摘要

运用流体模拟软件Fluent和Matlab分别对碳素煅烧回转窑内气体空间和物料料层内的传热过程进行了研究，预测了窑内烟气、窑内壁和料层的温度分布。结果表明，窑内的高温区域主要集中在挥发分大量燃烧的区段上;二、三次冷空气的引入均会使窑内烟气温度明显下降，但对料层温度影响不显著。将窑外壁的计算结果与其实际测试结果进行了比较，两者吻合较好，说明该模拟方法的适用性，从而为碳素回转窑的优化设计和经济运行提供了指导和依据。

Abstract

Numerical simulations are conducted on the gas and solid spaces of the carbon rotary kiln using Fluent and Matlab.The temperature distributions for the gas

inner wall and solid in the kiln are predicted.The results show that the high temperature region in the kiln is in the zone where the volatiles burn massively.The injection of secondary or tertiary air causes obvious drop of gas temperature

but there is no obvious change of solid temperature.The predicted results of outer kiln wall temperature agree well with measurements.This model can be used to guide the optimum design and economic operation of carbon rotary kilns.
