LIFE CYCLE ASSESSMENTSOF GAS TURBINE USING INLET AIR COOLING SYSTEM
Abstract
To achieve a life cycle assessments of energy systems with both power output and economical profits maximized is considered as the main objective of operation management. This paperis designedto evaluate boththe performance of agas turbine added with an inlet air cooling system as well as its life cycle cost. Accordingly, a thermodynamic model and an economic model are developed respectively to derive an analytical formula for calculating the cooling loads and life cycle cost. The majorresults show that the output power for gas turbine power plant with the cooling system (120MWH) is higher than that of a gas turbine power plant without the cooling system (96.6 MWh) at peak condition; while the life cycle cost of former plants is lower thanthe latter ones.Thus, the proposed methods suggest potential cost-effective improvements feasible and achievable through changing the structure of the system.
