石灰石煅烧过程等效扩散系数的测量

Measurement of Equivalent Diffusivity During the Calcination of Limestone

对大颗粒石灰石煅烧过程中的测量等效扩散系数公式进行推导的基础上 ,通过测定其失重曲线和煅烧完成时间 ,获得了煅烧后产物层内的等效扩散系数。对多种石灰石进行了试验 ,发现在不烧结的情况下 。

Based on the derivation of the expression for the calculation of equivalent diffusivity during calcinations of large particles of limestone,the measured weight loss and calcination time,the equivalent diffusivity of porous layers of the product after calcination was obtained.Eight types of limestones were used in the tests,and the experimental results show that the equivalent diffusivity of different limestones were almost the same when sinter did not occur in calcinations.
