介绍了一种基于流化床的生物质热解装置，其特点是用两个螺旋喂料机喂入原料，喷洒生物油冷却热热解蒸汽。实验结果表明，所开发的热解装置可以将生物质转化为生物油，并且所有生物质都有一个获得最大生物油产量的最佳温度。例如，锯末、稻壳、玉米秆和棉秆的生物油产量为在最佳热解温度下分别为63%、53%、57%和56%。分析表明，生物油的热值约为17 MJ/kg，生物油是水和含氧化合物的混合物，几乎包括所有化学类别。研究还表明，生物质干燥可有效降低生物油中的水分，存放半年的生物油仍可用作燃料油。
This paper introduces a kind of biomass pyrolysis set based on fluidized-bed,which has such characteristics as feeding feedstock with two screw feeders and cooling hot pyrolysis steam with spraying of bio-oil.Experimental result shows that the developed pyrolysis set is available to convert biomass into bio-oil and all biomass have an optimal temperature for maximum bio-oil yields.For instance,bio-oil yields of sawdust,rice husk,corn stalk and cotton stalk are 63%,53%,57% and 56% respectively at optimal pyrolysis temperature.The analysis indicates that the calorific value of bio-oil is about 17 MJ/kg and bio-oil is a mixture of water and oxygenic compounds including almost all chemical categories. The research also shows that drying biomass can effectively reduce the moisture in bio-oil,and the bio-oil stored for half a year still can be used as fuel oil.
