Abstract
A burner utilizing a low pressure fan for atomizing oil and supplying air for combustion. The burner includes an air-tube, an air-atomizing nozzle disposed in the air-tube, a conduit for supplying oil to the nozzle, and a fan for supplying air to the air-tube. A back plate, a retention plate, and a side ring meter primary air to the nozzle and provide a chamber through which secondary air passes around the nozzle. The side ring is provided with a plurality of apertures for directing secondary air inwardly into a chamber desirably normal to the direction from which the secondary air is discharged therefrom. Also disclosed is a novel three-piece air-atomizing nozzle.
Claims6
A three-piece air-atomizing nozzle comprising:
- a fuel distributor having an oil passageway extending therethrough, said fuel distributor having a discharge end having at least one aperture extending from said oil passageway and opening onto an outer surface of said discharge end, wherein said fuel distributor has a cylindrically-shaped inner portion and conically-shaped outer portion, and wherein said aperture of said fuel distributor opens onto said cylindrical portion;
- a tubular outer body attachable to said fuel distributor and spaced from said discharge end of said fuel distributor to define a primary air passageway, said outer body having at least one inlet for receiving primary air into, and at least one outlet for discharging primary air from, said air passageway;
- and
- a swirler extending between said outer body and said discharge end of said fuel distributor, said swirler spaced-apart from said discharge end of said fuel distributor to define an oil atomizing passageway, said swirler having at least one inlet for receiving a first portion of the primary air into said oil atomizing passageway and an atomized oil discharge outlet, and said swirler having a plurality of vanes spaced between said swirler and said outer body for imparting a swirling motion to a second portion of the primary air.
