Effects of High Availability Fuels on Combustor Properties

Engines now in production or under development were designed for satisfactory performance and life on current specification fuels many of these engines may not be able to handle the stress implied by a broadened fuel specification. Among the fuel properties of greatest concern to turbine engine combustion are the aromatic content, the distillation curve, and the viscosity. Fuel bound nitrogen is one new property which has emerged from the use of syncrude fuels because of additional NOx found in the exhaust.
