How does the oil spray entering the combustion chamber burn?

The correct understanding of how the oil spray entering the combustion chamber burns is that it occurs in suspension, which refers to the oil mist being dispersed throughout the air in the combustion chamber. When the oil is sprayed through the burner nozzle, it atomizes into small droplets that mix with the air. This atomization is crucial for efficient combustion, as the smaller the droplet size, the more surface area is available for the oil to vaporize and mix with oxygen in the air.

The combustion process involves the vaporization of these fine droplets at high temperatures, which leads to a more complete and efficient burn, producing heat and minimizing unburned fuel or emissions. Therefore, recognizing that the oil suspension allows for optimal mixing with air is essential for understanding why this method of burning is employed in oil burner systems.
