Fire Fighting of Wind Extinguisher with CO2 Gas Assisted
The fire fighting equipments used for fight forest and grassland fire of China are mainly small two-stroke gasoline-powered portable wind fire-extinguishers owing to these areas are located in the more remote and inaccessible, where generally stay away from water. The main drawback of the wind fire-extinguisher is that it would lower the efficiency of power attributed to overheating of the two-stroke gasoline engine in the long process of firefighting, which will lead to decline the output speed and volumetric flow of fire extinguishing wind drived by the turbine when fire ambient temperature is high in the spring and summer. If this situation occurs, it will reduce efficiency of its fire fighting, what is more the adverse effects of wind to help the fire rather than put out the fire because the output of the extinguishing wind speed and volumetric flow is too small. In order to avoid the occurrence of such adverse effects and improve the extinguishing effect of fire extinguishers in the long process of firefighting, a program which use CO2 coordinate with wind fire-extinguisher to put out a fire was proposed in this paper, and the structure, characteristics of operation and precautions of the CO2 fire-extinguisher were described detailly.
