摘要
分析了陶瓷板红外线燃气灶热效率比大气式燃气灶高的原因:具有陶瓷板辐射体,辐射效率高;燃气燃烧需要的过剩空气系数小,致使理论燃烧温度高,增强了换热,减少了排烟损失;锅支架高度小,有利于增加换热量和减小向周围的辐射散热损失。
This paper analyzed the reason why the thermal efficiency of an infrared gas range with ceramic plaque is higher than that of an atmospheric gas range. An infrared gas range with ceramic plaque has a radiant ceramic plaque which raises its radiant efficiency, and needs fewer excessive air that results in higher theory combustion temperature and fewer venting heat loss, and its shorter panrest increases the heat exchange and reduces the thermal radiation to surroundings.
