在高温固定床局部流态化的流体力学计算的基础上,对高炉炉腹中物料的局部流态化问题进行了推究。通过数学模型,参以实际测得和合理假设的数据,从定量的计算定性地推断出在炉腹内确应有流态化床的存在。它的存在并不破坏位于其上的炉身内起换热作用的缓慢移动床。如果这个说法成立,则对于炉形的设计就有了比以前一般所用的经验公式更为合理的设计计算用的判据。计算结果大体上跟经验设计的相吻合。因此出现了足以阐明炉形的新的论据。此外,对于高炉利用系数的操作上限也可以从而获得计算的依据。凡此,都足以使高炉局部流态化的理论得以应用于高炉的实际设计。
Based on the hydrodynamic calculation of localized fluidized bed in high temperature fixed bed, the local fluidization of the material in the blast furnace bosh was investigated. Through the mathematical model, with the actual measured and reasonable hypothesis data, we can qualitatively infer from the quantitative calculation that there should be fluidized bed in the bosh. Its presence does not destroy the slow-moving bed in the shaft of the shaft above which the heat is transferred. If this statement holds, then the furnace design has more reasonable design and calculation criteria than previously used empirical formulas. The calculation results generally agree with the empirical design. Therefore, a new argument emerged that could explain the furnace shape. In addition, the operating ceiling for blast furnace utilization factor can also be calculated basis. All this is enough to make the theory of local fluidization of the blast furnace to be applied to the actual design of the blast furnace.
