gas turbine as functions of turbine inlet temperature.
