Which types of nozzles are used in oil burners?

The correct answer highlights the various types of atomizing nozzles used specifically in oil burners, which play a crucial role in efficiently mixing oil with air to create a combustible mixture. Understanding these types of nozzles is essential for optimizing the combustion process, enhancing efficiency, and minimizing emissions.

Rotary atomizing nozzles utilize a spinning mechanism to create a fine mist of fuel, allowing for better air-fuel mixing and more efficient combustion. Steam atomizing nozzles rely on steam pressure to atomize the oil, which is particularly useful for heavier oils that require assistance in achieving a fine spray. Pressure atomizing nozzles create a spray using high fuel pressure, facilitating efficient burning by ensuring that the oil is well-distributed in the combustion chamber.

While other options mention nozzles with various functionalities, they do not specifically address the atomization process critical for oil burners. This atomization is vital for achieving optimal combustion and meeting performance standards, making the second option the most relevant in this context.
