摘要
煤泥是煤炭洗选加工中的废弃物，但仍含有相当量的热值，将煤泥通过管道远距离输送到锅炉燃烧发电是目前解决煤泥利用的最佳途径．煤泥作为高浓度黏稠物料进行管道远距离输送存在很多困难，其流变特性研究是管道输送的重要理论基础．本文从上述角度出发，介绍了煤泥的物理特性和实验仪器，通过对质量分数为55％～75％的煤泥进行系统地测试，绘制了流变曲线和黏度曲线，确定了煤泥的流变类型，得出了煤泥的流变方程．通过对煤泥的流变特性研究，为煤泥管道输送设备的优化设计提供了基本参数．
Slime, waste from cleaning and processing coal, has enough application value as the low calorific fuel because of its largish quantity of heat. Nowadays, the best approach to utilize slime is to transport them into boiler for combustion and power generation through the long-dlstance pipeline. As high density and viscosity material, slime is difficult to be transported through the pipeline. Research on the theological characteristics of the slime is very important for studying pipeline transportation. The physical characteristics of slime and the instruments applied in experiment were introduced. According to the rheological characteristics curves and viscidity curves obtained through systematic test on slime （with a mass concentration of 55%-75% ）, its rheologic type was ascertained, the equations were educed. The study of the rheological characteristics of slime can offer the basic parameters for optimization design of slime pipeline transportation equipment.
