摘　　要：在明确了生物质燃料特点的基础上,对生物质中碱金属元素的来源和析出迁移规律进行了概述。归纳出碱金属引起的腐蚀、聚团和沉积问题,并分析了引起这些问题的影响因素。指出解决生物质碱金属问题的四种常用方法,并总结了碱金属研究过程中存在的问题。Based on the characteristics of biomass fuel, this article summarizes the sources of alkali metals in biomass and the elutriation and migration. Three main problems including corrosion, coherency and sedimentation are concluded from a number of facts, and this paper analyzes many influencing factors for the matters. Four common methods, used to solve the matters caused by alkali metals in biomass combustion, are analyzed in this paper , and weak points in process of studying alkali metals are summarized.
