In a pressure atomizing burner, the atomization of the oil is accomplished by ______.

Explanation:
In a pressure atomizing burner, atomization happens at the nozzle assembly, specifically the sprayer plate and tip. The high-pressure oil is forced through a small orifice at the tip and then passes across the sprayer plate, which has calibrated openings that shear the liquid into fine droplets. This plate-tipped design shapes the spray pattern and droplet size, delivering the fuel into the combustion chamber for efficient mixing with air. The pump and hose simply supply the fuel under pressure, while gas and air are used in different burner systems to assist atomization or combustion but aren’t what directly atomizes the oil in a pressure atomizer.
