Abstract

Patente de Invenção: "MONTAGEM DE QUEIMADOR COM BAIXAS EMISSõES DE NO~ x~ E MéTODO PARA A REDUçãO DO CONTEúDO DE NO~ x~ DE GáS DE COMBUSTãO SUPERFICIAL". Uma montagem de queimador (20) para uma fornalha ou dispositivo semelhante tendo uma câmara de combustão definindo uma zona de combustão (24). A montagem de queimador (20) inclui uma primeira telha anular (36) definindo uma trajetória centralmente localizada para um fluxo do ar de combustão e uma segunda telha anular (38) concêntrica com a primeira telha anular. A segunda telha anular (38) tem um diâmetro interno que é maior do que um diâmetro externo da dita primeira telha anular (36), e a segunda telha anular (38) é posicionada em relação circundante relativa a pelo menos uma porção da dita primeira telha anular (36), de modo que um conduíte em formato de anel (80) é definido entre elas. A disposição é tal que o ar de combustão que está fluindo ao longo da dita trajetória induz um fluxo do gás de combustão através do conduíte para transporte pelo fluxo do ar de combustão.Invention Patent: "MOUNTING THE BURNER WITH LOW NO ~ x ~ EMISSIONS AND METHOD FOR REDUCING THE NO ~ x ~ CONTENT OF SURFACE COMBUSTION GAS". A burner assembly (20) for a furnace or similar device having a combustion chamber defining a combustion zone (24). The burner assembly (20) includes a first annular tile (36) defining a centrally located path for combustion air flow and a second annular tile (38) concentric with the first annular tile. The second annular tile (38) has an internal diameter that is greater than an outer diameter of said first annular tile (36), and the second annular tile (38) is positioned in a surrounding relationship relative to at least a portion of said first annular tile (36), so that a ring-shaped conduit (80) is defined between them. The arrangement is such that the combustion air that is flowing along said path induces a flow of the combustion gas through the conduit for transport by the flow of the combustion air.
