摘　　要：通过实验研究,得到一种超低热值煤气Ⅰ型辐射管烧嘴,该烧嘴可适用煤气最低热值达4 598 kJ/m3(1 100kcal/m3)。点火实验结果表明:烧嘴火焰检测信号随着煤气热值下降逐步减弱,随着空气消耗系数的增加而增强,随着供气流量的加大而增强。实验烧嘴除可适用低热值煤气外,同时还具有热效率高、加热温度均匀性好和有害气体排放低等优点。A kind of I -type radiant tube burner for low heat value gas is successfully developed by experimental study, and the lowest Calorific Value of gas suitable for the burner is up to 4 598 kJ/m^3. The results of burner ignition experiment show that the flame detecting signal gradually weakens with the decrease of gas calorific vaiue, and enhances with the increase of air excessive coefficient and gas flow. Besides having the advantage of using low heat value gas, the burner has many other advantages such as high heat efficiency, good temperature uniformity and low emission of NOx and CO.
