摘要
本文实验研究了在一种专门设计的具有多孔惰性介质燃烧器中预混火焰的燃烧特性.初步结果已经表明,在多孔介质中,热辐射对其火焰结构和燃烧速度有较大影响.燃烧速率比无惰性介质时提高了若干倍,最大火焰温度比普通的绝热预混火焰温度也高许多,火焰稳定性亦明显增强.
An experimental study was carried out by using a specially-desinged burner with a premixed flame burning withina porous inert medium. The preliminarv results have clarified thenoticeable effect of radiation in the inert medium on flamestructure and burning velocitv. The burning rate was remarkablyincreased by several times and the maximum flame temperaturewas even higher than that of a premixed adiabatic flame. Theflame stability was also enhanced.
