Abstract
A blast furnace is fed by a charge of conventional composition and a blast is used that contains about 50% oxygen and 20% water vapour, balance nitrogen. Additional fuel in the form of coal dust and/or oil is supplied to the raceways. Normal temperatures are maintained in the hearth and top zones. As compared with conventional operation a very high specific crude iron production per m<2> of hearth area and 24 hours will result. The molecular ratio CO+H2/N2 of the top gas will be higher than 2.8 which makes the top gas suitable for ammonia production.
