Which type of oil burner is utilized when oil is supplied under high pressure?

A mechanical atomizing burner is used for oil supply under high pressure due to its design and operational principles. This type of burner functions by using a mechanical method to create a fine mist or atomization of the fuel oil, achieved through high-pressure pumps that push the oil through a nozzle. This process ensures complete combustion, leading to more efficient and effective heating.

Mechanical atomizing burners are ideal for applications where high pressure is available and can help in achieving better control over the fuel-air mixture, resulting in reduced emissions and better overall performance. In contrast, other burner types like air atomizing burners rely on air to help atomize the fuel at lower pressures, while gravity burners may not be suited for high-efficiency applications due to their reliance on gravity to feed the fuel without the high-pressure capability necessary for atomization. Low-pressure burners, as the name suggests, work best in situations where lower oil pressure is applied.

Thus, the selection of a mechanical atomizing burner is justified in scenarios requiring high oil pressure to ensure optimal combustion efficiency and performance.
