Abstract

Patente de Invenção: <B>"PREAQUECEDOR DE MATERIAL DE CARREGAMENTO, COM PORçõES DE PAREDE DE ENVóLUCRO SUBSTITUìVEIS"<D>. A invenção é relativa a um dispositivo para preaquecimento de carregamento de matéria-prima para preaquecer uma carga (60) a ser carregada para o interior de um vaso de fornalha (3) e que compreende uma chaminé (9) fixada a uma estrutura (20). Na área superior a chaminé tem um furo de carregamento que pode ser fechado (61) para a carga (60) e uma saída de gás, e em sua área inferior tem uma abertura de distribuição para a carga (60) e uma entrada de gás. As paredes da chamine (33,35) delimitam uma câmara de recepção (62) para a matéria prima de carregamento (60) a ser aquecida. De acordo com a invenção, as paredes da chaminé (34, 35) são divididas em seções de parede de chaminé que são fixadas na estrutura (20) de tal modo que elas podem ser trocadas individualizadamente.
