What is called the air that contacts the oil before it leaves the nozzle?

Secondary air

Pre-air

Primary air

The air that contacts the oil before it leaves the nozzle is referred to as primary air. This is crucial in the combustion process for low pressure boilers, as it helps create an optimal mixture of fuel and air. When oil is being atomized by the nozzle, primary air mixes with the fuel to ensure that it is adequately dispersed, allowing for better combustion efficiency and reducing the likelihood of incomplete combustion, which can lead to undesirable emissions.

Primary air is specifically vital as it plays a role in the initial phase of combustion. The mixing process enhances the burning characteristics of the oil, making the combustion process more efficient and effective. By understanding the role of primary air, operators can better manage the combustion systems in boilers, contributing to safer and more efficient operations.
