Abstract

resumo “injetor de combustível para um motor de turbina a gás para dois combustível e método de operação de um motor de turbina a gás para dois combustíveis” a presente invenção relaciona-se a um injetor de combustível (30) incluindo uma trajetória de fluxo para mistura ar-combustível para um combustor (50) se estendendo longitudinalmente através do injetor de combustível. o injetor de combustível também pode incluir uma galeria de combustível líquido (56), que circunda, pelo menos parcialmente, a trajetória de fluxo. a galeria pode incluir uma pluralidade de dutos radiais de combustível (54a-54c) configurada para suprir combustível líquido da galeria para a trajetória de fluxo. o injetor de combustível também pode incluir um alojamento anular externo (47) posicionado circunferencialmente em torno da galeria para formar uma cavidade isolante de ar (60) que circunda, pelo menos parcialmente, a galeria. o alojamento externo pode incluir pelo menos um furo de drenagem (62a, 62b, 62c) para prover comunicação entre a cavidade isolante de ar e a parte de fora do alojamento externo do injetor. 1/1
