摘　　要：在生物质的气化流程中,由于生物质粉末本身的理化特性,使得对于生物质的气力输送面临着许多的挑战。为降低输送成本,搭建了能够连续可靠运行的生物质粉末(锯末)气力输送实验台。研究不同流化风流量、载气风流量、罐压、背压下生物质原料气力输送特性,以及固相质量流量的相关变化规律。通过对前人所提出的气力输送模型进行研究,并得到了气力输送的固相质量流量多元回归公式,经与实验数据比对,具有良好的匹配性较好的预测效果。In the process of gasification with biomass, due to the property of pulverized biomass, pneumatic convey face so many challenging. In order to reduce transportation cost, an efficient pneumatic transport system has been designed for the continuous and smooth conveying of saw dust. The max flux of biomass was studied as the system parameter were varied, such as aerating gas, fluidizing gas, transfer gas and pressure drop. At the same time compared the models put for- ward by former researcher with the data obtained, result showed that the models have a good prediction effect.
