Abstract
An igniter lifing system and method is provided that facilitates improved igniter plug wear and remaining life prediction. The igniter lifing system and method uses operating conditions measured during ignition to estimate how much wear has occurred on an igniter. Specifically, the igniter lifing system and method uses ignition time and pressure data to predict wear on the igniter plug and make an estimate of the remaining life. In one embodiment, the igniter lifing system calculates the incremental igniter wear for each use of the igniter as a function of the turbine combustor pressure during that use. Then, by summing the incremental igniter wear calculations, the accumulated igniter wear can be calculated, and an estimate of the remaining igniter life can be determined.
