At what pressure does a typical oil burner operate?

A typical oil burner operates at a pressure of approximately 100 psi. This pressure is crucial because it ensures that the oil is atomized effectively to allow for proper combustion. When the oil is pressurized, it can be injected through a nozzle, where it is atomized into fine droplets. This atomization is essential for achieving efficient burning and optimal heating performance.

Operating at around 100 psi strikes a balance—too low a pressure may result in poor atomization, leading to incomplete combustion and soot formation, while excessively high pressures can cause undue stress on the burner components and potential safety issues. This standard operating pressure facilitates efficient heating and minimizes operational problems.
