International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 A reliable combustion monitoring system is essential to satisfy global carbon neutrality trends. As the concentrations of emissions and flame stability are associated with the air–fuel ratio, the equivalence ratio should be continuously evaluated. In this study, a deep neural network‐ (DNN‐) based regression model is proposed to predict the equivalence
