Fire extinguishing process off-line.
Wind Turbine Developers often claim that their technology is safe, and whenever
there has been a wind turbine fire, or other form of serious accident, the developer
is often quick to state that this is a rare occurrence. Yet you only have to look at
insurers reports to get a better understanding of accident rates and insurance
claims made by wind energy developers to get a truer account of the health and
safety aspect of turbines.
Caithness Wind Farms have compiled a detailed report on wind farm accidents
throughout the UK and internationally, by sourcing news articles, accident reports
and insurance documents.
They state that: Fire is the second most common accident cause in incidents found.
Fire can arise from a number of sources – and some turbine types seem more prone
to fire than others.
A total more than 300 fire incidents were found.
The biggest problem with wind turbine fires is that, because of the turbine height,
the fire brigade can do little but watch it burn itself out. While this may be
acceptable in reasonably still conditions, in a storm it means burning debris being
scattered over a wide area, with obvious consequences. In dry weather there is
obviously a wider-area fire risk, especially for those constructed in or close to
forest areas and/or close to housing or work places.
You need three things to start a fire: fuel, ignition and oxygen. And you can find all
three of them in ample quantities within the nacelle of a wind turbine.
A 1.5MW machine, on the small side by today's standards, can still contain up to
900 liters of lubricating and cooling oil. The nacelle itself, probably made with
flammable fibre-reinforced plastic (FRP), will house acoustic insulation materials,
which are also flammable. Ignition can be provided by faulty electrical and
electronic components and connections, or overheating mechanical parts. And high
winds, the reason the turbine is there in the first place, can be guaranteed to feed
the spark and fan the flames.
Once a fire takes hold there is practically nothing that can be done to prevent the
turbine's complete destruction. The remote location of many wind projects means
that fire-fighting services are often slow to arrive the scene, while the nacelle's
height rules out any meaningful action for fire suppression. The best that can be
expected is that burning debris is prevented from starting ground fires.
WATERFOAM FULL AUTONOMOUS FIREFIGHTING SYSTEM WITHOUT PRESUURE, ENGINES AND
OUTHER WATER OR POWER SOURSE.
Other Firefighting System for Wind Turbine have:
1. Water or foam premix stored under high pressure in the pressure
vessel, not less 16 bar.
2. Big size pressure vessel.
3. Difficult design and expensive service.
4. Impossibility of fast recharge.
5. Big time delay between the breakout the fire and the actuation of the
6. Need of use only of one type of foam.
7. High price full complete equipment and service.
Parameters systems Impulse Storm-A
• Volume premix foam vessel - 800 liters
• Delay between the breakout the fire and the actuation system - 0,5 –
• After the actuation, the extinguishment time is done - 25 seconds
• Pressure stand-bay mode – zero.
• Time stand-bay mode without service and recharge – not less 5 years.
• External power or water source – not need.
• Opportunity to dispersion firefighting powder or water only - yes
• Type foam use – any.
• Time recharge - 30 minutes
• Staff for recharge and service - users staff
The main advantages over any other system of fire extinguishing and cooling:
1. Very low sluggishness - less than a second.
2. Very little time before complete extinguishing - just a few seconds.
During this timeframe fire is unable to warm up the transformer oil and metal
structures, which excludes the spread of fire and re-ignition.
3. The lack of any external pressure source, pump stations, external
piping or external water tanks.
4. Absence of any pressure in the system in a Standby mode.
5. The absence of any external and internal sources of electrical power.
The system is fully autonomous for at least 10 years (the term of more
than 10 years has not been tested).
8. Synchronous not less three fire extinguishing agent - neutral gas, water and foam in
