Abstract

"PROCESSO PARA A RECUPERAçãO DE CALOR DE GASES QUENTES DE CONDUTO DE GASEES PRODUZIDOS PELA COMBUSTãO DE UM COMBUSTìVEL COM UM OXIDANTE EM UM FORNO". Um forno é porpocionado possuindo pelo menos dois leitos regeneradores para recuperação de calor. Enquanto um primeiro leito está sendo usado pelos gases quentes do contudo de gases produzidos pela combustão de um combustível e um oxidante dentro do forno, um segundo leito é esfriado através da realização de uma reação química endotérmica dentro dele, por exemplo a reação de reforma de um hidrocarboneto com vapor de água e dióxido de carbono e/ou a dissociação de um hidrocarboneto. Tendo sido esfriado o segundo leito pela reação endotérmica, os gases quentes do conduto de gases são redirecionados para ele enquanto que o primeiro leito, agora quente, é utilizado para realizar a reação química endotérmica. Depois o ciclo é repetido.
