Which of the following statements is true concerning the fuel oil ignition system of the marine gas turbine engine shown in the illustration? Illustration GT-0017

Correct Answer: Option B — The igniters will denergize when the gas generator exceeds a preset RPM.

Gas turbine ignition systems are designed for starting sequences only. Once the gas generator reaches a self-sustaining speed, typically a preset RPM, the igniters de-energize to prevent unnecessary electrode erosion and thermal stress. Continuous ignition is generally reserved for specific adverse weather conditions or low-power operations, not normal steady-state running.
