Résumé

The exhaust gases of a gas turbine carry a significant amount of thermal energy that is usually expelled to the atmosphere. The paper explores the utilisation of the exhaust gases of an open-cycle-twin-shaft gas turbine. The temperature of the exhaust gases and the heat that can be put to benefit for precooling the air are determined. The specific network and efficiency of a precooled cycle have been calculated and compared to conventional systems. It has been concluded that the precooling has a marked effect on efficiency.
