One of the targets in the SCOPE21 (Super Coke Oven for Productivity and Environmental Enhancement toward the 21st Century) process was to improve the productivity. To achieve high productivity, the process was applied the following items; (1) ultra super dense brick, (2) thin wall (70mm), (3) preheated coal charging, (4) medium temperature carbonization. As 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 NO_x in the exhaust gas and uniform heating were clarified. The carbonization oven of the pilot plant was designed based on these results. The combustion targets for the low NO_x and uniform heating were achieved in the test operation.
