热载体与生物质粉混合物的特性分析与实验研究

Mixture of Heat-carrier and Biomass Powder

为确定快速热解反应器的设计参数,必须对热载体与生物质粉混合物的堆密度和滑动摩擦系数进行研究。为此,以石英砂和木粉为研究对象,对其不同质量比的混合物进行了实验研究,并对实验结果进行了分析。实验表明:热载体与生物质粉质量比在1:3～25:1之间时,混合物堆密度、滑动摩擦系数与热载体质量份数、热载体理论体积系数存在一定的线性关系。这些数据为热解液化工业示范装置的设计提供了依据。

In order to determine the design variable of Flash Pyrolysis reactor, we should study on the bulk density and friction coefficient about the mixture of heat-carrier and biomass powder. This article takes quartz sand and wood-flour as research object, and does research to the mixture which has different quality ratio and carries on the analysis to the experimental result, The experiment shows that： when the quality compares of heat-carrier and biomass powder from 1：3 to 25：1, there are certain linearity relations between bulk density and the quality number of heat-carrier, the sliding friction coefficient and the theory volume coefficient of heat-carrier. These data has provided the basis for industry demonstration of the pyrolytic liquefaction.
