Foam System Fire Protection

The foam maker is normally installed in the line of a semi fixed or fixed foam fire protection system.
Foam system fire protection. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. Foam makers are air aspirating foam discharge devices used primarily for the protection of the seal area of open top floating roof storage tanks and dike areas around storage tanks. From our halar coated control valves our three ul listed proportioning methods and our wide range of discharge devices that includes the viking grate nozzle you. Other components of fire retardant foams are.
Additional applications include protection of spill hazards. The size of the facility the hazard area to be protected the authority having jurisdiction and the assets being protected all play a big role in deciding what fire suppression system to use. Firefighting foam is an integral part of tank fire protection system. Fluor protein foams are best for hydrocarbon risks and alcohol resistant aqueous film forming foam ar afff for water miscible risks or polar solvent.
Foam water spray systems can be used for a combination of class a and class b hazards. The foam concentration must suit different tank content and application systems. Maurice stewart in surface production operations 2016. Firefighting foam is a foam used for fire suppression its role is to cool the fire and to coat the fuel preventing its contact with oxygen resulting in suppression of the combustion fire fighting foam was invented by the russian engineer and chemist aleksandr loran in 1902.
For foam systems foam must be delivered to the fire efficiently and in a controlled and directed manner. Foam water systems generally work by allowing foam concentrate to mix with water flowing into the piping system. The surfactants used must produce foam in concentration of less than 1. Viking foam products viking s foam water based systems are fully integrated ensuring the operational compatibility of every component from foam concentrate to discharge devices.
Our fire protection design engineers have experience over a vast range of installations and will analyse your facility the fire risk and consider likely scenarios. 9 21 6 fire protection 9 21 6 1 foam protection systems. Foam fire extinguishing system. Every facility has different needs when it comes to fire suppression.
Foam in powder form is mixed with water and forms foam suds. They are mostly applicable to the protection of two dimensional flammable liquid hazards. A foam system is usually specified for cone roof tanks. They will design a system configuration to effectively combat fire help.
This is done in a foam mixing unit located inside a foam pump house.
