摘要:
为了分析2种灭火剂扑灭火旋风效果，采用实验室自制装置生成稳定的火旋风火焰，喷射CO2或ABC干粉灭火剂，获取火焰温度场及光电信号数据。研究结果表明：在CO2灭火剂或ABC干粉灭火剂作用下火旋风火焰温度场呈“下凹”型指数衰减；受灭火剂喷射位置影响，火焰根部、中部及顶端不同区域的灭火剂影响系数不同；基于火焰降温速率和光信号变化，相较于CO2灭火剂，对火焰起抑制作用的ABC干粉灭火剂降温效率更高、扑灭效果更好。
Abstract:
In order to analyze the effect of two kinds of fire extinguishing agents on extinguishing the fire whirlwind, the stable fire whirlwind flame was generated by using the selfdeveloped device in the laboratory, and the temperature field and photoelectric signal data of flame after spraying the CO2 fire extinguishing agent or ABC dry powder fire extinguishing agent were obtained. The results showed that under the effect of CO2 fire extinguishing agent or ABC dry powder fire extinguishing agent, the temperature field of fire whirlwind flame presented an exponential decay of “down concave” type. Affected by the spraying positions of fire extinguishing agent, the influence coefficients of the fire extinguishing agent at the root, middle and top of the flame were different. Based on the change of temperature reduction rate and optical signals of flame, the ABC dry powder fire extinguishing agent with the inhibitory effect on the flame had the higher cooling efficiency and better extinguishing effect compared with the CO2 fire extinguishing agent.
