增压流化床煤水混合物流变特性影响因素分析

Analyses of Rheological Properties of Coal Water Mixture for Pressurized Fluidized Bed Combustion

从悬浮体流变机理和煤水混合物中煤粉颗粒的堆积形态分析入手 ,提出了关于煤水混合物悬浮体的流变机理假设 ,并在此基础上讨论了诸因素对煤水混合物流变特性的影响和煤水混合物配制的最佳颗粒度配比。

In this paper beginning with the rheological mechanism of suspended substances and analyzing the piling pattern of a coal particles of coal water mixture,a rheological mechanism assumption of coal water mixture is proposed.On the basis of the assumption,the effects of various factors on the rheological properties of the coal water mixture and the optimum particle distribution of coal water mixture preparation are discussed.
