Abstract

PURPOSE: To provide high-calory gas stably and efficiently, by charging coal and coke together with lime stone to burn them at a high temperature in front of an O2 blowing opening and by leading the resulting cumbustion gas into a forward layer filled with graphite shhers or low-activity coke.
CONSTITUTION: O2, steam or the like is blown in from a tuyere 1 to form a comsustion chamber 6, and coke, coal and lime stone are charged into the combustion chamber 6 from a loading aperture 2 to be furned. The resulting high-temperature combustion gas is passed through a layer filled with graphite shheres or lowactivity coke upward to melt reduced iron C charged from a loading aperture 3 for reduced iron by its sensible heat and then the combustion gas is recovered through a gas taking out opening 4. On the other hand, molten matter comprising molten ash and CaO, a component of lime stone, formed in the combustion chamber 6, and molten reduced iron flow into a hearth 5 in the bottom part of the furnace and are drawn out of a tap hole 8 and a cinder notch 9.
