烤烟秸秆压块代煤在烟叶烘烤中的应用效果研究

摘要

In order to recycle the straw of flue-cured tobacco and find new fuel of flue curing which might substitute for coal,the straw was dried and crushed into blocks after tobacco leaves harvest for fuel of flue curing using the straw briquetting machine,and tests of flue curing replacing coal were carried out. The results showed that the flue curing curve of the straw briquetting was largely in line with that of coal,and it could satisfy the needs of flue curing,the grade qualities of tobacco leaves were equal to those by coal,and the straw briquetting consumption to coal was 1.64:1. The cost of flue curing reduced by 189 yuan/hm2. So it was possible to use straw briquetting instead of coal in tobacco flue curing,and also significant to reduce environmental pollution and develop circular economy of tobacco.%为了实现烤烟秸秆循环利用和寻找烟叶烘烤替代燃料，将烟叶采收后的秸秆晒干并粉碎，利用秸秆成型机压块制成烘烤燃料，进行了替代煤炭烘烤烟叶试验。结果表明：烤烟秸秆压块作燃料烘烤工艺曲线与煤炭基本吻合，可满足烟叶烘烤要求，烤后原烟等级质量与煤炭相当，秸秆压块消耗量与煤炭之比为1.64：1，可降低烘烤燃料成本约189元/hm2。因此，烤烟秸秆压块替代煤炭烘烤烟叶是可行的，对减少环境污染和促进烟叶循环经济发展也具有积极意义。
