炼铁生产过程中产生的高炉煤气可有效地用作发动机燃料，为大多数中小型钢铁企业发电。利用GT-POWER软件模拟了高炉煤气不同组分、压缩比和点火时刻对高炉煤气燃烧特性的影响。结果表明，随着一氧化碳和氢气比例的增加，火焰速度和燃烧速率增大。存在一个最佳压缩比值，在此值下燃烧速度最大。在一定范围内，适当增大点火提前角可以改善燃烧性能。仿真结果与实验结果的对比表明，该方法具有较好的预测效果.这些结果有助于优化影响燃烧的参数，为高炉煤气发动机的进一步研究提供一定的参考。
Blast-furnace gas produced from the process of iron making effectively can be used as fuel for engines to generate electricity for most middle and small steel enterprises. The effects of different component of blast-furnace gas, compressive ratio and ignition timing on combustion property of blast-furnace gas are simulated by GT-POWER software in this paper. The results show that flame speed and combustion rate will increase with the proportion of carbon monoxide and hydrogen increasing. There will be an optimized compression ratio value, under which the burning velocity is maximum. Within a certain scope, increasing ignition timing angle appropriately can improve property of combustion. A comparison of simulation and experiment result shows that the predictions give good results. All these results can help to optimize the parameters that affect the combustion, and provide certain reference for the further study blast-furnace gas engine.
