Bamboo wastes were naturally stacked for 1 month and were uniformly mixed with Chinese fir. Briquettes were manufactured by a briquette extruder at different process temperatures and mixing ratios. The physical, mechanical, pyrolysis, and combustion characteristics of briquettes were determined. The results showed that the mixing ratios and process temperature had a significant impact on the fuel properties of briquettes. The optimum briquettes were manufactured by 70% bamboo/30% Chinese fir blends at a process temperature of 520 °C. The fuel properties of optimum briquettes met the standard requirement of LY/T 2552-2015 and GB/T 28669-2012. The lower heating rate at the primary pyrolysis stage increased the yield of charcoal during the carbonization process of briquettes. The combustion process of briquettes added a char combustion stage, compared with the pyrolysis process. There were no synergistic interactions of bamboo and Chinese fir during pyrolysis and combustion process. The results of this research are helpful to develop large-scale production of bamboo briquettes or charcoal.

自然堆放竹/杉木混合物制成的煤饼的燃料特性

将竹废料自然堆放1个月,然后与杉木均匀混合。团块通过团块挤出机在不同的工艺温度和混合比例下生产。确定了团块的物理,机械,热解和燃烧特性。结果表明,混合比和工艺温度对煤饼的燃料性能具有显着影响。最佳煤球是由70%的竹子/ 30%的杉木混合物在520°C的温度下制造的。最佳型煤的燃料性能符合LY / T 2552-2015和GB / T 28669-2012的标准要求。在煤球的碳化过程中,初级热解阶段较低的加热速率提高了木炭的收率。型煤的燃烧过程增加了一个炭燃烧阶段,与热解过程相比。竹和杉木在热解和燃烧过程中没有协同作用。这项研究的结果有助于发展大规模生产竹炭或木炭。
