    Abstract: Le procédé selon l'invention comprend un brûleur à prémélange constitué d'un ensemble de buses (2) de prémélange disposées circulairement selon un diamètre DB autour d'une buse centrale (4) disposé sur un axe central A au brûleur (1) et destinée à créer une flamme radiale (5) caractérisée en ce que l'ensemble des buses (2, 4) a un ratio comburant/carburant (R) compris entre 1,3 et 1,75. La flamme radiale (5) a pour mission d'assurer l'inter-allumage entre les différentes buses (2, 4) de prémélange. Une flamme annulaire est également réalisée par une combustion en prémélange afin de conserver le ratio (R) favorable à la faible production d'oxydes d'azote d'origine thermique à l'intersection de la flamme radiale et des flammes issues des buses.

    Abstract: According to the present disclosure, a flat-flame nozzle is provided for producing a flat flame in a flame chamber included in a burner assembly. The flat-flame nozzle is configured to conduct fuel from a fuel supply to an ignition zone in the flame chamber. In some illustrative embodiments, the flat-flame nozzle is also configured to conduct oxygen from an oxygen supply to the ignition zone to produce a combustible oxygen-fuel mixture in the flame chamber. In illustrative embodiments, a removable first plate-separation border frame is positioned to lie between a first lower plate and a companion first upper plate. This border frame is configured to cooperate with those plates to form in the flat-flame nozzle a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet.

    Abstract: 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.
