Abstract:

The running condition of stamp-charging coke oven modified from 4.3m top-charging coke oven is respectively evaluated from the aspects of coal blending cost, production equipment, environmental protection and process, after modification the cost of coal blending is lowered by 50~180 RMB yuan/t coke, both production failure time and equipment failure time are respectively postponed by 10.7 time and 3.3 time, meanwhile K2, Kb and Kc are lowered to different extent, under the premise of ensuring that oven wall is not damaged, its index of coke strength after reaction is slightly lower than that of originally-designed stamp-charging coke oven.
