  • radiant tube units are only suitable for fire fighting, if you can get close enough to the fire with the tailpipe unit.

  • the nozzle head of the device described in this document has a plurality of outlets, each with a swirling element.
  • This swirling element is set in motion by the pending extinguishing medium pressure and serves the purpose of forming the desired liquid mist. Therefore, the generated liquid mist exits directly on the nozzle head. Effective firefighting by extinguishing agent sufficiently distant from the source of the fire can not be achieved even with the method described in this document or with the device described in this document.

Since the emerging extinguishing agent jet is rotating at the same time, the pressure of the vectoring component of the extinguishing agent jet velocity pointing in the longitudinal direction of the extinguishing agent jet is determined.
  • the extinguishing agent jet emerging from the jet pipe or the jet pipe unit can be set correspondingly to the respective requirements in the case of fire fighting with reference to the two parameters pressure and rotation. It is assumed that the effective throw of the extinguishing agent jet and the speed of rotation can be used to set the distance of the formation of the extinguishing agent mist desired for fire fighting from the jet pipe unit via the pressure of the extinguishing agent supplied to the jet pipe or the jet pipe unit. It is further assumed that the two aforementioned parameters are in a certain context.
