What atomizes the fuel in the combustion liners?

• A. Fuel nozzle
• B. Fuel injector
• C. Atomizer
• D. Spray ring

Answer: (A)

Atomizing the fuel means turning the liquid into a fine spray so it can mix quickly with the combustion air inside the liner. The fuel nozzle is the part that does this in the combustor: it delivers high-pressure fuel through small passages and often uses a swirling or shattered-flow design to break the liquid into droplets. This created spray, when exposed to the hot air, promotes rapid, complete combustion and stable flame in the liner. The fuel injector is a broader term for delivering fuel, but the actual atomization action—the spraying into small droplets—happens within the nozzle assembly. The atomizer is a general term for devices that do atomization, and while the nozzle contains the atomizing elements, identifying the nozzle as the responsible component best reflects what creates the spray. The spray ring mainly helps distribute the spray around the circumference and does not itself perform atomization.
