A mechanical atomizing burner uses high pressure oil that passes through what component?

The correct component through which high-pressure oil passes in a mechanical atomizing burner is the burner nozzle.

In mechanical atomizing burners, the burner nozzle is specifically designed to create a fine mist or spray of the fuel by forcing it through a restricted opening. This process utilizes high pressure to atomize the oil into small droplets, which greatly enhances the combustion efficiency when mixed with air. The design of the nozzle is crucial as it impacts the fuel droplet size and spray pattern, both of which are essential for achieving optimal combustion characteristics and maintaining a stable flame.

The alternative components mentioned serve different purposes. The sprayer plate is not typically used in this type of burner, as it may pertain to other types of atomization systems. Fuel lines transport the oil from the storage or delivery system to the burner but do not directly atomize the fuel. The mixing chamber is where the atomized fuel is combined with air, but again, it does not serve the function of atomization itself. Hence, the burner nozzle is the key component associated with the atomization process in this context.
