Abstract (en)
[origin: WO0163176A1] A burner assembly (20) for a furnace or like device having a firebox defining a combustion zone (24). The burner assembly (20) includes a first annular tile (36) defining a centrally located path for a flow of combustion air and a second annular tile (38) concentric with the first annular tile. The second annular tile (38) has an internal diameter which is larger than an external diameter of said first annular tile (36), and the second annular tile (38) is positioned in surrounding relationship relative to at least a portion of said first annular tile (36) so that a ring-shaped conduit (80) is defined therebetween. The arrangement is such that combustion air flowing along said path induces a flow of flue gas through the conduit for entrainment by the flow of combustion air.
