Oxygen-gaseous forehearth burner for air-fuel and oxy-fuel forehearth burner block geometries

摘要

An oxy-gaseous fuel burner for a forehearth system having an oxygen conduit, a fuel conduit disposed concentrically within the oxygen conduit and forming an annulus between the fuel conduit and the oxygen conduit, a precombustor conduit disposed at the oxygen outlet end of the oxygen conduit, and a fuel tip disposed at the fuel outlet end of the fuel conduit. The outlet of the fuel tip is disposed at or upstream of the inlet to the precombustor conduit.
