数据集使用建议 在使用煤基直接还原（Coal-DRI）路线的生命周期清单（LCI）数据时，请确保数据适用于您评估的特定地理位置和技术背景。LCI数据应与中国示范项目的平均运行数据一致。对于COG-DR和H-DR路线，由于这些过程的数据是基于Coal-DRI与文献数据结合估算的，因此可能需要额外的验证。由于技术和规模外推的风险，对这些路线进行大型工业应用的预测应谨慎进行。
产品或过程的技术目的 煤基直接还原铁（Coal-DRI）生产过程通常用于钢铁制造业，从铁矿石中获得不需要熔化矿石的金属铁。该过程使用非炼焦煤作为还原剂，对氧化铁进行固态还原。生产出的直接还原铁常用作电弧炉的原料，在钢厂中被熔化以生产钢材。
