Fixed Aerosol Fire Extinguishing Systems For Warehouse Fire Protection

Why warehouse need fire protection?

Warehouse fire protection is difficult. Warehouses are constantly evolving, and changing in size and commodity.To keep warehouses safe from fire, owners need to work closely with fire protection contractors. If the warehouse is storing different products/materials, or needs to expand in size, a fire protection contractor should be consulted to make sure that it still meets code.

Fireless 50 is used to protect 25~50m³,depending on the protected objects. For example, if you want to protect 50 meters cubed space, it is recommended to increase the number of fire extinguishers if the thing being protected is flammable. If the object being protected is not flammable, the number of fire extinguishers can be reduced.

Technical parameters for Aerosol Fire Extinguishing System

Aerosol extinguishing mechanism

1. mechanism of heat absorption and cooling to extinguish fire .

Metal salt particles absorb a large amount of heat under high temperature, thermal fusion, gasification and other physical heat absorption process, flame temperature is reduced, and then radiation to the combustor combustion surface for gasification of combustible molecules and gasification of combustible molecules pyrolysis into free radicals of heat will be reduced, combustion reaction rate to a certain extent.

B. chemical suppression mechanism.

• Chemical inhibition in gas phase: under the action of heat, the dissociated gasified metal ions or the cations losing electrons in the fire-extinguishing aerosol can have affinity reaction with the active groups in the combustion, consume a large number of active groups repeatedly and reduce the combustion free radicals.
• Solid phase chemical inhibition: the particle size of fire-fighting aerosol is very small (10-9 ~ 10-6m), with a large surface area and surface energy, which can absorb the active groups in combustion and produce chemical effects, consume a large number of active groups and reduce combustion free radicals.
• Reducing oxygen concentration: N2 and CO2 in fire-extinguishing aerosol can reduce oxygen concentration in combustion, but the rate is slow, and the fire-extinguishing effect is far less than endothermic cooling and chemical inhibition.
