What is the primary function of a fuel de-aerator?

The primary function of a fuel de-aerator is to reduce air in the oil by eliminating the need for a two-pipe system. When oil is being transported from the tank to the burner, it can pick up air, which reduces the efficiency and effectiveness of combustion. A de-aerator works by allowing the oil to flow through a chamber where air bubbles can rise to the surface and escape, ensuring that the oil delivered to the burner is free from entrained air.

By minimizing the presence of air in the fuel line, a de-aerator helps improve the stability of the oil flow and enhances combustion efficiency. This function is critical because air in the fuel can lead to incomplete combustion, increased emissions, and potential operational issues in oil-burning appliances. Thus, the de-aerator contributes to a more efficient and reliable heating system by maintaining a steady and clean supply of fuel.
