OXY FUEL FIRING FOR OEFEN BY MEANS OF TURBULENT FLAMES AT LOW SPEED

摘要

An oxygen-fuel firing system for a furnace comprising separate, spread apart nozzles for introducing gaseous streams of oxygen and fuel into the furnace at spaced apart locations. The gaseous streams merge within the furnace away from the furnace walls and crown. Thus, the main combustion within the furnace takes place in the central portion of the furnace where a broad flame cloud is created. The broad flame cloud provides a more uniform temperature profile within the furnace for a more efficient processing of materials being melted in the furnace.
