Definitions

  • the invention relates to a flame resistive ventilation device intended as a fire blocking device, in particular for blocking flames, which can be transferred through ventilation grates and similar apertures with air transfer ("ventilation devices").
  • ventilation devices air transfer devices
  • the term "firebiocking ventilation device” is directed to a passive element, open for air transfer, which prevents the spreading of fire by penetration of flames, heat conduction, convection or radiation.
  • the invention also relates to a method for fire blocking in a ventilation device.
  • Open flame arresters are known which function as heat sink for explosive combustion or shortlived fireballs. They are arranged open, so that air transfers, but not flames. They are often made of steel, either as perforated plates or mesh or as steel strip bodies pressed together, and similar.
  • the function of arresting deflagration combustion first became known as Davy's net in 1815, used by Sir Humphrey Davy, and such elements have been used for different industrial purposes, such as for engine block ventilation and in gas production facilities, as explosion flame shields for personal safety offshore and similar.
  • Building fires are in some instances transferred by flames spreading through openings and channels containing or being adjacent to combustible elements or materials.
  • An example of such a risk in buildings are the inlets to ventilated, non-heated roofs (voids) or attics, where flames on the outside of a wall or from a window, can spread through ventilators in eaves and into combustible structures in attics.
  • Such areas are not easy accessible, and fires that take hold in such areas often result in dramatic consequences.
  • a fire blocking device which comprises a grille body with a plurality of openings permitting an air flow therethrough, said body being formed of, or coated with an intumescent material and a thermally conductive metal mesh also permitting an air flow, wherein the metal mesh has a capacity for heat storage and the intumescent material swells when exposed to sufficient heat to seal the openings.
  • this previous fire blocking device had limitations in more respects, e.g. for making a cavity fire barrier and for providing a two way ventilation device.
  • the main object of the present invention is to create passive and instantly acting fireblocking devices, being an improvement to the prior art, including the ventilation device of the parent application.
  • the ventilation device should be adaptable for use as a cavity flame barrier device.
  • the invention is directed to a novel method for blocking fire in a ventilation device arranged in building or similar structure, comprising:
  • the invention also comprises a flame and fire resistant ventilation device, comprising:
  • a mesh element having a plurality of vent openings dimensioned to quench transient flames, - a swelling element formed of or coated with an intumescent material, to permanently 30 seal the ventilation device during sustained fire exposure;
  • the fireblocking devices according to the invention will instantly prevent flame spreading while not blocking air passage in the normal state. At the same time, birds, insects, leaves and embers are kept out. The air velocity may be reduced in regard to fully open venting gaps between soffit boards, but this may be an advantage, as new research indicates that former regulations were exaggerated and less energy efficient.
  • the fireblocking devices according to the invention can be produced at low cost with inexpensive materials. Installation of the fireblocking device or post-installation with replacement of existing ventilating grilles, respectively, can take place without any particular training and in an easy manner. Furthermore, it is possible to make the fireblocking device according to the invention maintenance-free.
  • Examples of applications of the invention are vents in walls, bulkheads, tanks, ducts, air duct terminals, openings for natural ventilation, in processing plants, vented facade exteriors, vented fire blankets, open fire protective curtains or open protective screens against explosions.
  • a fireblocking device can be used in various applications. It is suitable for buildings, especially in connection with vented attics and as ventilating grilles for ducts and voids that contains combustible material, or which can transfer flames to other combustible structures. Additional fireblocking devices according to the invention can be arranged after one another in a duct or in a transition area. Smoke blocking can easily be obtained by integrating a smoke blocking device or adding one in series as prescribed for smoke and fire dampers by current regulation (ICC in USA).
