Abstract
método e dispositivo para fornecer gás de redução a partir de gás gerador. a presente invenção refere-se a um método para fornecer gás de redução para redução de minério de ferro através do gás gerador de resfriamento e despoeiramento a seco (20) produzido em um gaseificador fundidor (3) para produção de ferro-gusa e, também, a um dispositivo para realizar o método. neste caso, o gás gerador (20) é resfriado tanto por injeção de água como por troca de calor com, pelo menos um meio de troca de calor líquido (14) após este ter sido descarregado do gaseificador fundidor (3) e antes do despoeiramento a seco deste.
