摘　　要：生物质成型颗粒燃料具有易储存、运输及使用方便、清洁环保、燃烧效率高等优点。本文通过实验得到八种生物质颗粒燃料的工业分析值,结合傅—张着火指标和缪岩燃烧特性指标分别计算出FZ和ZM值,得出装饰纸的着火温度最低,稻壳的着火温度最高。通过观察燃料燃烧后焚烧灰的形貌,指出在740～920℃温度范围内,生物质颗粒燃料燃烧后的灰颜色由黑逐渐变白,硬度由软逐渐变硬,甚至结焦渣。The biomass pellet fuel is easy to store and transport, convenient to use, clean and helpful to environmental protection, and of high combustion efficiency. The study obtained the industry analysis values of eight kinds of biomass pellet fuels by experiment. Combined with fire indicator of Fu Zhang and combustion characteristics indicator of Yan Niu, the study calculated the values of FZ and ZM and shows that the decorative paper has the minimum ignition temperature, while the rice husk has the highest ignition temperature. Finally, through the observation of the morphology of ash after the burning of fuel combustion, it is pointed out that with the increase of temperature from 740℃ to 920℃, gray color of pellet fuel became gradually from black to white and hardness gradually harden- ed, even coke residue.
