Abstract

This study investigates the viability of tea waste as a biomass feedstock for pellet production and its combustion characteristics. Tea waste, an abundant agricultural byproduct, presents a promising avenue for renewable energy generation if effectively utilized. The pellets derived from tea waste were subjected to detailed analysis focusing on their calorific values and carbon composition. The calorific value of tea waste pellets was determined to be approximately 18.5 MJ/kg, comparable to conventional wood pellets. Notably, these pellets exhibit a high carbon content of 45 %, indicating a significant fixed carbon fraction that necessitates tailored combustion strategies for optimal efficiency. This research underscores the potential of tea waste pellets as a sustainable biofuel, contingent upon the development and application of precise combustion methodologies. It underscores the critical importance of understanding the chemical properties of solid biofuels in optimizing their utilization for energy production.

生物质的价值化：茶叶废料颗粒和木质颗粒产生蒸汽及排放情况的比较分析

本研究调查了茶叶废弃物作为生物质原料生产颗粒的可行性及其燃烧特性。茶叶废弃物是一种丰富的农业副产品，如果得到有效利用，将为可再生能源的生产提供一个前景广阔的途径。对茶叶废弃物制成的颗粒进行了详细分析，重点关注其热值和碳成分。经测定，茶叶废弃物颗粒的热值约为 18.5 兆焦/千克，与传统木质颗粒相当。值得注意的是，这些颗粒的含碳量高达 45%，表明其中有大量固定碳，因此必须采取量身定制的燃烧策略才能达到最佳效率。这项研究强调了茶叶废料颗粒作为可持续生物燃料的潜力，但这取决于精确燃烧方法的开发和应用。它强调了了解固体生物燃料的化学性质对优化利用其生产能源至关重要。
