Abstract

Patente de Invenção: <B>"MéTODO PARA A EXECUçãO DE COMBUSTãO POR ESTáGIOS"<D>. Trata-se de um método de combustão por estágios aperfeiçoado utilizável com a combustão de oxigênio-combustível e em um forno que contém uma carga, sendo que a combustão estequiométrica e a injeção de oxidante secundário são levadas a efeito em uma orientação que forma uma atmosfera mais oxidante ou mais redutora próxima à superfície da carga do que seria o caso com uma atmosfera de forno homogênea.
