污泥热解气氨旋流火焰燃烧特性
摘要：摘要污泥热解气因难以被有效利用导致了大量的能源浪费,而其中所含的氢气、甲烷等可燃组分可有效提升氨燃料的燃烧性能。对污泥热解气掺氨旋流火焰的结构及燃烧特性进行分析,基于化学发光法,通过实验考察当量比、掺氨比对火焰结构的影响。结果表明,旋流燃烧火焰中的OH* 在化学当量条件（φ = 1.0）下辐射强度最大,CH* 在富燃条件（φ = 1.2）下辐射强度最大,OH* 可以对火焰稳定性进行更好地表征;污泥热解气/氨气混合燃料中,随着氨气比例增大,旋流火焰稳定性下降。
Abstract:：Sludge pyrolysis gas is difficult to effectively utilize, resulting in a large amount of energy waste, while the combustible components such as hydrogen and methane can effectively improve the combustion performance of ammonia fuel. This study analyzed the structure and combustion characteristics of the sludge pyrolysis gas-doped ammonia swirl flame. The effects of the equivalence ratio and ammonia doping ratio on the flame structure were studied through experiments based on the chemiluminescence method. The results indicated that OH* and CH* in swirling combustion flames exhibited the highest radiation intensity under chemical equivalent conditions (φ = 1.0) and fuel-rich conditions (φ = 1.2), respectively. OH* can better characterize flame stability. In the sludge pyrolysis gas/ammonia mixed fuel, the stability of the swirling flame decreases as the ammonia ratio increases.
