Which components work together to atomize the fuel oil in a pressure atomizing burner?

• A. Sprayer plate and tip
• B. Sprayer nozzle only
• C. Nozzle and chamber
• D. Pump and valve

Answer: (A)

In a pressure atomizing burner, breaking the fuel into tiny droplets happens when the fuel is forced through a small, high-pressure passage in the nozzle tip and then hits the sprayer plate. The tip creates a high-velocity jet, and the sprayer plate, with its many small openings, shears and disrupts that jet into fine droplets. This combination—the precise orifice in the tip together with the perforated plate—produces the spray needed for efficient combustion and proper flame formation. The pump and valve control how hard the fuel is pushed, but they don’t atomize it by themselves; the atomization action comes from the tip working with the sprayer plate.
