In a pressure atomizing fuel oil burner, what component is responsible for atomization of fuel oil?

In a pressure atomizing fuel oil burner, the atomization of fuel oil is primarily achieved through the burner tip in conjunction with high fuel oil pressure. When fuel oil is forced through the burner tip at high pressure, it exits as a fine mist or spray, which maximizes surface area for combustion. This process is essential for efficient burning, as it allows the fuel to mix more effectively with the air supplied by the burner fan.

The burner fan, while crucial in providing the necessary air for combustion, does not participate directly in the atomization of the fuel. Similarly, the fuel pump's role is more about delivering fuel to the burner under the appropriate pressure rather than the actual process of atomization. The atomizing chamber also contributes to the reduction of fuel droplet size but is not the primary mechanism for achieving the atomized state itself. Therefore, the combination of high pressure fuel oil and the burner tip is the key factor in achieving effective atomization in this type of burner.
