Discussion on the scenarios in which atmospheric pressure storage tank fire sprinklers are used
Thread Content
The main uncertainty lies in the timing of using fire sprinklers, especially for oils with a density lower than that of water (which is basically the case for all oils). Is the fire sprinkler system used only to cool down the tanks adjacent to the tank on fire when there is no flow of fire on the ground? ?
A fire sprinkler system is a firefighting device used for extinguishing fires and cooling down, capable of quickly spraying water or other extinguishing agents in the event of a fire. Fire sprinklers for atmospheric pressure storage tanks are mainly suitable for the following situations: 1. When the storage tank is on fire but there is no spreading flame on the ground: When there is no obvious spread of fire on the ground, the fire sprinklers can cool the surface of the burning tank by spraying water, thereby creating a protective layer that prevents the gassing of the burning material and the rupture of the container. 2. Cooling of adjacent tanks to a burning tank: When a fire spreads to neighboring tanks, fire sprinklers can cool the surfaces of those tanks by spraying water on them, thereby reducing the spread of the fire and preventing the adjacent tanks from catching fire. The use of fire sprinkler systems is subject to certain limitations for oils with a density lower than that of water. Oil with a density lower than that of water will float on the surface of water and cannot be completely covered by it. Under such circumstances, the fire sprinklers can only reduce the temperature by cooling the surface of the tank on fire, and are unable to effectively spray water onto the source of the oil fire. Therefore, when dealing with oil fires whose density is less than that of water, in addition to the fire suppression sprinklers in atmospheric-pressure tanks, other extinguishing methods such as foam firefighting and dry powder firefighting also need to be considered. Specifically, the appropriate fire extinguishing method should be selected based on the actual circumstances, and the operation should be carried out in accordance with relevant fire extinguishing guidelines or the advice of professionals. .
