A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

A fuel tank inerting system is disclosed, comprising a fuel tank and an electrochemical cell comprising a cathode and an anode separated by a separator comprising an anion transfer medium. A cathode fluid flow path is in operative fluid communication with a catalyst at the cathode between a cathode fluid flow path inlet and a cathode fluid flow path outlet. An anode fluid flow path is in operative fluid communication with a catalyst at the anode, and includes an anode fluid flow path outlet. An electrical connected to a power source is arranged to provide a voltage difference between the anode and the cathode. An air source is in operative fluid communication with either or both of the cathode flow path inlet and the anode flow path inlet. An inert gas flow path is in operative fluid communication with the cathode flow path outlet and the fuel tank.

A fuel tank inerting system includes an air separation module with an oxygen permeable membrane and a variable vacuum source in fluid communication with the air separation module. The variable vacuum source provides an adjustable vacuum to the permeate side of the oxygen permeable membrane in the air separation module, driving production of inert gas for fuel tank inerting or fire suppression.

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.

Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.
