Classification: CPC F | IPC F

Claim 8:
9. A method for controlling a rate of fuel coke formation in a fuel system of a turbine engine, comprising:
measuring an operating parameter of the fuel system at a first time, the operating parameter being associated with fuel coking in the fuel system;
determining a first amount of fuel coke formation for the fuel system using a signal representative of the operating parameter;
determining a current value for a rate of fuel coke formation in the fuel system by comparing the first amount of fuel coke formation to a second amount of coke formation for the fuel system, the second amount of coke formation being determined at a second time prior to the first time;
identifying a next scheduled maintenance event and a target amount of coke formation; and
adjusting the rate of fuel coke formation in the fuel system to a new value when the current value for the rate of fuel coke formation projects increases to the first amount of fuel coke formation that will exceed the target amount of coke formation before the next scheduled maintenance event, wherein the new value for the rate of coke formation projects increases to the first amount of fuel coke formation that do not exceed the target amount of coke formation before the next scheduled maintenance event.
