SMALL DROPS, BIG IMPACT: FIREFIGHTING

SMALL DROPS BIG IMPAC

As water mist is an important element in the successful and efficient fight against fire, we have chosen the slogan “Small Drops, Big Impact.” Until now, however, its potential could only be exploited to a limited extent, as it was not possible to throw water mist at a long distance. By combining it with a turbine, we at EmiControls have solved this problem. Back in 2011, we were able to organize the largest documented fire test with water mist in Europe. Even then it was clear: the water mist turbine represents a paradigm shift in fire fighting. Today, everyone is talking about “sustainability”...

SMALL DROPS, BIG IMPACT THE EFFICIENCY OF WATER MIST The efficiency of water mist in fighting fires has been known in expert circles for years. Until now, the water mist was applied by means of nozzle technology, which, however, for technical reasons limited the throwing range to only a few meters. This, of course, also limited the range of possible applications. We at EmiControls have solved this problem: thanks to the use of a propeller turbine, the water mist can now be applied over a long distance. Why water mist works Water mist achieves a higher cooling effect when extinguishing fires and...

An example: If you spray 1 l of water into different droplet sizes the following happens: 1 mm diameter > heat absorption surface of 6 m² > heat absorption surface of 60 m² heat absorption surface of 600 m² The graph shows the relationship of droplet size to heat absorption surface: the heat absorption surface of 1 liter of water is inversely proportional to the diameter of the droplets it produces. Conclusion The characteristics of water mist allow efficient firefighting with minimal use of water: ›› more heat is extracted from the source of the fire ›› the cooling effect has a positive effect...

THE WORKING PRINCIPLES OF WATER MIST From a physical and thermodynamical point of view, there are several 1 water mist turbine Cooling effect Primarily the water mist efficiently cools the fire plume and the fuel surface, extracting a significantly high quantity of heat out of it. This happens thanks to the high latent heat mechanisms acting simultaneously, by which water mist extinguishes fire. conventional extinguishing method Heat Release Rate (MW) Tested Efficiency A test trial (carried out in 2011) clearly shows the differ- ence between the water mist turbine and a conventional extinguishing...

Inerting effect The water mist is carried with the air into the source of the fire, where it quickly evaporates due to the high heat. As a result of the enormous increase in the volume of the water droplets as they evaporate (up to 1,700 times), the oxygen at the source of the fire is displaced and the fire is smothered. N Additional positive secondary effects include: ›› gas suppression ›› burnt gas knock-down ›› personal protection (as water mist lowers the temperature and eliminates burnt gases faster than any other agent) ›› cooling of objects Absorption of radiant energy Water mist also...

SMALL DROPS, LARGE THROWING DISTANCE THE WATER MIST TURBINE The water mist turbine combines all the previously mentioned advantages of water mist with the power of a turbine: it thus represents a new and innovative generation of firefighting. Its unique selling point: the water mist turbine is capable of atomizing large quantities of water and distributing it over a large area, yet with pinpoint accuracy – and all this at low water pressure.

Our water mist turbines have a total of 4 patents: head monitor, internal monitor, valve and rail-way kit (for extinguishing robots). 20 Water mist turbines are already in use in 20 countries worldwide. 350  MW In 2011, we conducted the largest documented fire test with water mist in Europe. The heat release rate was 35

Water mist is a very versatile and particularly safe way of firefighting. Since our turbines can operate either as stationary fire protection and as mobile firefighting units – in the form of firefighting robots and fire truck solutions, there is a whole range of possible areas of application. Our solutions provide the following benefits in addition to emission reduction: Recycling ›› In case of a fire, the turbine starts operating immediately, Chemical Industry and Refineries ›› The water mist is indicated for ›› Suppression of toxic substances preventing the fire from operations on systems...
