Top temperature control method for vertical co-firing lime kiln
The embodiment of the invention provides a top temperature control method for a vertical co-firing lime kiln. The top temperature control method comprises the following steps: constructing a top temperature control function by taking the kiln bottom air volume adjustment amount in a vertical co-firing lime kiln as an adjustment object; and adjusting the kiln bottom air volume according to change conditions, wherein the change conditions specifically comprise top temperature change and stone feeding amount change, wherein PID dynamic adjustment is performed based on temperature change and kilnconditions, dynamic adjustment of an air volume adjustment coefficient is performed according to the stone feeding amount change and the kiln conditions, and finally the kiln bottom air inlet volume is obtained through calculation so as to achieve fine control of the top temperature of the lime kiln. According to the method, the accuracy and the timeliness of lime kiln top temperature control canbe improved, the optimal control over the lime kiln top temperature is achieved, and the lime kiln calcining area is stabilized, so that the lime kiln calcining quality is improved, and coke consumption is reduced.
本申请实施例提出了用于竖式混烧石灰窑的顶温控制方法，包括以竖式混烧石灰窑中窑底风量调节量为调节对象构建顶温控制函数；根据变化情况对窑底风量进行调节。这里的变化情况具体包括顶温变化以及上石量变化，前者基于温度变化和窑况进行PID动态调整，后者则是根据上石量变化和窑况进行风量调节系数的动态调整，最终都是借助计算得到窑底进风量，对石灰窑顶温进行精细化控制。该方法可以提高石灰窑顶温控制的准确性和及时性，实现石灰窑顶温的优化控制，稳定石灰窑煅烧区，进而提高石灰窑煅烧质量，降低焦炭消耗。
