best storage tank fire extinguishment: superiority of simplicity
How can FoamFatale be so effective?
Storage tank fire extinguishment systems are made up of a complex chain of equipment. Proportioners, pumps, foam generators, foam concentrate, fire water, pipelines, foam dispensers, foam monitors – all sound very familiar to you, right? Limited performance, limited efficiency, limited workforce, limited electricity and water supply, limited reliability, vulnerability: unfortunately, these are all familiar in the storage tank firefighting industry. This contributes to the low success rate of systems and the safety risk.
FoamFatale does not use any of the above in its method.
Due to the limited speed of foam application, other storage tank firefighting methods can hardly extinguish massive tank fires. We have developed a new foam supply and introduction method to overcome this limitation to achieve colossal foam flow. This method is based on a well-known physical phenomenon: pressure. Pressure always works. Even in space…
First and foremost, two key elements of the FoamFatale storage tank fire suppression system:
1./ The different foam supply method: foam premix, stored under pressure. We can call it Self Expanding Foam (SEF®), Instant Foam (IF), or Pressurized Instant Foam (PI Foam) as well.
The planned foam quantity is always ready for extinguishing at any moment.
There is no limit to the number of FoamFatale Pressure Vessels connected to store the desired volume of the pressurized foam premix. And with the right design of the connecting piping, any desired foam application rate can be achieved.
2./ The different foam introduction method: the continuous linear nozzle (CLN).
All drops of the designed quantity of foam get into the storage tank.
A properly designed pipeline connects the FoamFatale pressure vessel, where the foam premix is stored, and the CLN, where the expanding foam exits. Imagine a curved tube mounted on the entire upper circumference of the storage tank. This pipe (e.g., DN200) has a continuous orifice a few millimeters wide facing the tank shell. The foam leaves the tube through this gap, which is directed at 45 degrees toward the inner side of the tank shell. This is the CLN.
Foam application rate, volume, pressure, dimensions, and topography are all crucial factors for successful storage tank fire extinguishment in any size storage tank within two minutes. This is the primary design criteria of all FoamFatale systems.
Eight parts of the short life of a storage tank fire
1 – the storage tank ignites
2 – the heat detectors detect the fire
3 – their sign opens the main valve
4 – the pressurized foam begins to expand in the pipeline
5 – the foam exits through the continuous linear nozzle and flows down the inner side of the tank shell
6 – the foam hits the surface of the liquid and runs further toward the center
7 – the foam front runs further toward the center of the tank
8 – the foam creates a wholly closed foam blanket
