摘要
通过建立新型干法水泥回转窑烧成带温度计算的数学模型,计算出两种不同水泥窑型的烧成带温度,分析了两种不同窑型的温度分布,进而提出熟料分段烧成的理想化模型。研究发现:短窑在过渡带具有普通窑型约8倍的温度梯度,但是在烧成带两者几乎没有温度变化,而分段烧成依然有15℃的升温,因此分段烧成具有良好的熟料反应温度环境,有利于熟料质量的提高。
By establishing the calculation of the mathematical model of NSP cement rotary kiln burning zone temperature （ BZT）, this paper computed two types of different cement kiln BZT, analyzed two types of different kiln temperature distribution, then put forward the idealized burn clinker piecewise model. The study shows that short kiln in transitional zone has ordinary kiln type temperature gradient approximately 8 times, but in the burning zone both almost have no temperature change and subsection firing still have 15℃ heats up. Therefore subsection firing a has good clinker reaction temperature environment, which is beneficial to improving the quality of clinker.
