甘蔗渣是制糖生产的副产物，是一种可再生的生物质燃料。甘蔗糖厂压榨机排出的蔗渣含水分一般在48％左右（低位热值约8100kJ／蝇），而干燥后蔗渣含水分低于40％（低位热值高于9738kJ／kg），作为锅炉燃料热效率提高20％以上。本文介绍利用锅炉烟道气干燥蔗渣技术及生产实践经验，探讨滚筒式蔗渣干燥器在使用过程中存在的一些问题以及改进措施。%Bagasse, a by-product of sugar production, is a renewable biomass fuel. The moisture content of bagasse is commonly about 48% produced by the squeezer of cane sugar factory, and the corresponding low calorific value is about 8100 kJ/kg, dried bagasse moisture content is below 40% （low calorific value higher than 9738 kJ/kg）, increased by more than 20% thermal efficiency as boiler fuel. In this research, the production technology and practice experience of drying bagasse by boiler flue gas was introduced, and a few problems existed during the using of bagasse rotary-drum drier and the relevant improvement measures were also discussed.
