Abstract

métodos para formar e manter um jato de gás coerente no interior de um vaso e para operra um vaso metalúrgico contendo metal em fusão. um método para operar um vaso a vácuo com um jato coerente no qual condições de vácuo são estabelecidas no interior do caso e um invólucro de chama ancorado ou afixado resultante de combustível e oxidante à velocidade subsônica ser fornecido de pelo menos uma corrente de gás supersônica. outro aspecto da invenção reside em um método para formar e manter um jato de gás coerente no interior de um vaso no qual condições a vácuo são estabelecidas, fornecer combustível e oxidante a uma velocidade subsônica ao interior do vaso em torno da dita corrente, e efetuar a combustão do combustível e oxidante para formar um invólucro de chama em torno da corrente de gás para formar e manter a dita corrente de gás como um jato coerente.
