顶装炼焦改造为捣固炼焦的生产实践

介绍了JN43-80型焦炉由顶装炼焦改为捣固炼焦的改造工程,对比了改造前后炼焦用煤质量指标、配煤煤种和比例、用煤量、焦炭质量指标、化工产品回收率等。顶装炼焦改为捣固炼焦具有减少主焦煤配入量、增加气煤的配入量、提高焦炭产量等优势,通过改造,可使焦化企业降本增效。

The Practice of Top-charged Coke Oven Being Modified into Stamp-charged Coke Oven

The revamping of the model JN43-80 coke oven from the top-charged oven into the stamp-charged one was introduced.The feed coal quality,the number of coal blends,their blending ratio,coal consumption,the quality of the coke produced,the recovery ratio of the chemical products,etc.before and after the revamping were compared,which indicated that such a revamping resulted in a reduction of the main coking coal,an increase of the gas coal blend,and an increase of the coke output.The coking enterprise can thus reduce its production cost and increase its profitability.
