What is the primary purpose of the atomizing cup/spinner in an oil burner?

The primary purpose of the atomizing cup or spinner in an oil burner is indeed combustion. The atomizing cup or spinner plays a crucial role in breaking down the fuel oil into small droplets, which significantly enhances the mixing of fuel with air. This finely atomized fuel allows for a more efficient and complete combustion process when it enters the combustion chamber.

When the oil is atomized, it ensures that a larger surface area of the fuel is exposed to the air, facilitating better burning characteristics and promoting a hotter flame. This is essential for achieving the necessary temperatures for effective heating and energy production, allowing the burner to operate efficiently and reduce emissions from incomplete combustion.

In summary, the atomizing cup or spinner is integral to the combustion process in an oil burner by optimizing fuel and air mixture, which is critical for effective heating applications.
