立春已过，龙城太原暖意渐升。 2月12日，潞安化工机械（集团）有限公司生产车间里，焊花闪烁、机器轰鸣，4台气化炉正在生产线上加工。 "这个大块头，一天能吃掉1500吨'三高'煤，吐出来的是一氧化碳和氢气占比80%以上的合成气，这是化工产业的重要原料。"市场技术开发中心副主任贾雷 拍了拍身边巨大的炉体，"今年下半年，这台晋华炉3.0就要交付客户了。" 潞安化工机械（集团）有限公司总工程师仙运昌介绍："劣质煤的灰熔点动辄超过1500摄氏度，而传统耐火砖气化炉最高只能耐受1250摄氏度，煤进去烧不 成液态渣，反而像粘稠的牙膏一样糊在炉壁上，设备难以稳定运行。" 刚从车间出来，贾雷直奔清华大学山西清洁能源研究院，"有几个关键参数，需要和科研团队再确认一下。" 自2001年起，清华大学、清华大学山西清洁能源研究院就与山西企业组建起产学研联盟，探索中国自主的煤气化技术。 会议室里，清华大学山西清洁能源研究院碳基原料清洁转化及利用中心的工程师们正与贾雷围坐在一起，对着气化炉工艺图反复推敲。 "有时候他们来研究院，有时候我们去企业，双方一年见面二三十次也不止。"中心高级工程师张晋玲说："他们把市场的技术需求和难题反馈给我们， ...
