Abstract: A forced draft, radiant wall, fuel burner, comprises a burner constructed with a central circular pipe for the conduction of pressurized combustion air, a second larger diameter pipe coaxial with the air pipe, with pressurized gas supplied to the closed annular space between the two pipes. The inner pipe extends forwardly beyond the end of the outer pipe. Fuel orifices are drilled in the forward end of the annular space, so that the gas flow will be parallel to the axis of the pipes. A second series of gas orifices are drilled through the outer wall of the second tube so that the gas glow is radial along the front of the burner tile. A plurality of air orifices are drilled radially in the forward end of the air pipe, so that the air flow is radial and directed perpendicularly against the principal longitudinal gas flow. The air tube spreads conically outwardly at its forward end.
