An exemplary fire suppression system includes a sprinkler nozzle. At least one conduit is connected to the nozzle for delivering a fire suppression fluid to the nozzle. The conduit and the nozzle establish a discharge path. A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit. A gas source provides pressurized gas to the pump for driving the pump. The gas source also provides gas to the discharge path for achieving a desired discharge of the fluid from the nozzle. A controller selectively controls at least one of (i) the gas provided to the pump, which controls the fluid pressure in the conduit, or (ii) the gas provided to the nozzle or the conduit, which controls the gas pressure delivered to the nozzle.

A fire suppression system includes a Coolant Infusion Spray Nozzle (CISN) and a Coolant Introduction Adapter Cap (CIAC). The CISN includes a water inlet and a coolant inlet. The CISN also includes a coolant infuser with infusion aperture(s) for injecting coolant into the water as it is bypassing the coolant infuser. This CISN generates a fire suppressing stream of coolant and water mixture. The CIAC supplies water and coolant to the CISN. The CIAC is coupled to a water source, and is also coupled to the CISN via hoses. The CIAC can includes an elbow for directing coolant toward the CISN.

A method as well as a liquid mixing system provide a liquid-foam mixture by mixing water with at least one additive. The liquid mixing system includes a water pressure source, an additive reservoir unit, an air compressor unit with a compressor and a drive device, a first and second mixing device, a discharging unit, and multiple different line networks for the respective media. The drive device is formed by a water engine or a water turbine, the water inlet of which is line-connected to the water pressure source.

A mobile firefighting system includes a water cannon enabled for spraying slush on or near a fire. The slush includes solid material (e.g., ice, solid fire retardant) that is projected farther than a liquid could be projected using high pressure. The slush has enhanced fire suppression and fire protection characteristics compared to a liquid. Multiple tanks add enhanced slush chilling capability (e.g., through sequenced chilling) and provide redundant backup systems. A mobile cannon includes multiple reducing nozzles that can be aimed by a rotating base and hydraulic cylinder (for raising and lowering). Continuous tracks and winches contribute to all-terrain capabilities.

Invention relates to fire suppressing gas generating devices, especially to a gas outflow management in the fire suppressing gas generating devices. A fire suppressing gas generating device comprising a cylindrical housing (1) having at least one discharge opening (13); a plurality of gas generating grains (2); an ignitor (5) associated with the gas generating grain (2) for ignition of said gas generating grain (2); a filter (6) encompassing the plurality of the gas generating grains (2); and at least one gas discharge channel (7) connected to the discharge opening (13). The gas discharge channel (7) further comprises at least two nozzles (17) opposed to each other creating thrust neutrality of discharged gas.

A fire-extinguishing device for a vehicle battery includes: a gas discharge part installed in a battery pack and configured to discharge gas inside the battery pack; a gas path part configured to permit the flow of gas generated in the battery pack and discharged through the gas discharge part in the event of a fire; a catalytic converter installed in the gas path part and configured to convert carbon monoxide in gas flowing through the gas path part into carbon dioxide; and a fire-extinguishing agent tank configured to store a fire-extinguishing agent and to be connected to the gas path part. The fire-extinguishing agent tank allows the carbon dioxide converted by the catalytic converter to flow thereinto. The fire-extinguishing device for a vehicle battery further includes a fire-extinguishing agent supply path part connecting the fire-extinguishing agent tank to the battery pack.

A fire suppressant system is a device that uses steam/super-heated water to suppress and put out fires rather than the traditional water method. The invention uses steam/super-heated water under high pressure to blow out and suppress the fire. The wet pressurized steam/super-heated water “blows out” the fire and the pressure removes (displaces) the oxygen and spark needed for the fire to continue burning. The wet steam/super-heated water works much like water to suppress and put out the fire but the additional benefits of the pressure help to reduce the fuel (air and spark) for the fire as well.

A fire-suppression technology system has a tank with outlet and inlet orifices. A reservoir has a dispensing orifice. The tank receives water. The reservoir receives a quantity of powder adapted to be converted to a fire-suppressing fluid when mixed with water. A pump operatively couples the tank and the reservoir. A hose is operatively coupled to the pump. A spool is supports the hose. A primary path of travel constitutes a closed loop path between the tank and the pump and the reservoir to create a fire-suppressing fluid. A secondary path of travel constitutes an open path for dispensing the fire-suppressing fluid from the tank and the pump toward a region to be controlled.

Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.
