熱風炉におけるスタッガード・パラレル操業の理論解析  [in Japanese] Theoretical Analysis of Staggerd-Parallel Operation in Hot-Blast Stoves  [in Japanese]

Staggerd-parallel operation in hot-blast stove is theoretically investigated on the basis of both numerical and analytical methods. The effects of non-dimensional factors in the mathematical model on the longitudinal distribution of brick temperature and on the fractional distribution of blast to each stove have been evaluated by means of the numerical computations. By applying the analogues method with the method used in the previous paper on the analysis of single blowing operation to a staggerd-parallel operation, the approximate solution and the necessary conditions relevant to a balanced cycle have been obtained. Although the analysis on a staggerd-parallel operation becomes rather difficult since the flow rate of air varies considerably during the cooling period, good agreements between the results obtained from the approximate solution and those from the numerical computation have been found. Several diagrams to be available for the rational stove design are drawn up on the basis of approximate solution mentioned above.
