Method of converting a furnace from air-fuel burners to oxygen-fuel burners and oxy-fuel burner block assembly

摘要

A method has been developed for converting a hot, operating furnace to oxy-fuel avoiding the problems of the past. This method comprises removing an old burner from the furnace, drilling a cylindrical hole, with its axis generally aligning with the axis of the opening in the old burner block, through the old burner block, removing the cut out portion, inserting a refractory tube in the new hole, and fastening an oxy-fuel burner onto the furnace to join in a sealing and or biased relationship with the outside end of said tube.
