Abstract: A galvanizing furnace comprises a plurality of burners arrayed parallel to the surface of sheet iron to be galvanized and having burner nozzles directed upwards so that flame exiting the burner nozzles forms a screen-like wall of flame opposite and parallel to the sheet iron as the sheet iron passes through the alloying furnace. Preferably, the burners are separated into a plurality of blocks which can be controlled independently.
