对某焦化公司进口的印尼焦煤、肥煤、1/3焦煤以及国内同牌号的田庄焦煤、两渡肥煤和枣庄1/3焦煤进行煤质及单种煤结焦性对比分析,并以生产常用配比为基础进行20 kg实验焦炉配煤炼焦实验,探讨印尼煤与国内炼焦煤的配伍性能。结果表明,印尼煤均是低灰、低硫、强黏结性、高膨胀性、低流动性的单一煤,其活性高,活惰比均不低于24,而国内炼焦煤有一定的混配,其活惰比为1~2,活性组分和惰性组分含量较为均衡;印尼单种煤所制焦炭的强度和热性能较差;印尼煤替代国内同牌号煤进行配煤炼焦,所制焦炭质量明显下降,并且替代量越大,焦炭质量下降越多。
對某焦化公司進口的印尼焦煤、肥煤、1/3焦煤以及國內同牌號的田莊焦煤、兩渡肥煤和棘莊1/3焦煤進行煤質及單種煤結焦性對比分析,併以生產常用配比為基礎進行20 kg實驗焦爐配煤煉焦實驗,探討印尼煤與國內煉焦煤的配伍性能。結果錶明,印尼煤均是低灰、低硫、彊黏結性、高膨脹性、低流動性的單一煤,其活性高,活惰比均不低于24,而國內煉焦煤有一定的混配,其活惰比為1~2,活性組分和惰性組分含量較為均衡;印尼單種煤所製焦炭的彊度和熱性能較差;印尼煤替代國內同牌號煤進行配煤煉焦,所製焦炭質量明顯下降,併且替代量越大,焦炭質量下降越多。

Indonesian coking coal ,fat coal and 1/3 coking coal imported by a certain coking company were compared with the same sort of domestic Tianzhuang coking coal , Liangdu fat coal and Zaozhuang 1/3 coking coal in coal property and coking property .The common coal blending ratio was followed in coal blending for coking experiment in a 20 kg coke oven ,in order to find out the compati-bility of Indonesian coal with domestic coking coal .The results show that the Indonesian coals are sin-gle with low ash ,low sulfur ,strong bonding ,high expansibility ,and low liquidity ,and they also have high activity with the live-idle index reaching as high as more than 24 while domestic coking coals are mixed and more balanced with the live-idle index at 1 to 2 .The coke produced from Indonesian coal has low strength and poor thermal property .If the domestic coal is replaced by Indonesia coal , the quality of coke produced will decrease in quality sharply ,and the more replaced ,the greater de-crease in the coke quality .
