Geyseric burner assembly and method for combusting fuels

摘要

Disclosed herein is a geyseric burner assembly for selectively and efficiently burning either oil or a gaseous fuel therein and discharging the combustion flow in an axial direction. The burner assembly includes a plurality of concentric shells defining an outer housing, a plenum which communicates with a forced air supply and an air passageway which delivers air for combustion from the plenum along the interior shells where the air is preheated to a toroidally shaped mixing ring which is disposed on an inclined floor about a gas pilot nozzle. Oil or gaseous fuel is selectively introduced to the burner toward the mixing ring where it mixes in a rolling or turbulent geyseric motion with the inflowing air resulting in instantaneous ignition and combustion.
