["2024-09-20","无烟煤介绍","无烟煤是高变质煤，具有坚硬、光泽强等特点。燃烧时间长，火力旺。无烟煤主要用于化肥、化工生产。阳泉无烟煤因具有可磨好的特点，是理想的高炉喷吹用燃料。晋城、阳城一带的无烟煤被称为兰花炭闻名中外。山西的无烟煤资源储量大，质量好，居全国首位。","百度","煤炭","无烟煤","基本知识","科普"]
["2024-09-20","焦煤介绍","焦煤是炼焦用煤中之主焦煤，变质程度中等，结焦性和粘结性最佳。山西之焦煤所产焦炭块度大、裂纹少、抗碎强度大、抗磨性好，为炼焦用煤之珍品。利用焦煤，可得到焦炭、焦油、焦炉气。焦炭除供给冶炼外，还可造气和电石。而焦油和焦炉气可作为燃料，还能提炼数十种化工产品。山西河东煤田中、南部的离石、柳林和乡宁矿区属低硫、低灰主焦煤。所产焦炭为特优焦炭，列为全国之重点。","百度","煤炭","焦煤","基本知识","科普"]
