Fire - is a real scourge of civilization and a pending problem to the world. It is hard to resist the analogy, that the fire is in fact an uncontrolled power of destruction. In this article, the author reveals the physical essence of a new method of electric-field suppression of uncontrolled processes of ignition and combustion flames. A specifial device for its implementation is provided, for example, forest fires, to prevent ignition of objects. It fully justifies a new promising method of suppressing and preventing fires of any complexity without consumables with an electrical method very efficiently and quickly.


Fires in forests, homes, businesses or expensive objects of oil and gas industry are a disaster for millions of people around the world- mainly for Australia the United States and other countries with arid zones. Fires cause enormous environmental damages and huge economic losses each year. Thousands of hectares of forests are destryed and hundreds of people die. Damages from fires only  within the CIS cost millions of dollars a year.
The concentration of toxic substances in the area of forest fires is much higher than permissible levels and the air is filled with acrid poisonous smoke.

So what's the difficulties of modern methods of fighting fires.
The fire is in fact an uncontrolled reaction and a conversion of chemical substances creating a lot of heat and smoke.
Unfortunately, existing methods of extinguishing forest and urban fires, including water spray and air are expensive and inefficient.
The persistence of effective control of large fires is fairly obvious.

The whole world has witnessed spectacular fires at the Ostankino TV tower in Moscow and the collapse of two giant skyscrapers in New York

Experts and officials call a lot of management and technical reasons for the difficulties of the struggle with the elements of fire (lack of equipment and water, wear and tear of equipment, difficulties extinguishing peat).
But the main reasons are the imperfections themselves of existing technologies for fire extinguishing. In the practice of fire suppression over the past 300 years the world had seen no radical innovations. Existing control technologies that reduce fire actually in lower flames use various substances like water, sand or foam.  Some substances that are injected into the combustion zone, knocking their flames and prevent the passage of oxygen into the combustion zone. Such fire-fighting technologies often  are ineffective.
Nevertheless, in recent years appeared quite original ideas and technologies  of electrical control combustion and flames.
Based on an elektro-fire technology  invented by the author in Russia, a radically new and efficient method for extinguishing fires and preventing fire flames was tested and patented. It is an contactless method of extinguishing the flames and descibes the devices for implementation.
This new method of extinguishing flames is based on a strong pulsed electric field with intensities of 5kV/cm and above. It can be effectively used as a fundamentally new way for contactless extinguishing flames. The purpose of this invention was to increase the efficiency and the speed of extinguishing flames, as well as in the prevention of fire particularly within important and costly facilities.


Let us explain in more detail the nature and physics of the new method.
Traditionally, flames (fire) stew with external blowing agents. The cost of extinguishing fires by traditional ways are high, the efficiency of quenching is often low and the losses of values and material with this method of suppression are high. In addition, these methods do not prevent the occurrence of ignition.

The proposed method is to create a constant external electric field within the flame zone. The intensity of this field depends on the type of the flames and its intensity and ranges between 2-25 kV/cm.
The method of electric flame suppression is based on the physical effect of the deviation of the flame to one of the oppositely charged high-capacity external electric field (see, for example, Vol. M. Faraday's "History of Candles" (translated from English.) М.1983 g.
The physical nature of the proposed method is ionizing the burning materials. In this way there exists a controlled combustion, which in particular can be used to extinguish the flames. Experiments show that the electric field even at low power can extinguish the flames within a certain distance in a  safe way for humans.
Burning is a complex process. It is based on physics of flow of fission chain reactions of charged radicals resposible for the ignition of the substance. Hence, the electric field for the quenching of flames creates precisely the conditions for cessation of the flow of the chain reactions of fission particles of burning fuel.

Disruption of the flame is essentially the breakdown of the percolation of chain reactions, breaking of hydrocarbon chains of substances at the source of ignition. Achieved in our method it is semi-definite electric field of a certain high tension (above 2 kV/cm). In this case, the external electric field with the specified threshold voltage "pulls" from the zone of occurrence of chain reactions (combustion zone) the electrons and oppositely electrically charged radicals burning of substances contained in the flame, by their rejection, and deposition of high heat resistant special electrodes placed in the combustion zone outside the flame and electrically connected to the outputs of an electrical high voltage converter.
As a result, in the combustion zone the conditions of maintaining the chain reaction of crushing radicals burning substances in the nucleus of the flame are violated, so the chain reaction of combustion of substances attenuate or even stop. Visually, there is the effect of avalanche breakdown of the flame.The flame ist extinguished, usually abruptly.


The practical realization of the proposed noncontact method of extinguishing flames and devices are fairly simple. It boils down to locate near the flashpoint a low-power (less than 1 kW) high-voltage source and one or more special electrodes that pass a field inside the hearth fire. With proper choice of limiting the external electric field in the combustion zone flame, sufficient to violate the maximum allowable combustion conditions of a specific substance - the flame is extinguished. As a rule, to extinguish the hearth fire of many common substances, sufficient field strength varies from 1 to 5 kV/cm.

A development of this invention in the device are different designs of electrodes and their connecting circuits to the high-voltage source. For example, one of the options for installing the fire-contact the refractory electrodes which is attached to the "+" high voltage source is placed directly into the combustion zone (Fig. 2). The second one is a ring electrode placed movably in the flame. Thus, insite that it was at a distance of 3-5 cm above the flame, and the extent of quenching, ie. reducing the height of the flame, bringing it to the top of the flame. With the sign "-" directly on the burning substance and the other movable electrode in the flame.
The simplest device for carrying out the invention, contains a source of external electric field, for example, an adjustable high-voltage rectifier and heat-resistant movable electrodes, which are located outside of the flame of the burning substances. To simplify the graphics, they are  are not shown in the figure.

The device operates as follows. To extinguish the flame, the power is connected to the input of the high-voltage transformer-rectifier and establishes a permanent external electric field in the combustion zone in the flame between the electrodes, located outside of the flame.  Depending onto the field strength and with a minimum distance under the terms of preventing electric breakdown of the high voltage source  through the flame  or the electrodes.
As a result, unlike electrically charged radicals and free electrons and the burning of chemically fragmenting in the process of burning materials which are contained in the flame, escape from the flames  and are attracted to their opposite electric charged electrode. If the electric field in the combustion zone,which is greater than 1 kV/cm, the conditions of occurrence of chain reactions of combustion and physical-chemical fragmentation of the substance in the flame becomes impossible and the flame abruptly is extinguished.

Experiments confirm, that the higher the strength of the external electric field, for example, about 10 kV/cm, the more effective and faster the flames are extinguished. In this case, the strength of the field can be changed or the output voltage unit is regulated, or the distance between the electrodes is increased.


Experiments show that the higher the strength of the external electric field, the higher the speed of the breakdown of the flame and the higher is the speed of extinguishing the flame. The greater the surface area of the electrodes, the greater the area of possible extinguishing the flames in an aprupt way.
The experiments also show that the most efficient implementation of the proposed method is when the extinguishing of the electrode surface area is equal to the projection of the flame in the same plane. And electric power source voltage suppression is almost independent of the power of the flame, but is determined only by internal losses in the voltage source, ie negligible compared to the power of the flame in the hearth fire. For example, when extinguishing the flame of a height of 1 m: It tooks 3 seconds of time and an electrical power of 3.4 watts when the electric field strength is 3.5 kV/cm.

An efficient method for extinguishing the flame, is‘nt it?



A development in the field of suppressing the electrode is to put out fires in a large area by the smooth movement of the opposite sign of electric charge on the flat electrode connected to the source of an external electric field in the fire zone directly over the flame fast enough to disrupt and suppress the flame.

In this regard, it is possible to create an option for mobile devices for contactless extinguishing the flames, for example, at forest or peat fires.
In this case, a special mobile equipment, eg an helicopter a truck or a vehicle with high cross-type "Ural" supply, the source of the regulated high voltage are specialized mobile blanking electrodes with are armed with high-voltage wires with increasing strength as well with telescopic masts, which are mounted on electrical insulators above the electrodes. These are electrically connected to the onboard extinguishing source of high voltage electrodes, such as delicate thin heat-resistant metal mesh on special stretch frames, posted on telescopic poles. These ban in the combustion zone in various ways and extinguish the fire.
They are housed for example horizontally over the flames in the combustion zone with a special fine mesh stretched on a metal grid, connected via electrical insulators with "+" output of high voltage source, posted on board the helicopter, and the second electrode, such as flexible thin rope with the opposite "- "electrical potential is lowered directly into the flame. After the pulsed electric-field breakdown of the flame and extinguish the specific focus of the flame in a few seconds at a given location, the helicopter is moved to the next hearth fire.


Moving at a certain speed, the flame front in the course of its spread gradually and completely disappears while approaching to such an electric fence. The main thing in such way to stop the fire front without water and foam is only in the fact that the area coverage of such electrical panel fire zones is complete, ie that it was no less than the square and the length of the front fire. With localization of the source of ignition in time, it makes it relatively easy.
This method of insulation of the flame front in the suburbs adjacent to forest areas is very important for protection of residential buildings and businesses.

To do this, this mobile installation of electric fire should be quicly deployed  in a fire zone by a mobile system to place the electrodes on the perimeter of the zone of fire. Then the command chief of the facility has to take people into a safe distance from the source of ignition and apply high voltage to the system of electrodes.
A special case of a rapid deployment of electrodes in the zone of fire is a special pneumatic ejection device in the zone of fire.


The essence of this technical possibility is that the electric field suppresses the foci of fission chain reactions in the zone of fire. Opportunity to clarify the application of this invention as effektive firefighting resources.


Indeed, if such a system of electrodes and a source field and sensors placed near the fire in advance of the protected object, the whole technology of suppression of ignition in the initial stage will be reduced only to a voltage to the electrodes on command sensors.
Moreover, as the source of the electric field can use special thin plastic coated- polymer electrets having long persisting "frozen" with their electric charges.

Production and use of electrets are already widely utilized and they are widely used in the means of telecommunication (telephones, microphones), and are inexpensive.
In this case, the application of polymer sources of electric fields and the implementation of these electrodes fully extinguish the flames without the question of electrical safety.

You can also place them within the most vulnerable sites in advance to create an external electric field of this tension surrounding important objects, such as homes, apartments, around a bank safe deposit box, power transformer with oil, the oil rig at the mouth of the borehole, etc.
In the active zone of the electric field conditions of ignition of substances will be difficult. As a result, ignition of flames by potential flashpoint substances, for example, by cutting the pipe rig becomes impossible.
Therefore this invention is useful to apply as a preventive fire-fighting tool. For example  in constructions of the oil industry or especially in newly constructed buildings and structures.
It is the best way to use such devices for high fire risk or valuable objects or
also in the areas of high fire danger.
For example, to prevent fires and peat fires in Moscow . To do this, there must be placed a ring of elektro-fire security around the capital .
Namely to implement this method in practice on a wide area of fields and woodlands to create a system of electrically connected electrodes embedded in peat bogs in areas most likely for ignition and connect them through the automatic switches to the backup source of high voltage, for example, through special complete devices to high-voltage power lines. Detection of outbreak of fire may be done sensors and smoke sensors or other ways of warning for
the presence of smoke and fire in the hearth.
Then if a fire-ring system of these pre-defined electrodes around the most vulnerable places of summer peat fire it will be easy to suppress the ignition at the beginning of this process.
It's enough to hae a system of autonomous ring electrodes in a given local ring of fire. Calculations and experiments show that the corrosion resistant and heat-resistant electrodes are to be placed at a distance of 50-100 m relative to each other.


Thus, the Electro technology extinguishing the flames is a new effective fire-fighting equipment which can also be successfully applied in a non-contact instantaneous suppression of ignition and prevent fire in important objects.
In  the latter case, the installation of electrical field is to be assembled in advance as a means within the potential zone of fire, for example, in the area of peatland near Moscow, and on specific important sites, such as high-rised buildings with expensive equipment or on oil rigs and other important facilities, including building design of any number of storeys, including and industrial enterprises.
