Abstract

Our goal was to explore the potential of bamboo as a solid biomass fuel through torrefaction and compare it with previous studies on unused forest biomass chips. The torrefaction process involved temperatures of 230–310 °C increased in 20 °C intervals, each lasting an hour. Significant differences in mass were evident between the 270 and 290 °C processing conditions during thermogravimetric analysis. Differential thermogravimetric analysis showed that both the initial and peak temperatures increased with higher processing temperatures. The mass yield ranged from 32.37 to 76.74%, and the calorific value varied from 19.50 MJ/kg to 28.68 MJ/kg. Compared to previous studies on the torrefaction of Liriodendron tulipifera and Pinus koraiensis, bamboo exhibited a relatively lower mass yield and calorific value; however, it was considered suitable compared to unused forest biomass wood chips. The optimal conditions for torrefaction were found to be 270 °C during processing.

通过高温分解确定作为固体生物燃料的竹屑的燃料特性

我们的目标是探索竹子作为固体生物质燃料的潜力，并将其与之前对未使用的森林生物质碎片的研究进行比较。高温分解过程的温度为 230-310 °C，每隔 20 °C升温一次，每次持续一小时。在热重分析过程中，270 ℃ 和 290 ℃ 处理条件下的质量差异明显。差异热重分析表明，初始温度和峰值温度都随着加工温度的升高而升高。质量产率从 32.37% 到 76.74% 不等，热值从 19.50 兆焦/千克到 28.68 兆焦/千克不等。与之前关于郁金香和柯来松的研究相比，竹子的质量产率和热值相对较低；然而，与未使用的森林生物质木片相比，竹子被认为是合适的。研究发现，在加工过程中，270 ℃ 是最佳的热解条件。

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
