Box 5, 305-343, Taejeon, Korea aut Inhibition effectiveness of dry chemical in methane/air flames [Elektronische Daten] [Hyung-Taek Kim] Inhibition effectiveness of dry chemical powders has been examined by detecting the temperature changes in the quenched flat-flame burner. A special particle delivery system was constructed to supply reliable particle concentration to a quenched flat flame. Particle evaporation phenomena in the flat flame environment was investigated by utilizing laser attenuation method which could determine the fraction of particle disappearance in the flame. The result from the flat flame inhibition experiments have clearly demonstrated that the ranking of effectiveness among KHCO3, NaHCO3, and NaCl reverses over the 1200-2000 K temperature range as flame suppressants. The results also showed that dry chemicals are effective inhibitor in the high temperature condition such as in the gaseous flame but not effective one in the coal flame of low temperature. It is concluded that, of all the experiment-specific flame properties, the maximum flame temperature at which the inhibitor evaluation is conducted, was a major parameter to determine the flame inhibition effectiveness in this work.
