论文摘要
混合温度控制（MTC）燃烧是一个新颖的概念，与没有已知妥协的V形火焰相比，NOX发射的降低50％。火焰稳定至等效比为0.57，随着接近瘦小的可燃性极限，其随后是井喷。瘦燃烧还意味着降低火焰繁殖速度，是保持火焰升起并促进均匀混合物形成的另一个关键特征。据观察，在更苗条的条件下，分布式燃烧更容易实现。与无火的燃烧或废气再循环技术（例如轻度燃烧）不同，氧化剂可以是环境空气，可以在实际应用中实现强大的实现。分布式火焰的特征是低火光和噪声。它的声谱主要包含与几何相关的组件。因此，假设该概念比V形火焰的热声不稳定性的趋势较低。
Mixture Temperature-Controlled (MTC) combustion is a novel concept, offering 50% reduction in NOx emission compared to V-shaped flames without a known compromise. The flame was stable up to an equivalence ratio of 0.57, which was followed by blowout as the lean flammability limit was approached. Lean combustion also means reduced flame propagation speed, being another key feature to keep the flame lifted and facilitating homogeneous mixture formation. It was observed that distributed combustion was easier to achieve under leaner conditions. Unlike flameless combustion or exhaust gas recirculation techniques, such as MILD combustion, the oxidizer can be ambient air, offering robust realization in practical applications. The distributed flame is characterized by low flame luminosity and noise. Its acoustic spectrum contains geometry-related components principally. Hence, it is hypothesized that this concept also has a lower tendency to thermoacoustic instabilities than V-shaped flames.
