Abstract (en)
[origin: EP3266855A1] Provided are briquette coal, a method of manufacturing briquette coal, an apparatus for manufacturing briquette coal, a method of manufacturing molten iron, and an apparatus for manufacturing molten iron. The briquette coal is inputted into and quickly heated in a dome portion of a melting and gasifying furnace in an apparatus for manufacturing molten iron that includes i) a melting and gasifying furnace into which reduced iron is inputted, and ii) a reducing furnace connected to the melting and gasifying furnace to provide the reduced iron. The method of manufacturing briquette coal includes i) providing powdered coal; ii) mixing a powdered cellulose ether compound with the powdered coal and providing a mixture; iii) adding water to the mixture and mixing the mixture with the water; and iv) molding the mixture and providing briquette coal. In the providing of the briquette coal, the amount of cellulose ether compound contained in the briquette coal is 0.7 wt% to 2.0 wt%.
