One of the targets of the SCOPE21 process was to improve theproductivity. To achieve high productivity, the process was applied the following items; (1) ultra super dense brick, (2) thin wall (70 mm), (3) hot coal charging, (4) medium temperature carbonization. As the heat flux for carbonization was needed about 2 times as much as a conventional coke oven, the combustion technologies to achieve high productivity were investigated by using the actual scale combustion test oven. The combustion conditions to achieve low NOx in the waste gas and uniform heating for carbonization were clarified. The coke oven of the pilot plant was designed based on these results. The combustion targets of the low NOx and uniform heating were achieved in the test operation.
