摘　　要：生物质能的应用形式多种多样,将其转化成生物质油再加以利用便是其中一种。在此,选用流化床作为转化装置,利用生产过程中产生的不凝气作为生物质颗粒的操作气体和热载体。对于燃烧热源的设计,参考了火管锅炉炉膛的设计方法,热烟气与不凝气换热部分的设计参照了管壳式换热器的设计方法,而流化热裂解部分的设计与传统流化床的相似,但选用的物料粒径会影响到流化反应效果和反应器设计尺寸,因此对物料粒径的选取与反应器数量分配和流化床的床径、床高之间的关系进行了探讨。Converting biomass into bio-oil to use is one of the applications of biomass energy form.The fluidized bed was selected as conversion device and the non-condensable gas was adopted as the operating particles and heat carrier.The combustion furnace was designed refer to the fire tube boiler.Furthermore,the method of tube and shell heat exchanger was used to design the device which transfers heat between hot flue gas and non-condensable gas.In addition,the design of the fluidized pyrolysis device is similar to the conventional fluidized bed,but the chosen material particle size would affect the fluidization reaction effect and reactor design size.So the relationship between the selection of particle material size,reactors＇ distribution and fluidized bed＇ s diameter and height were discussed.
