本文根据串联和并联“热流阻力”的概念,提出了综合解决窑炉传热问题的“热流线路分析法”,并分别解决了旋窑中各项主要“热阻力”的计算公式。本文中建议把△（T~n）作为辐射传热的推动力。在讨论衬砖周期蓄热过程中,指出了适用於温度及热流的平均值的“阻抗”公式,与适用於“方均根值”的交流阻抗公式不同,并提供了一个有理论根据的近似公式。对物料粒子间的传热机理亦作了初步分析。 According to the concept of “heat flow resistance” in series and in parallel, this paper proposed a “heat flow route analysis method” to comprehensively solve the problem of heat transfer in kilns and solved the calculation formulas of the main “thermal resistances” in rotary kilns respectively. In this paper, it is suggested that △ (T ~ n) be the driving force of radiation heat transfer. In discussing the thermal history of the lined brick cycle, the “impedance” formula for the average of temperature and heat flow is indicated, which is different from the AC impedance formula for “root mean square” value and provides a theoretical approximation formula. On the heat transfer mechanism between particles also made a preliminary analysis.
