In this paper, numerical calculations are conducted to reveal the effects of H<sub>2</sub> enrichment and inlet velocity on flame behavior and combustion stability in an array micromix combustor. The results demonstrate that the combustor provides flexible combustion performance even under near-stoichiometric conditions, efficiently utilizing a wide range of fuels, including pure methane (CH<sub>4</sub>) and pure H<sub>2</sub>.

Blow-out of the H<sub>2</sub>-enriched array flame starts at the outermost nozzle, and this behavior occurs under all inlet velocity conditions from 20 to 120 m/s.

The results indicate that higher H<sub>2</sub> enrichment expands the blow-out limit range. Two inflection points emerge in the blow-out limit curve during the transition from CH<sub>4</sub> to H<sub>2</sub>. Additionally, increasing inlet velocity shifts the blow-out limit to higher equivalence ratios. However, this trend weakens as H<sub>2</sub> enrichment exceeds 80 %.

Within the framework of process intensification, enzymes and ultrasound can be combined within a sole process to increase isolation yield and reduce the usage of disposable chemical substances.
