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. Compared to covered stoves, top-uncovered stove exhibited 5.5% and 12.4% higher temperatures at the inner and outer covers, respectively, along with a 35% increase in heat flux. Comprehensive analysis revealed an approximately 20% enhancement in overall flame intensity. The experimental results show that top-uncovered gas stoves exhibit higher flame intensity, greater combustion efficiency, and overall higher stove efficiency. In contrast, covered gas stoves feature a more controllable and stable flame with a gentler temperature rise. This study underscores the importance of optimizing gas stove designs to enhance combustion efficiency and reduce emissions, contributing to the transition from fossil fuels to renewable energy sources and promoting sustainable development.
