What is the purpose of the GE LM2500 gas turbine enclosure heater?

Correct Answer: Option B — To ensure fuel viscosity is maintained while the GTE is secured

The enclosure heater maintains the fuel system temperature within specified limits while the engine is secured. This prevents fuel waxing or viscosity increases, ensuring that the fuel remains pumpable and the system is ready for an immediate, reliable start without risking fuel system component damage or ignition delays.
