Utilizing biomass energy plays a pivotal role not only in mitigating greenhouse gas emissions but also in achieving carbon neutrality and environmental sustainability. The primary objective of this study was to quantify gas emissions, ash properties, and the bioenergy potential of the ginger residue (Zb) combustion in response to the air and oxygen-enriched atmospheres by using thermogravimetric analysis coupled with Fourier-transform infrared spectroscopy. The primary degradation of the Zb combustion occurred between 144 and 432 °C. Compared with the 79 % CO/21 % O atmosphere at the same heating rate, the 79 % N/21 % O atmosphere favored the Zb combustion. The combustion gas products were consistent in both atmospheres and predominantly occurred between 150 and 550 °C. The combustion process in both atmospheres adhered to the mechanism of random nucleation, signifying a highly reactive and favorable reaction system. The joint optimization based on an artificial neural network confirmed that the primary temperature for achieving maximum heat release and minimal gas emissions in both atmospheres varied between 575 and 1000 °C. Overall, Zb serves as an environmentally friendly and renewable resource for biomass energy production. Findings of this study can provide a basis for bioenergy production, pollution control, and optimizing efficiency in the industrial applications of the Zb combustion.

生姜残留物对 CO2/O2 和 N2/O2 气氛的燃烧机制、烟气排放和灰分特性


利用生物质能源不仅在减少温室气体排放方面发挥着关键作用，而且在实现碳中和和环境可持续性方面也发挥着关键作用。本研究的主要目的是通过热重分析与傅里叶变换红外光谱相结合，量化姜渣 (Zb) 燃烧对空气和富氧气氛的反应的气体排放、灰分特性和生物能源潜力。 Zb 燃烧的主要降解发生在 144 至 432 °C 之间。与相同升温速率下的79%CO/21%O气氛相比，79%N/21%O气氛更有利于Zb的燃烧。两种气氛中的燃烧气体产物是一致的，并且主要发生在 150 至 550 °C 之间。两种气氛中的燃烧过程都遵循随机成核机制，表明反应体系具有高反应性和有利的反应体系。基于人工神经网络的联合优化证实，在两种大气中实现最大放热和最小气体排放的主要温度在 575 至 1000 °C 之间变化。总体而言，Zb是一种用于生物质能源生产的环境友好型可再生资源。这项研究的结果可以为Zb燃烧工业应用中的生物能源生产、污染控制和优化效率提供基础。
