Definitions

  • the invention relates to a method for fighting fires in closed rooms and buildings where by introducing at least one inert gas, the oxygen content the atmosphere in the area of the fire under one necessary to maintain the fire Value is lowered. It also affects one Device for performing such a method.
  • halons were the preferred extinguishing agent for fighting fires in closed rooms where water jets, foam or powder cannot or must not be used.
  • a method of the type mentioned at the outset was proposed as an alternative, in which an inert gas is blown into the room affected by a fire, in order in this way to reduce the oxygen content of the atmosphere therein to that required for the fire to continue Press value of about 12 to 15 percent.
  • Propellants that develop high nitrogen-containing exhaust gases during their reaction have already been considered as possible inert gas generators. However, in addition to nitrogen (N 2 ), these exhaust gases usually also contain carbon dioxide (CO 2 ) in a proportion of up to 20%.
  • solid propellants based on sodium azide have been proposed, such as those used in miniaturized form in vehicle airbags. Although these have the advantage that they provide almost pure nitrogen as the reaction product, their use on a larger scale is contrary to the toxicity of the starting products. In addition, when they burn, there are corrosive and health-damaging dusts that have to be intercepted or neutralized by special measures.
  • Another object of the invention is a device to provide the simplest possible and effective way of performing the invention Procedure allows.
  • the invention achieves the first object by a method in which a reaction of ammonia (NH 3 ) with ambient air generates nitrogen (N 2 ) and water vapor (H 2 O) and is supplied to the source of the fire as a quenching gas mixture.
  • NH 3 ammonia
  • APU auxiliary power unit
  • Similar small gas turbine plants are also used in stationary operation as small power plants, but where they are also operated with hydrocarbons as fuels.
  • the invention therefore has the advantage that it is based on the use of such a system, which largely corresponds to the state of the art, on the one hand on tried and tested and reliable and also immediately available components, and on the other hand, through the use of ammonia as the fuel provided for this system delivers absolutely CO 2 -free exhaust gas, which is also free of dust particles. It can be operated for long periods of time by adding ammonia that can be stored easily and in large quantities, and can be switched off and started again as often as required. In addition, their operation can be maintained by simply refilling ammonia or their operational waiting state can be guaranteed.
  • the device according to the invention can be both stationary operated and connected to a fire extinguishing pipe network as well as in the form of a mobile unit for one autonomous operation can be provided. Your start can just as with kerosene-operated systems, electro thermally or via a pilot flame. Finally has the device according to the invention in its preferred embodiment via a sensor-controlled Temperature control of both the working gas before entry into the turbine as well as the inert gas before Feed into the fire extinguishing pipe network. This is about realized a water injection.
  • the figure shows a schematic representation of the Construction of a device for producing carbon dioxide-free Inert gas for fire fighting purposes. Of the The structure of this device corresponds essentially that of a small gas turbine plant, such as Auxiliary power generation system or APU in aircraft is used.
  • ambient air is drawn in by a compressor (1) and, in a compressed state, is pressed into a combustion chamber (2).
  • ammonia (NH 3 ) is supplied via an injection valve (3), which is conveyed from a storage container (5) by means of a pump (4) and brought to the pressure prevailing in the combustion chamber (2).
  • This water is over a second pump (6) from a second reservoir (7) promoted and dosed.
  • the two pumps (4) and (6) are driven by a gear (8) on a common shaft (9) with the compressor (1) and is arranged with a turbine (10).
  • Latter is caused by the exhaust gas generated in the combustion chamber (2) driven and feeds this into a mixing chamber (11) where it is made by a valve (12) Water injection on fire fighting appropriate temperature cooled and in a Fire extinguishing pipe network (13) is fed.
