A flame front in a gas pipeline is extinguished by introducing an extinguishing agent at an overpressure at an extinguishing zone of the pipeline. Using an overpressure provides a better and finer atomization of the extinguishing agent, and permits a greater amount of the extinguishing agent to be provided in the extinguishing zone per unit time. In addition, a sealing fluid is introduced at sealing zone of the pipeline. Gas flowing through the pipeline must flow through the sealing fluid in the sealing zone. Preferably, movement of a flame front from one side of the sealing zone to the other side of the sealing zone is prevented or reduced by the sealing fluid.

A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.

A method of custom manufacturing a flame arrestor assembly configured to extinguish a flame propagating therethrough. The method includes creating a customized flame cell using an additive manufacturing technique, which generally includes forming a body and forming one or more channels in the body. The one or more channels define a flow path configured to transfer heat from a flame front propagating through the flow path to the body. The method also includes providing a housing, and securely arranging the flame cell within the housing.

A fire resistant cabinet has a housing delimiting an interior space for accommodating a sanitizer container holding a flammable liquid. The wall of the housing comprises at least one exterior shell part made of at least one material selected from the group consisting of melamine resin, corian or fiber-reinforced concrete.

Provided is a technology of preventing an increase in size of a treatment plant, which may be caused when a safety clearance for the prevention of spread of a fire is set, and restraining an increase in designed fire-extinguishing water usage. A treatment plant for handling a flammable liquid includes: an equipment placement region in which a plurality of equipments configured to handle the flammable fluid are placed, the equipment placement region being divided into four or more firewater supply sections. A plurality of fire-extinguishing water supply facilities are provided to the firewater supply sections, respectively, the fire-extinguishing water supply facilities each being capable of, when a fire occurs in the firewater supply sections, simultaneously supplying fire-extinguishing water to a fire-occurrence section and an adjacent section.

A method of fuel tank inerting includes separating process air into nitrogen-enriched air and oxygen-enriched air with an air separation membrane. A vacuum is applied to the air separation membrane to produce a pressure differential across the air separation membrane. The vacuum is manipulated to vary the pressure differential and vary purity of the nitrogen-enriched air.

Device for the production of selectively configured roll assemblies of expanded aluminium mesh (17) adapted to efficiently fill fuel containers and provide suppression of ignition and combustion of the fuel contained therein, comprising a roll (1) of in expanded aluminium mesh at an inlet of the device, a mechanism (5) for providing tensioning of a mesh web (15) flowing from the inlet to the outlet of the device, a mechanism (6) for forwardly moving mesh web (15), a mechanism (7) for transversely cutting a predetermined portion of mesh web (15), a mechanism (8) that securely folds the edge of the transversely cut end of mesh web (15) and a mechanism (10) wherein a mesh roll assembly (16) is set up onto a disc (12c) that rotates to wind a predetermined number of turns of mesh web (15) around mesh roll assembly (16) and provide an end product of roll assembly of expanded aluminium mesh (17).

The present invention provides systems and methods for preventing fire outbreak and suppressing fire in liquid-fuel activated vehicles.

A packaging unit for one or more of transport or storage of at least one organic peroxide. The packaging unit comprises one or more outer container, such as a transport container and/or a storage container. The packaging unit may also comprise an inner container. The outer container and/or the inner container is filled with the at least one organic peroxide. The packaging unit also comprises one or more extinguishing agent container filled with an extinguishing agent. The extinguishing agent container may be at least one bag and/or at least one bottle. The extinguishing agent container is separately introduced into one or more of a receiving area of the outer container or the inner container. The extinguishing agent container is removable from the outer container. The extinguishing agent container may be detachably connected to or not connected to the outer container, or the extinguishing agent container may be detachably connected to or not connected to the inner container. The extinguishing agent is released from the extinguishing agent container by heat-induced melting, bursting, burning or tearing of the extinguishing agent container.

A cooking system includes an appliance defining a food product volume and a fluid aperture fluidly coupled to the food product volume, a conduit configured to fluidly couple a fire suppressant supply to the fluid aperture, the fire suppressant supply being configured to provide a fire suppressant agent, a flow restrictor positioned along the conduit and configured to restrict a flow rate of the fire suppressant agent through the conduit, and a check valve positioned along the conduit. A portion of the conduit extends between the check valve and the fluid aperture and fluidly couples the check valve to the fluid aperture. The conduit is configured to introduce the fire suppressant agent from the fire suppressant supply into the food product volume of the appliance through the fluid aperture.
