Abstract

MÉTODO PARA SUPRIR MATÉRIA-PRIMA PARA UMA USINA DE SÍNTER E MÉTODO DE OPERAÇÃO DE UMA USINA DE SÍNTER. A presente invenção se refere a um método para suprir matéria-prima para uma usina de sínter (20). A fim de facilitar um processo de sinterização com reduzido consumo de combustíveis fósseis, a invenção provê que um material misturado (7, 8) seja usado para suprir matéria-prima, em que o material misturado (7, 8) compreende material contendo ferro particulado (1) e biomassa pirolisada particulada (2) em forma misturada, em que o dito material contendo ferro (1) é preferivelmente minério de ferro (1) e/ou a dita biomassa pirolisada (2) é preferivelmente carvão vegetal (2).
