The front face (21) comprises a central aperture (23) corresponding to the discharge end of the burner, a front side wall (24) and a backside wall (25) spaced by one or more baffles (26) defining a coolant flow path with a coolant inlet (30) and a coolant outlet (31). The front side wall (24) and the one or more baffles (26) are made of a single piece of metal and the backside wall (25) is welded on the free top ends of the one or more baffles. The front face can for example be made of a steel according to UNS N07718.
A method for manufacturing a front face for protecting the discharge end of a burner with two or more coaxial channels, the front face comprising a central aperture corresponding to the discharge end of the burner, a front side wall and a backside wall spaced by one or more baffles defining a coolant flow path with a first end provided with a coolant inlet and a second end having a coolant discharge outlet wherein the front side wall and the one or more baffles are made of a single piece of metal and wherein the backside wall is welded on the free top ends of the one or more baffles.
