What characteristic defines a typical "gun type" oil burner?

A typical "gun type" oil burner is characterized by the mechanism in which oil is pressurized and forced into a combustion chamber. This pressurization allows for fine atomization of the oil, creating a suitable fuel-air mixture for efficient combustion. The high-pressure oil is injected into the combustion chamber where it is ignited by a spark or flame.

This design enhances the burner’s efficiency and ensures a stable flame, thus improving overall system performance. The atomization process is crucial as it helps in mixing the fuel with air, allowing for better combustion and reduced emissions.

In contrast, while other features of oil burners may use different mechanisms, such as natural draft or various fan designs, the defining characteristic of the gun type oil burner is its reliance on pressurized oil injection into the combustion chamber.
