ABSTRACT:
An improved premix-type burner for a gas-fired metal processing furnace includes a burner insert externally adjustable over a stepless continuum. The burner insert includes a helical thread disposed on its outer diameter which cooperatively engages with a helical thread disposed on an inner diameter of the burner body bore. Rotation of an adjustment tube, which extends into the burner body and is affixed to the burner insert concentrically disposed therein, causes axial translation of the burner insert, thereby regulating fuel flow to the combustion chamber and controlling the combustion process.
