A method of custom manufacturing a flame arrestor includes providing a housing having an interior surface and an exterior surface where the exterior surface of the housing is shaped to fit within a fluid passageway. The method includes forming, using an additive manufacturing technique, a three-dimensional lattice structure by depositing a first material onto the interior surface of the housing in a predetermined pattern. The lattice structure includes a plurality of connected lattice members forming channels extending from a first end to a second end of the three-dimensional lattice structure. An element of a second material is provided adjacent to the three-dimensional lattice structure. The second material is different than the first material and the element is configured to draw heat away from fluid flowing through the plurality of channels.

A firebreak device configured to arrest a flow of medical gas capable of combustion or of supporting combustion, said device comprising: a housing having a body portion, an inlet and an outlet, said inlet and outlet being linked by a conduit; a valve assembly located within said body portion, said valve assembly being movable between an open position, in which gas can flow between said inlet and outlet along said conduit, and a closed position in which gas flow between said inlet and said outlet is arrested; a biasing assembly (340) arranged within said body portion to move said valve assembly into said closed position; and a heat activatable stop (350) located between said biasing assembly and said outlet to hold said valve assembly in said open position against said biasing assembly, and adapted to release said valve assembly to allow said biasing assembly to move said valve assembly to said closed position at an activation temperature, to close flow of gas through the device if said heat activatable stop is activated, wherein: said heat activatable stop is arranged to prevent obstruction of said flow of gas adjacent an inner surface of said device.

The invention relates to an ejector nozzle having a liquid-carrying duct and a gas-carrying duct. The gas-carrying duct opens into the liquid-carrying duct upstream of an outlet opening. The insert acting as a flame arrester is positioned in the gas-carrying duct. The insert is configured in such a way that no gas can flow around the insert. The invention furthermore relates to use of the ejector nozzle in a jet loop reactor.

Flame arrestors and methods of making flame arrestors are described herein. An example flame arrestor includes a cylindrical body. The body includes a first end and a second end opposite the first end. The first end of the body has an end surface. The body also includes a recess formed in the end surface of the first end. The recess is defined by a recessed surface extending inward from the end surface toward the second end. The body further includes a set of channels formed through the body between the first and second ends. The channels extend through the recessed surface.
