对高炉喷煤富氧的一些关键问题作了理论与实际的探索,作出各种因素节能的量值计算分析。提出了双高纯制氧机降低纯度操作的观念及其节能值比较,并规划了“合中有分、一网两系”的供氧系统基本模式,可供各厂因地制宜参考。图17表16参30。本部分(下)继续论述关于炼铁供氧的问题,有变压吸附制氧装置、PSA+ASU制氧装置、用99．6%纯氧给高炉喷煤供氧的可行性、喷煤富氧富到多少为合适、富氧氧气从高炉鼓风机入口供入还是机后压入好,喷煤用制氧机的位置设置,以及制氧机供氧管系的基本模式,最后提出了四点结论。
Made some theoretical and practical explorations on some key issues of blast furnace pulverized coal enrichment and oxygen enrichment, and made various calculation and analysis of energy conservation for various factors. The idea of reducing the purity of double high purity oxygen generator and the comparison of its energy saving value were put forward. The basic pattern of “oxygen supply system with two points and one network and two systems” was also planned, which could be used as reference for each plant according to local conditions. Figure 17 Table 16 参 30. This part (the second) continue to discuss the issue of iron supply oxygen, pressure swing adsorption oxygen plant, PSA + ASU oxygen plant, with 99.6% pure oxygen to the blast furnace oxygen supply feasibility of coal injection Oxygen rich to the appropriate number of oxygen-rich oxygen from the blast furnace blower inlet into the machine or press into the good, the location of the oxygen injection machine with coal injection, as well as the basic model of oxygen supply pipe system, and finally made four points in conclusion.
