Abstract

Patente de Invenção: <B>"MéTODOS DE DILUIçãO DE COMBUSTìVEL E APARELHO PARA A REDUçãO DE NO~ X~"<D>. São providos métodos e aparelhos para a redução do teor de óxidos de nitrogênio nos gases de combustão produzidos pela combustão de um gás combustível e de um ar de combustão introduzido em um queimador (36) conectado a um forno (34). Os métodos, basicamente, compreendem as etapas de condução do ar de combustão para o queimador (36), provisão de uma câmara (10) fora do queimador (36) e do forno (34), para mistura de gases de combustão do forno (34) com o gás combustível na forma de um jato de combustível para a câmara de mistura (10), de modo que os gases de combustão do forno (34) sejam retirados para a câmara (10) e misturados e diluam o gás combustível ali, e condução da mistura resultante de gases de combustão e gás combustível para o queimador (36), onde a mistura é combinada com o ar de combustão e queimada no forno (34).
