ABSTRACT:
A burner 10 for the edge heating of strip metal travelling between a furnace and a rolling mill comprises a body 12 having two chambers 16, 18 separated by a dividing wall 14. A multiplicity of square tubes 24 connect the first chamber 16 with an upper surface 26. The tubes 24 project through the second chamber and are located in corresponding circular holes 30 such that a gap is provided around the tube. The first chamber 16 has gas inlets 20, provided with baffles to ensure dispersion of the gas within the chamber 16, and the second chamber 18 is provided with oxygen inlets 28. Thus a gas entering the first chamber 16 via the inlet 20 and leaving through the tubes 24 mixes with the oxygen on the upper surface 26, the oxygen leaving the body 12 via the holes 30. A cooling jacket 34 supplied with cold water acts as a barrier to increase flame stability and cool the burner which can heat up due to back radiation from the surface to be heated.
