Definitions

  • the invention relates to methods and apparatus for controlling fires and flammable materials.
  • Flammable and otherwise hazardous materials play an important role in the everyday lives of most people. Most people encounter flammable materials, such as gasoline, engine oil, and natural gas, without danger. Because the flammable materials are contained, they typically present no problem for those that are nearby.
  • Fire extinguishing systems play a key role in controlling and extinguishing fires.
  • Numerous materials offer various properties for quenching fires and find applications in various types of fire extinguishing systems, including dry powders, liquids, and foams. Most of these materials directly attack the source of the fire. In particular, the materials are intended to directly cool the fire, deprive the fire of fuel or oxygen, or otherwise interfere with the chemical combustion process that sustains the fire.
  • US 5,304,313 describes chemical concentrates which are introduced into water streams to increase the effectiveness of the water streams in extinguishing fires.
  • US 5,588,493 describes a two-part extinguishant comprising two reactive agents that are combusted by a fire to create an open flame at an elevated temperature which forms a smokescreen or aerosol that can be used to extinguish the fire.
  • US 4,950,410 describes various fire extinguishing compositions that have an aqueous carrier.
  • a fire control system includes an extinguishant having a suppressant and a solid thermal absorbant proximate to the suppressant and configured to absorb thermal mediation.
  • the suppressant is configured to suppress the fire.
  • the thermal absorbant is configured to absorb heat from the fire.
  • the thermal absorbant is configured to absorb thermal radiation from the fire and inhibit reflection of thermal radiation from the suppressant and/or other surfaces back into the fire.
  • the thermal absorbant may be configured to transfer heat into the surface and/or interior of suppressant particles or droplets to promote activation of the suppressant.
  • the extinguishant includes a solid suppressant having a source of colour configured to absorb thermal radiation.
  • the present invention may employ various elements, materials, suppressants, thermal absorbants, heat conductors, neutralizing agents, and the like, which may carry out a variety of functions.
  • the present invention may be practiced in conjunction with any number of applications, environment, hazardous materials, and extinguishants, and the systems described are merely exemplary applications for the invention.
  • the present invention may employ any number of conventional techniques for manufacturing, assembling, dispensation, and the like.
  • a fire control system 100 for controlling and extinguishing fires may be implemented in conjunction with a dispenser 110 containing an extinguishant 112.
  • the dispenser 110 dispenses the extinguishant 112 onto or near the fire.
  • the extinguishant 112 tends to reduce the intensity of the fire and/or extinguish the fire.
  • the dispenser 110 may comprise any suitable system for dispensing the extinguishant 112.
  • the dispenser 110 may also store the extinguishant 112 until the extinguishant 112 is to be deposited on or near a fire.
  • the dispenser 110 may comprise a conventional fire extinguishing system, such as a handheld fire extinguisher, a building fire extinguishing system, a vehicular fire extinguishing system, an industrial fire extinguishing system, and the like.
  • the dispenser 110 comprises a conventional handheld fire extinguisher having a tank 114 for storing the extinguishant 112 and a nozzle 116 for directing the extinguishant 112.
  • the dispenser comprises a vehicular fire panel substantially filled with extinguishant and configured to open and dispense the extinguishant in response to a trigger event, such as an impact.
  • the extinguishant 112 is a material configured to control or extinguish fire in any suitable manner, such as by depriving the fire of heat, oxygen, or fuel, or otherwise disrupting the chemical processes required to sustain the fire.
  • the extinguishant 112 comprises a suppressant and a thermal absorbant.
  • the suppressant is configured to suppress the fire, for example a conventional fire suppressant configured to smother the fire, cut off the fuel supply, or cool the fire below the flammability temperature.
  • the thermal absorbant is suitably configured to absorb thermal radiation from the fire, for example to reduce reflection of thermal radiation by the extinguishant 112 and/or other surfaces.
  • the thermal absorbant can additionally promote activation of the suppressant.
  • the suppressant is configured to reduce the fire, for example via conventional techniques.
  • the suppressant may comprise sodium or potassium bicarbonate, ammonium phosphate, monophosphate, potassium chloride, potassium salt carbon dioxide, HFC-227ea, halon or halotron- I , water, or water mist.
  • the suppressant may comprise, however, any suitable material for suppressing fire.
  • the thermal absorbant is configured to reduce heat, particularly thermal radiation, reflected back into the fire or other heat source by the extinguishant 112 or other surfaces.
  • Fires particularly two-dimensional fires formed on liquid pools of fuel, have multiple mechanisms, including thermal radiation, that sustain the fire as well as dissipate its thermal energy.
  • Thermal radiation tends to contribute to the sustenance and spread of fire.
  • thermal radiation released by the fire transports heat to the liquid pool below to promote vaporization and the introduction of fuel vapor into the reaction zone to sustain the fire. Because radiation is released in all directions, however, energy also radiates away from the fuel and the fire. To maintain sufficient heat to support and sustain the fire, the lost heat must be replaced by heat from the fire.
  • the radiated heat may also contribute to the spread of a fire from its original location.
  • the radiation effects of fire and the role played by thermal radiation are complex, for example due to the complexities of the direction and extent of heat losses, the radiation of heat upon surrounding structures and re-radiations back to the fire, radiation losses and generation within the surrounding hot air itself, and the respective rates of emission, absorption, and reflection from each of the constituents.
  • radiation-based heat deposition on surrounding combustible structures, such as walls and curtains may result in their ignition and sustained fire. This mechanism can result in the spread of the fire to these surrounding structures from the original site of the fire, and can lead to a runaway fire spread condition.
  • Radiation-based heat may also affect the performance of dry chemical fire extinguishing particles when they are introduced into the fire region.
  • Various types of extinguishing particles may function as a sink for the heat released by the fire and cool it below its sustenance temperature.
  • Chemically reactive dry chemicals such as sodium and potassium bicarbonate, also decompose when exposed to heat to release carbon dioxide and metal ions to interrupt the fire reaction chemically as well as smother it. Smaller particles appear to be more effective, possibly because the particles must vaporize rapidly for optimal effectiveness.
  • An extinguishant 112 includes a thermal absorbant to absorb heat transferred by thermal radiation.
  • the thermal absorbant may also be configured to absorb heat transferred by convection and/or conduction.
  • the thermal absorbant is suitably configured to modify the outer surface and/or interior of the suppressant to absorb more thermal radiation. Consequently, less heat tends to be reflected back to maintain the fire. Further, more heat is transported into the suppressant so that heat-reactive suppressants may decompose faster to release their chemical ions and decomposition products to chemically interrupt the fire.
  • thermal absorbant that is not in the immediate vicinity of the fire may extract additional heat from the fire and potentially inhibit ignition of surrounding combustible materials by reducing the transmission of thermal radiation to the surrounding area.
  • the thermal absorbant provides color in conjunction with the suppressant to provide a thermally absorptive surface, such as by at least partially changing the surface to flat black and/or providing a thermal conductor into the interior of the suppressant particle. Absorptive surfaces tend to absorb instead of reflect heat. The thermal absorbant tends to promote extraction of heat from the environment and/or decomposition of the suppressant. The use of the thermal absorbant also facilitates the use of larger suppressant particles to maintain favorable throw characteristics. The thermal absorbant inhibits transport and/or reflection of heat to fuel sources, and causes the extinguishant 112 to break down in areas farther from the center of the reaction zone to create a more concentrated cloud of metal ions and inert gas molecules induced into the fire.
  • the thermal absorbant may be configured in any suitable manner to reduce the reflection of heat back into the fire, transmission of heat to other combustibles, and/or promote activation of the suppressant.
  • the thermal absorbant is configured to absorb heat, such as heat transferred via thermal convection and/or conduction, in addition to radiation.
  • the thermal absorbant may be configured in any suitable manner to absorb heat, such as by providing a thermally absorptive color or other characteristics to the extinguishant 112.
  • the thermal absorbant may provide an appropriate color to the extinguishant 112 that tends to absorb thermal energy instead of reflecting thermal energy.
  • the thermal absorbant may be configured to absorb as many radiation wavelengths as possible, such as a flat black color, or may be configured to absorb particular wavelengths or temperatures, such as wavelengths corresponding to carbon-based emission spectra or wavelengths associated with particular flammable materials found in a certain environment.
  • the thermal absorbent may exhibit any other effective or desired color, such as various shades of gray, one or more colors mixed within the thermal absorbant, or other configurations.
  • the thermal absorbant may be selected according to any suitable criteria, such as cost, durability, effectiveness in absorbing selected relevant wavelengths, effectiveness in coloring the extinguishant 112, flow performance, extinguishing performance, and the like.
  • the thermal absorbant may be selected according to other criteria as well, such as other fire extinguishing capabilities, improved handling, lower toxicity, easier cleanup, or other relevant criteria.
  • the thermal absorbant may operate in conjunction with the suppressant in any suitable manner.
  • the thermal absorbent is suitably disposed proximate to the suppressant, such as mixed with the suppressant, attached to the suppressant, or integrated into the suppressant
  • the extinguishant 112 comprises a gaseous, or liquefied compressed gas suppressant 210 mixed with a solid thermal absorbant 212.
  • the suppressant 210 and the solid thermal absorbant 212 may be pre-mixed or mixed upon dispensation.
  • the thermal absorbant 212 may increase the thermal absorption of the extinguishant 112 in any suitable manner, such as by darkening the gaseous or liquid suppressant 210 or providing intermixed particles having darker surfaces for absorbing thermal radiation.
  • the thermal absorbant 212 may comprise a dye, a plurality of small particles, or other coloring to increase the thermal absorption of the extinguishant 112.
  • the combination of the dark, such as flat black, thermal absorbant 212 with the suppressant 210 tends to reduce the reflectivity of the extinguishant 112.
  • a thermal absorbant 212 may operate as a dye or other coloration to make the overall extinguishant 112 a selected, thermally absorptive material. If a solid suppressant 210 is mixed with a solid thermal absorbant 212, such as a plurality of small black particles or beads, the overall reflectivity of the extinguishant 112 is reduced.
  • the suppressant 212 is a solid or semi-solid material and the thermal absorbant 212 may be attached to the suppressant 210.
  • the suppressant 212 may comprise any suitable material for suppressing fire or other hazard, such as a conventional dry chemical file suppressant.
  • the thermal absorbant 212 may be any suitable material, such as a material that is flat black or has other desired colors or characteristics, to reduce the reflection of heat from the suppressant 210 or other surfaces and/or absorb heat and transfer it to the suppressant 210.
  • the thermal absorbant 212 may be positioned on the surface of some or all of the suppressant 210 particles, such as in the form of a substantially uniform coating over the exterior surface of the suppressant 210.
  • the thermal absorbant 212 may comprise a surface coloration on the suppressant 210. Treating only the surface of the suppressant 210 particle tends to minimize the amount of thermal absorbant 212 required, and maintains the increased heat absorption until the coating or modified surface evaporates during melting.
  • the thermal absorbant 212 may be applied to the suppressant 210 particles in any suitable manner.
  • the thermal absorbent 212 may be added using a dry process, such as by applying a dye or other coloration to the suppressant 210 particles. Any appropriate technique may be used to apply the thermal absorbant 212 to the suppressant 210, however, such as deposition, spray drying, electrostatic techniques, or the like.
  • the suppressant 210 particles may also be partially covered by the thermal absorbent 212.
  • the partial covering of the suppressant 210 particles may be implemented in any suitable manner, such as by placing the suppressant 210 particles in contact with a thermal absorbant 212 that leaves a residue on the surface of the thermal suppressant 210 particles, for example activated charcoal particles or an appropriately colored geL
  • the suppressant 210 particles may be mixed with charcoal particles 410 and circulated to optimize the residue 412 delivered by the charcoal or other thermal absorbant 212.
  • the thermal absorbant 212 is permeated or embedded into the suppressant 210.
  • the thermal absorbent 212 suitably comprises a material which may permeate into suppressant 210, such as a material added to the suppressant during or after fabrication.
  • the thermal absorbant 212 may be integrated into the suppressant 210, such as by forming the suppressant 210 from a thermally absorptive material using wet treatment, such as by dissolving the suppressant 210 particles with the dye added and forming the desired extinguishant particles by later grinding and treatment.
  • the thermal absorbant 212 may comprise particles formed or embedded in or attached to the suppressant 210, or vice versa.
  • the thermal absorbant 212 may comprise any suitable heat absorbant, such as a material configured to absorb thermal radiation and/or transfer heat onto the surface of and/or into the interior of the suppressant 210.
  • particles of iron oxide 610 or other thermal absorbent may be attached to the surface of the suppressant 210 particles.
  • the iron oxide particles 610 are suitably smaller than the suppressant 210 particles and may be adhered to or embedded in the suppressant 210 particles in any suitable manner.
  • Iron oxide is typically an effective thermal radiation absorbant, and may conduct heat to the suppressant surface.
  • Iron oxide is generally considered inert in hot environments, but if transported to a flame interior or other hot area by a suppressant 210 particle, the iron oxide particles 610 may decompose and deliver highly-effective iron ions to inhibit the fire chemically.
  • the thermal absorbant 212 may also serve other functions as well as enhancing the thermal absorption of the extinguishant 112.
  • the suppressant 210 may comprise a heat-activated suppressant, such as sodium bicarbonate, and the thermal absorbant 212 may be configured to promote activation of the suppressant 210.
  • the thermal absorbant 212 may be attached to or integrated with the suppressant 210.
  • the thermal absorbant 212 is suitably configured to conduct or produce heat into the suppressant 210 to speed the activation of the suppressant 210.
  • the thermal absorbant 212 may comprise a material that reacts exothermically when exposed to sufficiently high temperatures, such as activated charcoal.
  • thermal absorbant When exposed to a fire, thermal absorbant may generate additional heat locally to promote activation of the suppressant 210, thus tending to extinguish the fire faster.
  • the thermal absorbant 212 may operate as a supplementary suppressant, for example by tending to deprive the fire of oxygen or fuel.
  • the thermal absorbant 212 may comprise a thermally absorptive material having a suppressant material.
  • the thermal absorbant 212 may comprise a material that is activated by exposure to heat to become a suppressant 210.
  • the thermal absorbant 212 comprises a material embedded in the suppressant 210 to promote activation of the suppressant 210, and as the suppressant 210 is activated and the thermal absorbant 212 heats up, the thermal absorbant 212 changes into a material having suppressant properties.
  • the extinguishant 112 may comprise a sodium bicarbonate suppressant 210 having thermal absorbant 212 particles of iron oxide embedded in the suppressant particles.
  • the thermal absorbant 212 particles transfer heat to the suppressant 210 particles, including the interior of the suppressant 210 particles to promote activation of the suppressant 210.
  • the thermal absorbant 212 particles react to the heat by generating iron ions, which provide added suppressant properties for suppressing the fire.
  • the extinguishant 112 may also be configured to reduce or neutralize flammable components.
  • the thermal absorbant 212 may comprise a porous material, such as activated charcoal, that tends to absorb flammable gases.
  • the thermal absorbant 212, the suppressant 210, or an added material to the extinguishant 112 may comprise a material that tends to neutralize or reduce the flammability of one of more flammable components.
  • the extinguishant 112 in response to detection of a fire, for example visually or automatically through a fire detection system, the extinguishant 112 is dispensed onto or near a fire or fire hazard via the dispenser 110.
  • the suppressant 210 tends to reduce the fire, such as by depriving the fire of fuel and/or oxygen.
  • the thermal absorbant 212 tends to absorb heat from the fire.
  • the thermal absorbant 212 tends to reduce reflection of thermal radiation back into the fire and/or to other surfaces. Extinguishant 112 that fails to contact the fire may nonetheless absorb heat and reduce reflection or transfer of heat from the extinguishant 112 and other surfaces, tending to inhibit spread or growth of the fire.
  • the thermal absorbant 212 may assist in the activation of the suppressant 210. As the extinguishant 112 approaches the fire, the suppressant 210 and the thermal absorbant 212 absorb heat, which tends to activate the suppressant 210. The thermal absorbant 212 absorbs heat faster than the suppressant 210, which is transferred to the suppressant 210, promoting the faster activation of the suppressant 210. Activation of the suppressant 210 may be further enhanced for suppressants 210 having thermal absorbants 212 penetrating the outer surface of the suppressant 210, such that the thermal absorbant 212 may convey heat directly to the interior of the suppressant 210.
  • the thermal absorbant 212 may convert into a supplementary suppressant. As the thermal absorbant 212 absorbs heat from the fire, the thermal absorbant 212 may change into a material having suppressant properties. The thermal absorbant 212 may also absorb and/or neutralize flammable materials in the environment, such as by absorbing flammable gases into pores in the thermal absorbant.
