摘要
碳酸盐是水泥生料配制的主要组份,是预热预分解技术的主要研究对象。众所周知石灰石的粒度是影响热解速率的主要因素,但缺乏这方面的基础工作的仔细研究。本文利用热天平对不同粒度范围的单级石灰石在离散态进行动态热重试验,观察其热解行为,利用实验求得的动力学参数寻找出计算水泥生料热解时的分解率和分解时间的解析式。
: The carbonate, a major component in the cement raw meal, is the subject of preheating and precalcining technology. It is well known that the particle size poses the main impact on the decarbonation rate. However the study in this respect is quite limited. The dynamic thermal weight test of the single stage limestone at different par-ticle sizes in discrete status was made with the aid of the thermal balance. The decarbonation behavior was observed and the dynamic parameters worked out from the test. The analytic formula about the raw meal decarbonation rate and time was found out.
