Thermogravimetric analysis revealed that the primary degradation range of Zb was between 144–432 °C. Under the same heating rate, the N 2 /O 2 atmosphere was more favorable for the Zb combustion than was the CO 2 /O 2 atmosphere. The emissions of functional groups in both atmospheres remained similar and mostly occurred between 150 and 550 °C. Based on the multi-objective optimization of the best-fit neural networks, the maximum energetic performance and minimum gas emissions consistently occurred in the range of 575-1000 ℃ in the CO 2 /O 2 atmosphere. The propensity for slagging and scaling was significantly higher in the N 2 /O 2 atmosphere than in the CO 2 /O 2 atmosphere. The Zb ash exhibited higher alkalinity due to the presence of alkali metals, a lower melting temperature, and other characteristics associated with slagging. The combustion in both atmospheres followed a stochastic nucleation mechanism, suggesting high reactivity of the reaction system and positive and favorable progression of the reaction. This study provides valuable insights into the operationally optimal combustion dynamics of Zb, shedding light on how to best control and valorize its gas-to-ash byproducts. biomass incineration thermogravimetric analysis reaction mechanisms slagging kinetics Full Text Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
