Abstract

"MÉTODO E EQUIPAMENTO DE SINTERIZAÇÃO DE FIOS PARA SINTERIZAÇÃO CONTÍNUA E REDUÇÃO PRÉVIA DE MATERIAL MINERAL PELETIZADO" A invenção concerne um método e equipamento de sinterização de fios para sinterização contínua e redução prévia de material mineral peletizado. O equipamento inclui um forno de sinterização de fios (1). O equipamento inclui ainda: -um canal de conexão (14, 15), que proporciona comunicação de fluxo de um duto de exaustão de gás inferior (8, 9) com um duto de entrada de gás ( 12, 13) , para conduzir pelo menos uma porção do aquecimento/sinterização resfriamento (V, VI), gás que sai de ( I I , I I I ) par a uma uma zona zona de de -um sensor de gás (16, 17), o qual é disposto no canal de conexão ( 14, 15) para detectar a composição do gás, um canal de escapamento de ar ( 18, 19) , o qual proporciona 20 comunicação de fluxo entre o duto de exaustão de gás inferior (8, 9) e a atmosfera, e uma válvula de escapamento de ar (20, 21), a qual se dispõe no canal de escapamento de ar (18, 19) para abertura e fechamento da comunicação de fluxo. Para tornar a composição de gás redutora, um dispositivo de controle (22) é disposto para monitorar as composições de gás detectadas pelo sensor de gás (16, 17) e, baseado nisso, controlar a válvula de escapamento de ar (20, 21), para controlar o acesso de ar proveniente da 30 atmosfera para o duto de exaustão de gás (8, 9), de modo a ajustar o teor de oxigênio do gás e/ou ajustar o coeficiente do ar de combustão de um queimador ( 7) , para ajustar o teor de monóxido de carbono do gás.
