Which statement best describes the role of the fuel nozzle in the combustor?

• A. Delivers fuel in a spray pattern that provides the best air-fuel mixture for combustion
• B. Filters fuel before delivery
• C. Ignites the fuel-air mixture
• D. Regulates fuel temperature

Answer: (A)

The fuel nozzle’s job is to atomize and deliver fuel as a fine spray into the combustor so it can mix with the incoming air to form a uniform air-fuel mixture for combustion. Fine droplets evaporate quickly and spread evenly, which helps ignite and burn the fuel consistently across the chamber, improving efficiency and reducing emissions. Filtering the fuel, initiating ignition, and regulating fuel temperature are handled by other parts of the system, not the nozzle itself.
