Abstract

Patente de Invenção: "PROCESSOS E APARELHO DE DILUIçãO DE COMBUSTìVEL PARA A REDUçãO DE NO~ x~". Processo e aparelho para reduzir o conteúdo de óxidos de nitrogênio nos gases de combustão produzidos pela combustão do gás combustível e do ar de combustão introduzidos em um queimador conectado a uma fornalha. Os processos basicamente compreendem as etapas de conduzir o ar de combustão para o queimador, de prover uma câmara do lado de fora do queimador e fornalha para misturar os gases de combustão originários da fornalha com o gás combustível, de descarregar o gás combustível na forma de um jato de combustível para a câmara de mistura, de modo que os gases de combustão originários da fornalha sejam direcionados para a câmara e misturados na mesma com o gás combustível, diluindo assim o gás combustível, e de conduzir a mistura resultante de gases de combustão e gás combustível para o queimador, onde a mistura é combinada com o ar de combustão e queimada na fornalha.
