  • Patent number: 10035033
    Abstract: The present invention relates to a fire-extinguishing composition containing an alcohol/phenol compound and its derivative. The fire-extinguishing composition releases a great quantity of active fire-extinguishing particles by making use of the heat generated from combustion of a pyrotechnic agent. The fire-extinguishing composition containing an alcohol/phenol compound and its derivative in the present invention reacts at a high temperature to generate a great quantity of nanoscale active fire-extinguishing particles, takes reaction with one or more of O-, OH-, H-free radicals necessary for a chain combustion reaction, so as to cut off the chain combustion reaction and take physical and chemical inhibiting effects to jointly achieve a fire extinguishing effect at the same time. Meanwhile, it takes a synergistic interaction effect with pyrotechnic agent to further raise the fire extinguishing efficiency of the fire extinguishing agent and greatly shorten the effective fire extinguishing time.

  • Patent number: 9022133
    Abstract: Water is mixed with fire suppressant polymer in a mixer absent a power source. The mixer receives water through a water inlet with water exhibiting high velocity and associated hydrodynamic force. Such velocity is achieved by locating the water inlet connected to a float or other part of an aircraft so that when the aircraft flies over water with the float dipping into the water, water is driven through the opening and into the water inlet of the mixer. A polymer inlet passes into the mixer. A bend is located downstream of the water inlet and the polymer inlet. The bend exhibits sufficient resistance to fluid flow direction therethrough that the polymer is sheared and thoroughly mixed and activated with the water. A colorant inlet is optionally provided within the mixer and the water and polymer mixture is then discharged into a tank for later utilization at a firefighting location.

  • Patent number: 8701789
    Abstract: The invention relates to a compressed air foam producer, wherein a fire or decontamination specific additive is injected directly into the foam forming flow supplied to the main water flow and/or the main water flow. A mixing pump for the foaming agent draws off an auxiliary and motive water flow, wherein initially the additive and then the foaming agent is injected. The foaming agent-additive-water mixture, which is produced directly on site, is mixed well together and with the main water flow ensuring a fine, uniform distribution of the additives in the compressed air foam. The thus produced compressed air foam ensures optimal, economical and environmentally friendly fire-fighting and decontamination.

  • Patent number: 8662192
    Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomized mist of very small droplet size is mixed with the pressurized gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). The source (5) of the water is pressurized by a feed (30) from the source of pressurized inert gas. The mass flow rate of the water will therefore reduce as the pressure of the gas decays. This tends to maintain the ratio of the mass flow rate of the water to the mass flow rate of the gas constant. This is found to produce and maintain an advantageous distribution of droplet size in the discharged unit.

  • Patent number: 8573317
    Abstract: The method is for continuously producing compressed-air foam, notably for fire fighting or for decontamining, by supplying both compressed air and a mixture of water and at least a foaming agent to a foaming chamber (5) outputting foam to a nozzle (9) via a pipe (8). The mixture of foam agent and water and the compressed air are each continuously supplied to the foaming chamber (5) at a constant pressure and at a constant volume flow rate, e.g. by means of pressure regulators (1, 2) and of flow rate regulators (3, 4). The foam pressure is regulated at the outlet of the foaming chamber (5) for maintaining the foam mixing pressure in the foaming chamber constant, preferably by a self-operating valve (6). The foaming chamber can advantageously be of a static type comprising sieves.

  • Patent number: 8511395
    Abstract: Embodiments of the invention provide a redundant stationary fire fighting system and method for use in a structure coupled to a water supply and a main water pump(s) that generates a water stream. The system includes one or more water flow meters to measure the water stream and generate a water flow signal. The system includes a primary foam proportioning system and a redundant secondary foam proportioning system, each including a foam pump, a motor, a foam flow meter, and a controller. The controller is configured to automatically operate the foam pump based on the water flow signal in order to inject liquid foam concentrate directly into the water stream. The redundant secondary foam proportioning system can be automatically started in case of component failure in the primary foam proportioning system.

  • Patent number: 8460570
    Abstract: Foams and methods of using foams for fighting fires in confined areas (i.e., mine shafts) are provided. In one embodiment, a foam for extinguishing a fire is provided. The foam includes a surfactant; a non-flammable liquid; and an inert gas having a density substantially less than air. Preferably, the density of the foam is substantially less than the density of air. The light foam will allow a basic form of directional control of the foam because the light foam will float towards the ceiling of a cavern or mine shaft. This offers fire fighters several options in extinguishing an underground fire.

  • Publication number: 20130112439
    Abstract: A unique method for suppressing the spread of and extinguishing underground electrical fires in confined areas such as tunnels and conduits. A super absorbent polymer is mixed with water to form a hydrated super absorbent polymer and this admixture is applied to an electrical fire. The admixture has superior fire suppression and extinguishing properties than the fire suppression and extinguishing properties of plain water. The admixture has the ability to cling to the object(s) to which it has been applied and both cool down the object(s) and block the fire from reaching the object(s). The super absorbent polymer and water admixture also encapsulates the noxious and toxic gases produced by electrical fires and prevents the release of these toxic gases into the atmosphere. Finally, the super absorbent polymer and water mixture retains the ash, particulates, and other byproducts of the electrical fire to enable a thorough cleanup.
