Abstract
A cooling air cooling system operable to reduce fuel gum deposits within the cooling system when a gas turbine engine operates above a predefined percentage of rated engine power. The cooling system includes a recirculating loop including a plurality of heat exchanges in fluid communication with the recirculating loop. A first head exchange uses heat transfer fluid to cool cooling air used by the gas turbine engine. A second head exchange is a fluid-fuel head exchanger that uses combustor main fuel flow to cool the head transfer fluid circulating in the recirculating loop.
