Abstract

MISTURADOR DE FLUIDO COM MúLTIPLAS ALTURAS E MéTODO PARA A UTILIZAçãO DO MESMO. A presente invenção refere-se a um conjunto de misturador (204, 603) para misturar o ar de entrada a partir do sistema de entrada (124) com gás de descarga de um sistema de recirculação de gás de descarga (134) para render uma corrente de mistura inclui um conduto de ar de entrada (202,700) tendo uma entrada (206,706) conectada, de modo fluido, a um sistema de entrada. O conjunto misturador (204,603) também inclui um misturador (200, 600) tendo uma entrada (208,702) conectada, de modo fluido, ao sistema de recirculação de gás de descarga (134). O misturador (200, 600)é pelo menos parcialmente disposto no conduto de ar de entrada (202,700) e inclui um tubo externo (203,604) e uma parte de divisão (217, 602) disposta dentro do tubo externo. A parte de divisão (217, 602) divide uma primeira passagem (216, 612) de pelo menos uma segunda passagem (218, 608), a primeira passagem tendo uma descarga (216, 612') que está a uma primeira altura, a segunda passagem tendo uma descarga (218, 608)que está a uma segunda altura.
