Which type of nozzle is NOT used in oil burners?

In the context of oil burners, the identification of nozzles is critical for proper fuel atomization and combustion efficiency. Gas atomizing nozzles are designed to mix gas with liquid fuel to create a fine mixture, which is suitable for gas combustion. However, oil burners typically utilize liquid fuels, such as heating oil, which require a different approach to atomization.

The types of nozzles commonly used in oil burners include rotary atomizing, steam atomizing, and pressure atomizing. Each of these types works effectively with liquid fuels by breaking the liquid down into very small droplets to enhance combustion.

Rotary atomizing nozzles use a rotating mechanism to create a fine mist of oil for efficient burning. Steam atomizing nozzles utilize steam pressure to help in the nebulization of the oil, which aids in faster and more complete combustion. Pressure atomizing nozzles force the oil through a small orifice under high pressure to achieve the desired atomization.

In contrast, gas atomizing nozzles are not suitable for oil burners because they are specifically designed for a different fuel type. Using a gas atomizing nozzle in an oil burner would not provide the necessary conditions for optimal combustion of liquid fuels, making it an inappropriate choice
