Mixture temperature-controlled combustion: A revolutionary concept for ultra-low NOX emission

Mixture Temperature-Controlled (MTC) combustion is a novel concept, offering 50% reduction in NOX emission compared to V-shaped flames without known compromise. The essence of this concept the central cold air injection, which also atomizing medium plain-jet airblast atomizer presently delay fuel–air mixture ignition. Hence, flame root not anchored fuel nozzle or burner lip, facilitating distributed through homogeneous temperature field, ultimately leading reduced emission. was stable up an equivalence ratio 0.57, followed by blowout as lean flammability limit approached. Lean means propagation speed, being another key feature keep lifted and formation. It observed that easier achieve under leaner conditions. Unlike flameless exhaust gas recirculation techniques, such MILD combustion, oxidizer can be ambient air, robust realization practical applications. characterized low luminosity noise. Its acoustic spectrum contains geometry-related components principally. it hypothesized has lower tendency thermoacoustic instabilities than flames.
