8th International Congress on Science and Technology of Ironmaking - ICSTI 2018

In COURSE50 STEP2, integrated verification tests of the mitigation of CO2 emissions and CO2 separation from blast furnaces are being conducted using a newly built 12m3 experimental blast furnace and a 30-t-CO2/day chemical absorption process evaluation plant simultaneously. The experimental blast furnace was constructed in Kimitsu Works and the construction was completed in September 2015. The experimental blast furnace is equipped with 3 tuyeres and 1 taphole. An injection lance is equipped on each tuyere with the ability to inject pulverized coal, oxygen and reducing gases (COG or other gases). For the hot blast production, 2 top combustion hot furnaces were installed. The maximum blast temperature is 1,100 degrees C. The material handling facility has the capacity to charge 1 kind of coke, 2 kinds of ores and 2kinds of flux. A distributing chute is used to distribute the material into the blast furnace. A hydraulic taphole opener, mud gun and cover traverser are installed in the cast house. The hot metal and slag, produced in the operation, are received in a pot and cooled into solids before removing the metal and slag from the pot. We have performed 4 experimental campaigns with this experimental blast furnace and have had excellent results.
