Abstract
PURPOSE: To produce a gas of a low CO2 content by forming a combustion chamber for burning coke, coal, linestone and pulverized coal, and a heating zone constituted of a coke-filled layer before it.
CONSTITUTION: Oxygen 7, steam 8 and pulverized coal 9 are fed via a tuyere 1, and coke 14, linestone 15 and coal 10 are fed via a feeding inlet 2 to a combustion chamber (a), where they are gasified to produce a combustion gas primarily composed of CO and H2 and a molten slag consisting of a mixt. of an ash in the coal and slaped line formed by thermal decomposition of the linestone. The gas is introduced to a heating zone (b) filled with coke and after CO2 in the gas is converted into CO by reaction with the coke, flowed into a melting zone (c) constituted of a layer filled with reduced iron 11 fed via a feeding inlet 3 to melt the reduced iron, and then recovered via a gas outlet 4. The molten, reduced iron is dropped to the heating zone (b) and after reducing FeO and SiO2 in the molten slag, collected in a molten iron reservoier (d) and discharged via a slag outlet 5.
