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 toda a extensão 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). As aletas (34) são montadas na estrutura central (33) de maneira a estenderem-se até extremidades dianteiras dispostas dentro da ponta de conduto (36) e são dimensionadas de maneira tal que durante a operação do aparelho suas extremidades dianteiras são enganchadas e suportadas pela ponta de conduto (36) refrigerada a água internamente.
