【 摘 要 】

• Future gas turbines operating with HHC fuels will have higher turbine inlettemperatures relative to natural gas operation.• Increased temperatures require better materials and more efficient coolingschemes. Increased cooling is unacceptable, so coolant must be used smarterand more sparingly.• Requires better prediction of combustor exit temperature distribution (patternfactor) and migration of high temperature core (hot streak) through highpressure turbine.
