摘要:
A remotely controllable gaseous fuel burner having a burner body with a fuel inlet, a fuel outlet, and a constricted throat region immediately upstream of the fuel outlet. A concentrically disposed and longitudinally movable fuel conduit is disposed within the burner body forming an annular region between the burner body and the fuel conduit. The fuel conduit having a conduit fuel outlet forms a conduit fuel inlet in a wall of the fuel conduit. The outer surface of the conduit fuel outlet immediately upstream of the conduit fuel outlet is tapered and has an outside diameter larger than the inside diameter of the constricted throat.
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.
