New Scientific Results, Propositions
1. We introduced a new concept namely the foam effectiveness factor in order to facilitate the contrasting survey of tank fire extinguishing technologies.
The foam exploitation factor being a rating number shows how efficiently the certain technology uses the total foam volume for the extinguishing. Introducing it and defining it numerically enables us to compare the well-known technologies and choose the Best Available Technique keeping the burning time in mind and apply it with full environmental awareness.
2. We extended the scope of examining foam spreading phenomena by creating the curve of the penetration speed and the foam profile and analysing and defining the geometrical coherence of foam introduction.
The key method of the research was the theoretical study of foam spreading. Having created these definitions we developed the most effective foam introduction solution that could perform a successful fighting even in case of largest tank size.
3. We discovered the physical explanation for a well-known phenomenon namely the wall-effect and explained the anomalies experienced during extinguishing the fire.
The wall-effect as a well known phenomenon has been rendering the extinguishing more difficult for years. Having discovered its physical-mathematical explanation we could find the most efficient way of foam introduction.
4. We propose to develop a new extinguishing technology and apparatus of storage tank fires based on the updated environmental safety regulations. Furthermore we propose to update the tactical instructions of extinguishing in order to reduce air and above and underground water pollution caused tank fires and their extinguishing process.
All the new extinguishing parameters mentioned above along with the new approach of extinguishing give us the right to introduce the ISO 14001 standard, an environmental aware management into the surface of the disaster recovery.
5. We developed a technical proposal to solve the problems of fighting tank fire in sites lacking of any water supply and a fire brigade and we evolved an extinguishing control system operating with multi-detector without external auxiliary energy supply.
In this way extinguishing becomes possible even under circumstances where all traditional strategies seem to fail. This system can even be deployed at places without fire water supply, military deployment sites, provisional fuel tanks, storage sites in a desert or in exposed places. The risk of false start-up was reduced by developing an autonomous extinguishing control that requires no auxiliary energy.
