摘要:

分别从配煤成本、生产设备、环保和工艺等方面评价了改为捣固炼焦后的运行情况,改造后配煤成本降低50~180元/t焦,生产故障时间和设备故障时间导致的晚点分别增加10.7倍和3.3倍,同时K2、K均、K安都有不同程度的降低,在保证不损害炉墙的前提下,焦炭的反应后强度指标会比原设计为捣固的稍差。

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.
