Combustor technology for broadened-properties fuels
In order to increase the availability and reduce the cost of future fuels for aircraft gas turbine engines, it may be necessary to broaden fuel specifications. Anticipated changes in fuel properties, and the effects of these changes on combustion system performance, operating characteristics, durability, and emissions are briefly reviewed, and results to date of a program being conducted to develop and demonstrate combustor technology required to utilize broadened-properties fuels in current and next-generation engines are described. Combustion system design considerations and tradeoffs for burning broadened-properties fuels are discussed, and test experience with several applicable combustor design modifications to the G.E. CF6-80A combustion system is reviewed. Modifications have been demonstrated to improve liner cooling and reduce smoke in the conventional annular combustor, thereby reducing effects of variations in fuel hydrogen content. Advanced staged and variable geometry combustor concepts for burning broadened-properties fuels have also been demonstrated.
