Abstract

"PROCESSO PARA REALIZAçãO DE COMBUSTãO EM UM FORNO POSSUINDO PAREDES POROSAS". Esta invenção refere-se a um processo para a realização de combustão em um forno possuindo paredes porosas com uma grande área superficial compreendendo a provisão de uma zona de combustão contendo uma atmosfera de gases o forno. Uma corrente de oxidante de baixa velocidade é injetada através de pelo menos um lado de injeção de oxidante das paredes porosas para dentro da zona de combustão e a corrente de oxidante é misturada com os gases o forno em uma zona de misturação dentro da zona de combustão para produzir uma mistura oxidante. Uma corrente de combustível é injetada através de pelo menos um lado de injeção de combustível adjacente ao lado de injeção de oxidante na zona de combustão. A mistura oxidante é misturada com a corrente de combustível para formar uma mistura de combustível-oxidante.
