摘　　要：生物质燃料在循环流化床(CFB)中的燃烧正在得到进一步的应用和开发。在燃煤CFB锅炉模型化设计的基础上,针对生物质燃料的特点和现有的CFB研究成果,进行了生物质燃料CFB锅炉的建模、程序设计和锅炉设计,同时对一些新的模型内容进行了介绍。模型的计算结果同已报道的试验结果较为吻合。Modern techniques for biomass energy utilization include in general direct combustion, gasification, and pyrolysis. Since the end of the 1980s, the circulating fluidized bed has found application in burning of biomass. Some companies and research institutes in China are currently starting to develop the biomass-fuelled circulating fluidized bed boiler. In this presentation, a modeling approach for the biomass-fuelled circulating fluidized bed boiler (BCFBB) was described, which was established on the basis of the existing model for coal-fuelled circulating fluidized bed boilers, acquired results for CFB investigations, and the characteristics of biomass. Calculations for a 35 t/h BCFBB were carried out using the model in order to verify it. The acquired results agree fairly well with the experimental data reported.
