前言随着炼铁技术的不断发展,要求提高风温,降低吨铁能耗及成本,达到高产低耗的目的,但随着高炉燃料比的不断降低,高炉煤气发热值日趋贫化,却又限制了高风温使用的可能性。目前,本钢能源比较紧张,在炼铁焦炭和焦炉煤气严重不足的情况下,回收炼铁工艺的二次能源,有效地利 Preface With the continuous development of ironmaking technology, it is required to increase the air temperature, reduce the energy consumption and the cost of tonne iron, and achieve the goal of high yield and low consumption. However, as the fuel ratio of the blast furnace decreases, the calorific value of blast furnace gas becomes increasingly depleted, Limiting the use of high air temperature possibilities. At present, the relatively tight energy of Benxi Iron and Steel, iron coke and coke oven gas in the case of a serious shortage of recycling secondary iron smelting process, effectively
