Abstract

resumo “método e sistema para reduzir recessão de sílica” a presente revelação refere-se a métodos e sistemas para reduzir recessão de sílica de cerâmicas contendo silício ou compósitos de cerâmica contendo silício, particularmente aqueles expostos a um gás de combustão ou a ambientes de gás de combustão, que inclui aqueles expostos a ambientes de gás de combustão de alta temperatura. o método e sistema envolvem a dopagem com silício de ar comprimido e/ou remoção de umidade do ar comprimido antes de mesclar o ar comprimido tratado com o gás de combustão ao qual as cerâmicas contendo silício ou compósitos de cerâmica contendo silício são expostos.
