The effects of hydrogen gas on the reduction rate of ore and reactivity of coke were estimated by using the Boris type movable reaction furnace shaft inner reaction simulator (SIS). The temperature profile was controlled to reproduce the shaft region in the actual blast furnace, and the gas composition was self-controlled inside the reaction tube. The apparent gas utilization ratio was also affected by carbon activity.

使用高炉井内反应模拟器估算 H2 气体利用率

氢气对矿石还原率和焦炭反应性的影响是通过使用鲍里斯型移动反应炉竖井内反应模拟器（SIS）来估算的。控制温度分布以再现实际高炉中的竖井区域，并且反应管内的气体成分是自我控制的。表观气体利用率也受碳活性的影响。
