Abstract

"UNIDADE PARA INJETAR UM GáS PRINCIPAL DENTRO DE UMA ZONA DE COMBUSTãO DE FORNO E PROCESSOS PARA INJETAR GáS DENTRO DE UMA ZONA DE FORNO E PARA QUEIMAR COMBUSTìVEL E OXIDANTE NA ZONA DE COMBUSTãO". Um sistema e processo para proteger um bocal que injeta um gás principal de elevada velocidade dentro de um forno ou de uma zona de combustão. O bocal está localizado em uma passagem rebaixada da abertura da porta de saída da passagem que se comunica com a zona de combustão. Gás de purga é inserido dentro da passagem a montante do bocal. O volume de gás de purga é maior do que 50% do volume total de gás principal e gás de purga e o gás de purga apresenta uma velocidade de pelo menos 3,048 m/s evitando deste modo que gases do forno entrem na passagem e ataquem o bocal.
