Experimental Study on Synergistic Fire Extinguishing between Different Potassium Additives in Water Mist
Zhe Dong, Shao-Kun Wei, and Lin-Shuang Zhao
Abstract—In order to study the synergistic fire extinguishing effect of potassium salt additives in water mist, the fire extinguishing experiments were carried out with the two of seven kinds of potassium salt additives (KNO3, CH3COOK, K2C2O4, KCl, K2CO3, K2SO4 and KHCO3) with the same mass fraction. The results show that the fire extinguishing time of K2C2O4 - K2SO4, K2CO3 - CH3COOK, K2CO3 - KCl, KNO3 - K2SO4, CH3COOK - K2SO4 is less than the fire extinguishing time of the single additive, which indicates that the chemical inhibiting effects of the additives are enhanced, and there is a synergistic fire extinguishing effect among the potassium additives combinations which are mentioned above. Finally, the mechanism of the synergistic fire extinguishing effect is conjectured as follows: under the activation of high-temperature steam in the flame zone, a kind of substance after melting or decomposing accelerates the generation rate of fire extinguishing active substances, thereby increasing the extinguishing efficiency.
