What does the gas turbine generator set fueling system indicate about fuel flow?

• A. Fuel bypasses the pump during low-load operation
• B. Fuel enters the pump and passes through the boost element
• C. Fuel is fed directly to the turbine without pressure boost
• D. Fuel is cooled before entering the pump

Answer: (B)

Fuel systems in a gas turbine are designed to deliver fuel at the right pressure to the combustor. The fact that fuel enters the pump and passes through a boost element shows there is a pressure-raising stage after the pump to ensure the fuel reaches the necessary high pressure for proper atomization and metering across all operating conditions. This boost step is what enables stable, controllable fuel flow as load changes. If fuel were to bypass the pump, or be fed directly to the turbine without any pressure boost, or be cooled before pumping, the system would not provide the required pressure for reliable combustion.
