This study aimed to turn a better understanding of the combustion dynamics of ginger (Zb) residues into operationally optimal conditions. Thermogravimetric analysis revealed that the primary degradation range of Zb was between 144–432 °C. Under the same heating rate, the N2/O2 atmosphere was more favorable for the Zb combustion than was the CO2/O2 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 CO2/O2 atmosphere. The propensity for slagging and scaling was significantly higher in the N2/O2 atmosphere than in the CO2/O2 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.
