Underport firing for regenerative furnaces

摘要

Horn Glass Industries has developed a natural gas burner for underport firing at regenerative furnaces. The Dualflame advanced control burner works with an inner and outer nozzle. The burner has two adjustment possibilities: Position of the inner nozzle and gas quantity of the inner and outer nozzle. A hand wheel at the rear of the burner can control the inner nozzle. Thus, the flame can be shaped from soft and wide to sharp and strong.
