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.method and device for supplying reduction gas from generator gas. The present invention relates to a method for providing reducing gas for iron ore reduction through the dry cooling and dedusting generating gas (20) produced in a smelting gasifier (3) for the production of pig iron and also , to a device to perform the method. In this case, the generator gas (20) is cooled by both water injection and heat exchange with at least one liquid heat exchange means (14) after it has been discharged from the melt gasifier (3) and before dedusting. dry of this.
