IMPROVED SPECIFIC FUEL CONSUMPTION OF OPEN-CYCLE GAS TURBINES BY UTILISATION OF WASTE HEAT

Because of the recent sharp rise in fuel costs, the U.S. Navy is reemphasising methods to reduce the specific fuel consumption of gasturbine powered ships to be introduced in future designs. This paper presents the results of a study in which the specific fuel consumption of open-cycle gas turbines was reduced by two alternate methods of utilising the waste heat by (a) generation of steam for combined gas and steam turbine power (COGAS) from an existing-engine design and by (b) incorporation of a recuperator for a new engine design.
