PARTICULATE INJECTION BURNER

摘要

A burner for use in an electric arc furnace in which the acceleration of a flow of fuel and primary oxidant is used to effect mixing and acceleration of a flow of particulate matter and secondary oxidant therewith. The burner is also capable of mixing andaccelerating liquid materials or slurries, in fine d roplet form. By supersonic injection of hot oxygen (superstoichiometric flame) it is possible to use the burner for decarburisation of the metal as well as post combustion. The burner can be mounted in a water-cooled box. This box can be fitted with an oxygen port for extra oxygen for post combustion while the burner injects hot oxygen and carbon for slag foaming.
