Abstract

"APARELHO PARA INJETAR GáS EM UM VASO". Aparelho para injetar gás em um vaso que inclui um conduto de fluxo de gás (31) o qual recebe gás quente através de uma estrutura de entrada de gás (32) em uma extremidade traseira do conduto. Uma estrutura central alongada (33) estende-se através de todo o comprimento do conduto (31) e suporta uma série de aletas (34) para transmitirem redemoinho ao fluxo de gás que sai pela extremidade dianteira do conduto. A extremidade dianteira do conduto (31) tem uma ponta (36) refrigerada a água internamente e água flui para a ponta (36) e proveniente da mesma através de passagens anulares (43, 44) na parede do conduto (31). A ponta 36 compreende uma camisa oca dividida internamente por uma estrutura divisória para formar uma série de galerias de fluxo de água, cada uma delas estendendo-se circunferencialmente em torno da ponta e interligadas para escoamento de água de refrigeração sucessivamente através das galerias proveniente da passagem de suprimento de água (43) para a passagem de retorno de água (44). A estrutura divisória também proporciona uma interligação estrutural entre tubos interno e externo 37, 39 da parede de conduto para transferir força de carga gravitacional do tubo interno para o tubo externo quando o aparelho é suportado verticalmente através do tubo externo.
