摘　　要：中国不同地区气候不同,温湿度差异较大,生物质颗粒燃料在储藏过程中,会引起颗粒燃料的特性发生变化,从而对燃料的应用产生影响。针对玉米秸秆颗粒和木质颗粒两种燃料,采用密封和露天2种储藏形式,利用高低温湿热试验箱模拟不同温湿度条件,开展储藏试验。结果表明,生物质颗粒燃料在储藏过程中,影响颗粒燃料全水分的主要因素是温度、湿度和储藏方式;湿度大于70%,玉米秸秆颗粒燃料会出现长毛、发霉现象;木质颗粒燃料在高温、高湿条件时,会出现裂缝及发霉现象。In China,there are great difference in temperature and humidity in different regions.During the storage time,the characteristic of biomass pellet fuel will change,so the application of the fuel will also change.The corn stalks and wood pellet were tested with different storage method,temperature and humidity.The results showed that during the storage time,the temperature,humidity and storage method were the main factors which affected the total moisture of pellet fuel.When the humidity was larger than 70%,the corn stalks will appear mildew.The wood pellet will crack and mildew under the condition of high temperature and humidity.
