A Study on Reduction of Soot Particle in a Flame by Microwave Heating

尝试用微波辐射降低火焰中的碳烟浓度。利用激光诊断仪测量了火焰中的碳烟体积浓度和碳烟颗粒直径，并讨论了微波辐射对碳烟形成过程的影响。结果表明，最大碳烟体积浓度降低了20%左右。另一方面，碳烟颗粒的直径受微波辐射的影响较小。

The reduction of soot concentration in flames is tried by the irradiation of microwave. The soot volume concentration and the diameter of soot particles in the flame are measured by the laser diagnostics, and the effects of irradiation of microwave on the soot formation process are discussed. As results, it is observed that the about 20% reduction of soot volume concentration in maximum is occurred. On the other hand, the diameter of soot particle is little affected by the irradiation of microwave.
