Combustion apparatus for burning waste oils of various viscosities with high combustion efficiency and which can meet strict pollution regulations comprises primary and secondary combustion chambers with the secondary combustion chamber located above the primary combustion chamber and the primary combustion chamber located within an outer housing so as to define between the outer housing and the primary combustion chamber a plenum space. An air blower delivers air to the plenum space which feeds air into the primary combustion chamber through air inlet openings in its side wall. The primary combustion chamber has a burner bowl provided at its base and a burner ring disposed above the burner bowl. Oil is supplied at a constant rate to the burner bowl via a positive displacement pump. The burner ring features a central aperture and two concentrically disposed rings of orifices with the orifices of the outer ring being of larger diameter than the orifices of the inner ring. The air inlet openings in the sidewall of the primary combustion chamber comprise a first set located below the burner ring and a second set located adjacent the top edge of the primary combustion chamber above the burner ring. The second set of air inlet openings are preferably relatively smaller and more numerous than the first set. In operation the oil supplied to the burner bowl vaporizes and the flame pattern produced by the burner ring cooperates with the arrangement of air inlet openings to produce stable burning conditions for a wide variety of fuels.
