The topic of this technology-design is yearly 1.10 million tons cokes with tamping coking technology. And the design refers to the mature coking technology of the Hebei Iron and Steel Group Jiujiang Wire Co., Ltd. The coal blending ratio is: gas coal 40%, 1/3 coking coal 25%, fat coal 10%, coking coal 10% and lean coal 15%. The material balance computation and energy balance computation of coke oven is the main content. As a result, the annual consumption of dry coal was 1.4455 million tons, the annual output of main products: 1.1016 million tons of cokes, 54.8 kilotons of coal tar, 16.5 kilotons of crude benzene, 3.3 kilotons of ammonia and 232.9 kilotons of clean gas. Tons of coal into the coke oven will be consume coke oven gas 140.34m3, and the thermal efficiency is 76.12%. In the aspect of the selection of coke oven model, the design used the HXDK55-08F tamping coke oven. The carbonization chamber is 5.5m in height. Acc
