Abstract

The invention is for a method for firefighting in which a directed jet of extinguisher foam is applied so as to cover the source of the fire, and to a device suitable for implementing this method. The method and device make it possible to extinguish fires which are spreading in area, while at the same time reducing the risk of uncontrolled spread of the fire. According to the invention, this is achieved in that as a supplement to the jet of extinguisher foam, the apparatus discharges individual jets of a mist of firefighting liquid which cools down the space surrounding the source of the fire.

Description

Verfahren und Vorrichtung zum Bekämpfen von Bränden Fire fighting method and apparatus
Die Erfindung betrifft ein Verfahren zum Bekämpfen von Branden, bei dem ein gerichteter Loschschaumstrahl ausgebracht wird, um den Brandherd abzudecken. Darüber hinaus betrifft die Erfindung eine Vorrichtung, welche zur Durchfuhrung des Verfahrens geeignet ist. Derartige Vorrichtungen werden in stationären oder mobilen Feuerloscheinrichtungen eingesetzt, um einen Brand durch einen Schaum zu ersticken, wenn beispielsweise der Einsatz von Wasser als Losch lussigkeit nicht möglich ist .The invention relates to a method for fighting fires, in which a directed jet of foam is applied in order to cover the source of the fire. Furthermore, the invention relates to a device which is suitable for carrying out the method. Devices of this type are used in stationary or mobile fire extinguishing devices in order to suffocate a fire through a foam, for example if the use of water as a liquid is not possible.
Eine zum Loschen von Branden mit Loschschaum geeignete Vorrichtung ist aus der britischen Patentschrift 1 018 431 bekannt. Die in dieser Druckschrift beschriebene Vorrichtung weist ein Schaumrohr auf, welches mit einem zylindrischen Abschnitt einen Dusenkorper umgibt. Der Dusenkorper hat eine Düse, aus der Loschflussigkeit ausgebracht wird. Zum Einlassen von Umgebungsmedium besitzt die bekannte Vorrichtung auf ihrer rückwärtigen Stirnseite eine Eintrittsoffnung . Zusatzlich sind mehrere Eintrittsoffnungen auf dem zylindrischen Umfang des Schaumrohrs verteilt.A device suitable for extinguishing fires with foam is known from British Patent 1,018,431. The device described in this document has a foam tube which surrounds a nozzle body with a cylindrical section. The nozzle body has a nozzle from which liquid is discharged. To admit ambient medium, the known device has an inlet opening on its rear face. In addition, several inlet openings are distributed over the cylindrical circumference of the foam tube.
Der mittels einer solchen Vorrichtung erzeugte Loschschaum läßt sich in einem gerichteten Strahl ausbringen. Dies hat den Vorteil, daß der Loschschaum mit relativ hoher kinetischer Energie austritt, so daß erThe erasing foam produced by means of such a device can be discharged in a directed jet. This has the advantage that the foam is released with relatively high kinetic energy, so that it
BESTATIGUNGSKOPIE große Wurfweiten überbrücken kann und der Brand zunächst aus großer Entfernung niedergeschlagen und anschließend aus geringerem Anstand abgelöscht werden kann. Gleichzeitig wird durch die konzentrierte Ausbringung des Löschschaumstrahles bewirkt, daß der Schaum in kompakter Form auf die Brandstelle auftrifft und nach dem Auftreffen eine dichte Abdeckung bildet, durch welche der Brand erstickt wird.CONFIRMATION COPY can cover large throwing distances and the fire can first be put down from a great distance and then extinguished from a short distance. At the same time, the concentrated application of the extinguishing foam jet causes the foam to hit the fire site in a compact form and, after impact, forms a tight cover through which the fire is suffocated.
Die starke, im Hinblick auf die Überbrückung großer Wurfweiten und die gute Wirksamkeit des Löschschaums gewünschte Konzentrierung des Löschschaumstrahles erweist sich in der Praxis jedoch dann als problematisch, wenn Brände bekämpft werden müssen, die sich über große Flächen ausbreiten oder ein großes, kompaktes Volumen, wie beispielsweise einen Holz- oder Papierstapel größeren Umfangs, erfaßt haben. Derartige Brandherde können mit einem gerichteten Löschschaumstrahl nur dadurch bekämpft werden, daß während des Löschens mit demThe strong concentration of the extinguishing foam jet, which is desired with regard to bridging large throwing distances and the good effectiveness of the extinguishing foam, proves to be problematic in practice when it is necessary to fight fires that spread over large areas or a large, compact volume, such as for example, a large stack of wood or paper. Such sources of fire can only be combated with a directed extinguishing foam jet in that with the
Löschschaumstrahl wedelnde Bewegungen ausgeführt werden. Durch diese Bewegungen überstreicht der Strahl die Brandfläche, so daß diese nach einiger Zeit mit Löschschaum überdeckt ist. In der Praxis zeigt sich jedoch, daß dabei wegen der nur unvollkommenen Abschottung des Brandes und der hohen Umgebungstemperatur eine Ausweitung des Brandes auf benachbarte Bereiche und Gegenstände nicht immer verhindert werden kann.Extinguishing foam jet wagging movements are carried out. Through these movements, the jet sweeps over the fire area, so that after some time it is covered with extinguishing foam. In practice, however, it turns out that because of the incomplete partitioning of the fire and the high ambient temperature, an expansion of the fire to neighboring areas and objects cannot always be prevented.
Die Aufgabe der Erfindung besteht darin, ein Verfahren der eingangs genannten Art und eine zur Durchführung des Verfahrens geeignete Vorrichtung anzugeben, welche das Löschen von flächig sich ausbreitenden Bränden bei vermindertem Risiko einer Brandausbreitung ermöglichen. Bezüglich des Verfahrens wird diese Aufgabe dadurch gelöst, daß ergänzend zu dem Löschschaumstrahl ein Loschflussigkeitsnebel ausgebracht wird, welcher das den Brandherd umgebende Raumvolumen abkühlt.The object of the invention is to provide a method of the type mentioned at the outset and a device which is suitable for carrying out the method and which allow the extinguishing of spreading fires with a reduced risk of fire spreading. With regard to the method, this object is achieved in that, in addition to the extinguishing foam jet, an extinguishing mist is applied, which cools the volume of space surrounding the source of the fire.
Das erfindungsgemaße Verfahren kombiniert das beispielsweise aus dem deutschen Gebrauchsmuster 295 18 911.8 an sich bekannte Loschverfahren unter Verwendung von Loschnebel mit dem Verfahren zum Loschen mittels eine Loschschaums. Es hat sich gezeigt, daß sich der Loschnebel und der Löschschaumstrahl in optimaler Weise insbesondere bei der Bekämpfung von großflächigen oder großvolumigen Brandherden erganzen. Dies geschieht dadurch, daß zum einen durch den Einsatz des gerichteten Loschstrahls der Brand unmittelbar bekämpft und die Brandoberflache sukzessive mit Schaum abgedeckt wird. Zum anderen wird durch den Loschnebel der Gasraum abgekühlt, welcher den Brand umgibt. Da der Loschnebel einen wesentlich größeren Raum erfaßt als der Loschschaumstrahl, wird durch die Einbringung des Loschnebels erreicht, daß die Umgebungstemperatur des Brandes auch in solchen Bereichen dann schon abgesenkt wird, wenn eine direkte Abdeckung des Brandes durch den Loschschaum noch nicht erfolgt ist, wenn das Feuer in den betreffenden Bereichen also noch brennt. Eine Ausbreitung des Brandes, beispielsweise durch Selbstentzündung von zum Brandherd benachbarten Gegenstanden in Folge der hohen Temperaturen in der Umgebung des Brandes wird so vermieden .The method according to the invention combines the extinguishing method known per se, for example from German utility model 295 18 911.8, using extinguishing mist with the method for extinguishing by means of an extinguishing foam. It has been shown that the extinguishing mist and the extinguishing foam jet complement each other in an optimal manner, particularly when fighting large-scale or large-volume sources of fire. This happens because, on the one hand, the fire is fought directly by using the directed extinguishing jet and the surface of the fire is successively covered with foam. On the other hand, the gas space that surrounds the fire is cooled by the loosening mist. Since the extinguishing mist covers a much larger area than the extinguishing foam jet, the introduction of the extinguishing mist ensures that the ambient temperature of the fire is reduced even in such areas if the fire has not yet been directly covered by the extinguishing foam, if that Fire in the relevant areas is still burning. This prevents the fire from spreading, for example due to self-ignition of objects adjacent to the source of the fire, as a result of the high temperatures in the vicinity of the fire.
Besonders vorteilhaft ist es, wenn das Ausbringen des Loschnebels wahlweise in Abhängigkeit von der Stellung einer Steuereinrichtung erfolgt. Dies ermöglicht es, die in den Bereich des Brandherdes eingebrachten Loschmittel (Loschschaum / Loschflussigkeitsnebel) in Abhängigkeit von der jeweiligen Brandsituation zusammenzustellen.It is particularly advantageous if the loosening mist is deployed optionally depending on the position of a control device. This enables the extinguishing agents introduced into the area of the fire (Extinguishing foam / extinguishing liquid mist) depending on the respective fire situation.
Besonders vorteilhaft einsetzen laßt sich das erfindungsgemaße Schaumrohr m Verbindung mit Loscheinrichtungen, bei denen die Loschflussigkeit unter hohem Druck, d.h. bei Drucken oberhalb 40 bar, ausgebracht wird.The foam pipe according to the invention can be used particularly advantageously in connection with quenching devices in which the quenching liquid is under high pressure, i.e. at pressures above 40 bar.
Eine weitere vorteilhafte Ausgestaltung des erfmdungsgemaßen Verfahrens ist dadurch gekennzeichnet, daß Loschflussigkeitsnebel m Form von mehreren Einzelstrahlen ausgebracht wird, deren jeweiliger Ursprung in unmittelbarer Nahe des Ursprungs des Loschschaumstrahles angeordnet ist. So kann auf einfache Weise sichergestellt werden, daß derA further advantageous embodiment of the method according to the invention is characterized in that mist liquid is applied in the form of several individual jets, the respective origin of which is arranged in the immediate vicinity of the origin of the mousse foam. So it can be easily ensured that the
Loschflussigkeitsnebel mit seinem größten Anteil jeweils stets den Abschnitt des Feuers umhüllt, welcher aktuell durch den Loschschaumstrahl abgedeckt wird. Daher ist diese Ausgestaltung insbesondere dann vorteilhaft, wenn das erfindungsgemaße Verfahren mit einer mobilen Feuerloscheinrichtung ausgeführt wirα, bei welcher der Feuerwehrmann eine mobile Loschpistole m der Hand halt. Besonders gunstig ist es m diesem Zusammenhang, wenn ein Teil der Einzelstrahlen des Loschflussigkeitsnebels m Richtung des Brandherdes gerichtet ist, wahrend ein anderer Teil normal zur Achse des Loschschaumstrahles ausgerichtet ist. Auf diese Weise wird ein vergrößertes Raumvolumen mit Flussigke tsnebel gefüllt, so daß nicht nur der Raum im unmittelbaren Umfeld des Brandes abgekühlt wird, sondern auch die m die Umgebung aufsteigenden Abgase. Gunstig ist es dabei, wenn ergänzend oder alternativ mindestens ein Einzelstrahl m eine vom Brandherd abgewandte Richtung gerichtet ist, so daß auch der Rückraum der Lόscheinrichtung vom Loschnebel sicher erfaßt wird.Clearance mist with its largest proportion always envelops the section of the fire that is currently covered by the clearing foam jet. This embodiment is therefore particularly advantageous when the method according to the invention is carried out with a mobile fire extinguishing device in which the fireman holds a mobile fire extinguishing gun in his hand. In this context, it is particularly advantageous if some of the individual jets of the clearing liquid mist are directed in the direction of the source of the fire, while another part is aligned normal to the axis of the clearing foam jet. In this way, an enlarged volume of space is filled with liquid fog, so that not only the space in the immediate vicinity of the fire is cooled, but also the exhaust gases rising in the environment. It is advantageous if, in addition or as an alternative, at least one single jet is directed in a direction away from the source of the fire, so that the rear area of the extinguishing device is also reliably seized by the release mist.
In praktischen Versuchen hat sich gezeigt, daß sich das erfindungsgemäße Verfahren dann besonders wirkungsvoll einsetzen läßt, wenn die Loschflussigkeit , aus welcher der Loschflussigkeitsnebel erzeugt wird, Wasser ist.Practical tests have shown that the method according to the invention can be used particularly effectively when the liquid from which the liquid mist is generated is water.
Eine zur Durchf hrung des erfindungsgemaßen Verfahrens besonders geeignete Vorrichtung, welche mit einem Loschdusenkopf ausgestattet ist, der eine Loschschaumerzeugungseinrichtung zum Erzeugen eines gerichteten Lόschschaumstrahls umfaßt, ist erfindungsgemäß dadurch gekennzeichnet, daß der Loschdusenkopf zusätzliche Loschdusen zum Erzeugen von Löschtlussigkeitsnebelstrahlen umfaßt. Dabei kann vorzugsweise mindestens eine der Loschdusen derart ausgerichtet sein, daß der aus ihr austretende Loschflussigkeitsnebelstrahl in Richtung des Brandherdes gerichtet ist, während mindestens eine weitere Loschnebelduse derart ausgerichtet ist, daß der aus ihr austretende Loschflussigkeitsnebelstrahl in einer normal zur Austrittsrichtung des Loschschaumstrahles gerichtete Richtung austritt.A device which is particularly suitable for carrying out the method according to the invention and which is equipped with an eraser nozzle head which comprises an eraser foam generating device for producing a directed eraser foam jet is characterized in accordance with the invention in that the eraser nozzle head comprises additional eraser nozzles for generating erasing liquid mist jets. At least one of the quenching nozzles can preferably be oriented such that the quenching liquid spray emerging from it is directed in the direction of the source of the fire, while at least one further quenching nozzle is oriented such that the quenching liquid spray emerging from it exits in a direction normal to the exit direction of the clearing foam jet.
Weitere Ausgestaltungen der Erfindung sind in den abhangigen Ansprüchen angegeben und werden in der nachfolgenden Beschreibung eines Ausfuhrungsbeispiels anhand einer Zeichnung naher erläutert. Die einzige Figur zeigt eine transportable Lόschpistole L in einer teilweise aufgebrochenen Seitenansicht.Further embodiments of the invention are specified in the dependent claims and are explained in more detail in the following description of an exemplary embodiment with reference to a drawing. The single figure shows a portable fire gun L in a partially broken side view.
Der Loschdusenkopf 1 der transportablen Löschpistole L ist rotationssymmetrisch aufgebaut und weist auf seiner Stirnseite eine Stirnflache 2 auf. Im Zentrum der Stirnflache 2 ist eine zentrale Loschduse 3 angeordnet. Die zentrale Loschduse 3 ist mit einer ersten Versorgungsleitung 4 der Loschpistole L verbunden, welche im Gehauserohr R der Loschpistole L verlauft.The Loschdusenkopf 1 of the portable fire gun L is rotationally symmetrical and points to it End face an end face 2. In the center of the end face 2, a central nozzle 3 is arranged. The central nozzle 3 is connected to a first supply line 4 of the nozzle L, which runs in the housing tube R of the nozzle L.
An die Stirnflache 2 des Loschdusenkopfes 1 angeformt ist eine umlaufende Schragflache 5, die gegenüber der vorderen Stirnflache 2 in einem Winkel α von annähernd 45° zurückweicht. Auf der Schragflache 4 sind Loschdusen 6 angeordnet, welche mit einer zweiten, ebenfalls in dem Gehauserohr R verlaufenden Versorgungsleitung 7 der Loschpistole L verbunden sind. Die Loschdusen 6 sind in regelmäßigen Winkelabstanden zueinander auf einem Kreis angeordnet, der konzentrisch zur Öffnung der zentralen Loschduse 3 ausgerichtet ist. Die Austrittsπchtung des aus ihnen bei Druckbeaufschlagung mit Loschflussigkeit austretenden Nebelstrahls ist im wesentlichen rechtwinklig zur Schragflache 5 gerichtet, so daß die Nebelstrahlen der Loschdusen 5 im wesentlichen in dieselbe Richtung gerichtet sind wie der achsparallel zur Langsachse X des Loschdusenkopfes 1 austretende Strahl, der durch die zentrale Loschduse 3 erzeugt wird.A circumferential inclined surface 5 is formed on the end face 2 of the Loschdusenkopf 1, which backs away from the front end face 2 at an angle α of approximately 45 °. Loose nozzles 6 are arranged on the inclined surface 4 and are connected to a second supply line 7 of the lance gun L, which also runs in the housing tube R. The loosening nozzles 6 are arranged at regular angular intervals from one another on a circle which is aligned concentrically with the opening of the central loosening nozzle 3. The outlet of the fog jet emerging from them when pressurized with loosening liquid is directed essentially at right angles to the inclined surface 5, so that the fog jets of the nozzle nozzles 5 are directed essentially in the same direction as the axis emerging parallel to the longitudinal axis X of the nozzle nozzle 1, which passes through the central one Loschduse 3 is generated.
Über ein handverstellbares Ventil V können die Versorgungsleitungen 4,7 gleichzeitig oder einzeln mit Loschfluid beaufschlagt werden.The supply lines 4, 7 can be supplied with extinguishing fluid simultaneously or individually via a manually adjustable valve V.
An die Schragflache 5 schließt sich eine radial umlaufende, achsparallel zur Langsachse X des Loschdusenkopfes 1 verlaufende Mantelflache 8 an, auf der weitere, mit der Versorgungsleitung 7 verbundene Loschdusen 9 angeordnet sind. Die Loschdusen 9 geben bei Beaufschlagung mit Loschfluid ebenfalls einen Loschnebelstrahl ab. Dieser weist jedoch eine radial zur Langsachse X des Loschdusenkopfes 1 gerichtete Komponente und eine in Richtung des Ventils V gerichtete Komponente auf, so daß die aus den Loschdusen 9 austretenden Loschnebelstrahlen den rückwärtig und seitlich die Loschpistole L umgebenden Raum ausfüllen.The inclined surface 5 is adjoined by a radially circumferential jacket surface 8, which extends axially parallel to the longitudinal axis X of the squeegee head 1 and on which further sockets 9 connected to the supply line 7 are arranged. The quenching nozzles 9 also give one when the quenching fluid is applied Quenching jet. However, this has a component directed radially to the longitudinal axis X of the nozzle nozzle 1 and a component directed in the direction of the valve V, so that the nozzle mist jets emerging from the nozzle nozzles 9 fill the space surrounding the nozzle L from the rear and to the side.
Auf der zentralen Loschduse 3 ist über ein Hülse 10 ein Schaumrohr 11 befestigt. Das Schaumrohr 11 weist einen Dusenkorper 12 auf, an dem eine in das Schaumrohr 11 ragende Injektorduse 13 ausgebildet ist. Die Bohrung 14 der Injektorduse 13 ist über eine Kammer des Dusenkorpers 11 und die Hülse 10 mit der zentralen Loschduse 3 verbunden. Zwischen der Wandung des Schaumrohres 11 und dem Dusenkorper 12 sind hier nicht dargestellte Emtrittsoffnungen ausgebildet, über die Umgebungsluft in das Schaumrohr gesaugt wird.A foam tube 11 is attached to the central nozzle 3 via a sleeve 10. The foam tube 11 has a nozzle body 12 on which an injector nozzle 13 projecting into the foam tube 11 is formed. The bore 14 of the injector nozzle 13 is connected to the central valve nozzle 3 via a chamber of the nozzle body 11 and the sleeve 10. Between the wall of the foam tube 11 and the nozzle body 12, exit openings (not shown here) are formed, through which ambient air is drawn into the foam tube.
In Abhängigkeit von der Stellung des Ventils V werden die Versorgungsleitungen 4 oder 7 gleichzeitig oder einzeln mit Loschfluid, vorzugsweise Wasser, beaufschlagt. Das Loschfluid weist dabei in beiden Versorgungsleitungen eine hohen Druck von mehr als 40 bar auf. Bei Druckbeaufschlagung der Versorgungsleitung 4 erzeugen die Loschdusen 6 und 9 einen Loschnebel, bei dem die einzelnen Flussigkeitstropfchen ein geringes Volumen aufweisen und fein verteilt mit hoher kinetischer Energie aus den Dusenoffnungen der Loschdusen 6,9 in die Umgebung austreten. Dabei erreichen die aus den schräg nach vorne weisenden Loschdusen 6 austretenden Nebelstrahlen die Umgebung des Brandherdes und kühlen die dort vorhandenen Gase unter Verdampfen und damit einhergehender Verdrängung des Sauerstoffes ab. Die aus den Loschdusen 9 der Mantelflache 8 austretenden Strahlen füllen demgegenüber den seitlichen und rückwärtigen Raum mit Loschnebel, so daß auch dort eine effiziente Herabsetzung der Temperatur erreicht wird. Auf diese Weise wird nicht nur ein Übergreifen des Brandes auf den abgekühlten Bereich verhindert, sondern der die Loschpistole bedienende Feuerwehrmann gleichzeitig geschützt.Depending on the position of the valve V, the supply lines 4 or 7 are simultaneously or individually supplied with extinguishing fluid, preferably water. The extinguishing fluid has a high pressure of more than 40 bar in both supply lines. When the supply line 4 is pressurized, the loosening nozzles 6 and 9 generate a loosening mist in which the individual liquid droplets have a small volume and emerge into the environment in finely divided form with high kinetic energy from the nozzle openings of the loosening nozzles 6,9. The mist jets emerging from the obliquely forwardly pointing nozzles 6 reach the surroundings of the source of the fire and cool the gases present there with evaporation and the associated displacement of the oxygen. Fill the jets emerging from the nozzle 9 of the jacket surface 8 In contrast, the side and rear room with Loschnebel, so that there is an efficient reduction in temperature. This not only prevents the fire from spreading to the cooled area, but also protects the firefighter who is using the fire pistol.
Bei Druckbeaufschlagung der Versorgungsleitung 7 wird aus der zentralen Loschduse 4 ein gerichteter, mit schaumbildendem Additiv vermengterWhen the supply line 7 is pressurized, the central outlet nozzle 4 becomes a directional one which is mixed with a foam-forming additive
Loschflussigkeitsstrahl, unter hohem Druck aus der zentralen Loschduse 3 ausgebracht. Dieser Strahl tritt in die Kammer des Dusenkorpers 12 des Strahlrohres 11 und wird dort zusatzlich verwirbelt. Der so verwirbelte Loschfluidstrahl tritt über die Dusenbohrung 13 m das Schaumrohr 11, in welches er nach Art des Venturi-Effekts Luft über die Eintrittsoffnungen des Schaumrohres einsaugt. Diese Luft vermischt sich mit dem fein zerstaubten Loschfluid unter Ausbildung eines feinporigen Schaums. Dieser Schaum tritt mit hoher kinetischer Energie aus dem Schaumrohr 11 aus und erreicht als gerichteter, kompakter Loschschaumstrahl den Brandherd.Loosening liquid jet, discharged from the central loosening nozzle 3 under high pressure. This jet enters the chamber of the nozzle body 12 of the jet pipe 11 and is additionally swirled there. The swirled extinguishing fluid jet passes through the nozzle bore 13 m into the foam tube 11, into which it draws air in via the inlet openings of the foam tube in the manner of the Venturi effect. This air mixes with the finely atomized quenching fluid to form a fine-pored foam. This foam emerges from the foam tube 11 with high kinetic energy and reaches the source of the fire as a directed, compact foam foam jet.
Durch das kombinierte Zusammenwirken der Abdeckung des Brandherdes durch den gerichteten Loschschaumstrahl und der Abkühlung der den Brandherd umgebenden Raums durch den Loschfluidnebel wird die Gefahr eines Ubergreifens des Brandes auf zum Brandherd benachbarte Bereiche oder Gegenstände deutlich vermindert. Ebenso ist durch die Abkühlung der Umgebungstemperatur die Belastung und Gefahrdung des Feuerwehrmanns wahrend des Loschens herabgesetzt . Zur Durchführung des erfindungsgemaßen Verfahrens wird als Loschflüssigkeit vorzugsweise Wasser eingesetzt. Die dem Wassernebel anhaftenden Vorteile der Warmebindung und der exzellenten Inertisierung sowie derThe combined interaction of the fire source cover by the directed extinguishing foam jet and the cooling of the area surrounding the source of the fire by the extinguishing fluid mist significantly reduces the risk of the fire spreading to areas or objects adjacent to the source of the fire. Likewise, due to the cooling of the ambient temperature, the load and danger to the fireman during the extinguishing is reduced. To carry out the method according to the invention, water is preferably used as the quenching liquid. The advantages of heat binding and excellent inerting as well as the inherent advantages of the water mist
Strahlungswarmeschutz für das Bedienungspersonal erhohen die Effektivität und Einsatzfahigkeit des durch den auf die Zentralduse aufgesetzten Hochdruckschaumerzeuger generierten Schaums.Radiation heat protection for the operating personnel increases the effectiveness and usability of the foam generated by the high-pressure foam generator placed on the central nozzle.
Besonders hervorzuheben ist, daß das Schaumrohr 12 auch dann zu einer erheblichen Verbesserung der Wurfweite des aus ihm austretenden Loschmittelstrahles führt, wenn dem Loschmittel kein schaumerzeugendes Additiv beigemischt ist, sondern lediglich die Loschflussigkeit selbst als Strahl von hoher kinetischer Energie aus dem Schaumrohr 12 austritt. Die Verwendung des Schaumrohrs 12 beim reinen Flussigkeitsloschen ist dann gunstig, wenn beispielsweise ein gerichteter Loschflussigkeitsstrahl benotigt wird, um aus größerer Entfernung den Brandherd zu erreichen. Darüber hinaus kann der durch das Schaumrohr konzentrierte Loschflussigkeitsstrahl dazu benutzt werden, eine Benetzung von auch tief im Innern des Brandherdes verborgenen Glutnestern durch einen gezielten Strahl zu erreichen. It should be particularly emphasized that the foam tube 12 also leads to a considerable improvement in the throwing distance of the extinguishing agent jet emerging from it when no foam-generating additive is added to the extinguishing agent, but only the extinguishing liquid itself emerges from the foam tube 12 as a jet of high kinetic energy. The use of the foam tube 12 for pure liquid extinguishing is advantageous if, for example, a directed jet of liquid is required to reach the source of the fire from a greater distance. In addition, the clearing liquid jet concentrated through the foam tube can be used to achieve a wetting of embers nests hidden deep inside the fire source by means of a targeted jet.
