Abstract

resumo patente de invenção: "restritor de fundido resfriado em bica de fundido resfriada para interromper o fluxo de fundido da caldeira". a presente invenção refere-se a uma quantidade ou nível de explosões como um resultado de fundido quente de uma caldeira de recuperação de moinho de celulose que causa um impacto no líquido frio em um tanque de dissolução é reduzida mais efetivamente ao regular o fluxo de fundido através de uma montagem de restritor. a montagem de restritor pode ser posicionada para permitir que o fundido flua, sem restrições, a partir da caldeira de recuperação até o tanque de dissolução, ou a montagem de restritor pode ser posicionada para bloquear total ou parcialmente o fluxo de fundido a partir da caldeira até o tanque de dissolução. em algumas modalidades, uma fonte de fluido de refrigeração pode ser acoplada à montagem de restritor para ajudar a resfriar partes da montagem de restritor quando o fundido quente estiver em contato com a montagem.
