Abstract This study systematically investigated the effects of different gas stove structures on flame combustion characteristics using spectral diagnostic techniques, aiming to provide optimized design guidelines for clean energy applications. To explore the combustion behaviors of various gas stove structures, UV cameras, high-speed cameras, and K-type thermocouples were employed to measure parameters such as flame OH radicals (OH*), flame morphology, pulsation frequency, flame temperature, and heat flux. The results demonstrate that flame stability was achieved at an inner/outer cover flow rate ratio of 0.5/4.0 L/min, beyond which further flow rate increases led to reduced combustion efficiency.… More >
