The paper deals with the thermodynamic analysis of complex intercooled recuperated gas turbine cycle. This work is basically energy and exergy analysis of various components of the cycle using the energy and exergy balance approach. Perfoming energy balance in the components helps to estimate the percentage energy loss and first law efficiency of the cycle, while exergy analysis of the cycle gives details about the irreversibi lities, percentage cxergy destroyed and second law efficiencies of components of the cycle. The paper analyses the cooled gas turbine with blade cooling by using air bled from the compressor and utilization of the turbine exhaust for recuperation purpose. The estimation of exergy destruction due.to inefficiencies of the cycle comronents have been found for gas turbtnc exhaust gas ( 16. 95%) followed by combustion-chamber (8.30%) and thereafter for gas turbine (7.70%). The sum of exergy destruction in the cycle is around 48%.
