A dual fuel burner (10) for use in furnaces such as in steam cracking includes a primary air chamber, a burner tube (12) having an upstream end (16) and a downstream end (12), a fuel orifice (11) located adjacent the upstream end of the burner tube for introducing gaseous fuel into the burner tube, a burner tip (20) mounted on the downstream end of the burner tube so that combustion of the gaseous fuel takes place downstream of the burner tip, and at least one non-gaseous fuel gun, the at least one non gaseous fuel gun (200) having at least one fuel discharge orifice (204) for combusting the non-gaseous fuel downstream of the discharge orifice. The non-gaseous fuel gun is radially positioned beyond an outer diameter of the burner tip so that a flame emanating from the combustion of the non-gaseous fuel is substantially aligned in parallel with a flame emanating from the combustion of the gaseous fuel. |
