Abstract

A burner for a bottom fired, ingot heating furnace producing faster and more even heating with lower fuel consumption is disclosed. The burner includes a plurality, preferably three, upstanding nozzles having nozzle ports directed at essentially a right angle to a radial line extending from the burner center. This orientation imparts a circular swirling action of the combustion gases which produces faster and more even heating of ingots contained within the furnace. The nozzle is arranged with a nozzle cap which shields the entire nozzle top from debris falling from the furnace roof resulting in a greatly extended service life.
