Abstract
A method, system, and apparatus for flame arresting are provided. In an embodiment, a flame arrestor includes a quenching element disposed within a conduit. The flame arrestor also includes a cooling system in thermal contact with the quenching system. The cooling system cools the quenching element during operation of the cooling system.
Claims20
A flame arrestor, comprising:
- a quenching element disposed within a container for containing a combustible fluid at a pressure;
- and
- a cryogenic cooling system in thermal contact with the quenching element, wherein the cryogenic cooling system comprises a hollow component filled with a cooling fluid comprising one of liquid nitrogen and liquid helium, the hollow component comprising a cooling element conduit, wherein the cooling element conduit provides the cooling fluid to the cryogenic cooling system such that the cooling fluid flows through the cryogenic cooling system to extract heat from the quenching element, wherein the cryogenic cooling system cools the quenching element to a cryogenic temperature and maintains the quenching element at the cryogenic temperature during operation of the cryogenic cooling system;
- wherein the quenching element comprises a distance between opposing walls of the quenching element, the distance being smaller than a quenching distance of the combustible fluid when the quenching element is at the cryogenic temperature.
1 more element
A flame arrestor, comprising:
- a fluid transport pipe for transporting a combustible fluid from a first point to a second point at a pressure;
- a quenching element disposed within an inner volume of the fluid transport pipe, the quenching element comprising a flame arresting material;
- and
- a cooling element in thermal contact with the quenching element to cool the quenching element to a cryogenic temperature and maintain the quenching element at the cryogenic temperature during operation of the flame arrestor;
- wherein the quenching element comprises a distance between opposing walls of the quenching element, the distance being smaller than a quenching distance of the combustible fluid when the quenching element is at the cryogenic temperature;
- and
- wherein the cooling element comprises a hollow component filled with a cooling fluid comprising one of liquid nitrogen and liquid helium, the hollow component comprising a cooling element conduit, wherein the cooling element conduit provides the cooling fluid to the cooling element such that the cooling fluid flows through the cooling element to extract heat from the quenching element and the cooling element conduit provides for the cooling fluid to flow away from the quenching element through a heat exchanger to dissipate heat removed from the quenching element.
4 more elements
A vehicle, comprising:
- a vehicle frame structure;
- a fluid housing conduit within the vehicle frame structure, the fluid housing conduit configured to be at least partially filled with a combustible fluid at a pressure;
- a quenching element disposed within an inner chamber of the fluid housing conduit, the quenching element comprising a flame arresting material;
- and
- a cooling element thermally coupled to the quenching element to cool the quenching element to a cryogenic temperature and maintain the cryogenic temperature of the quenching element during operation of the vehicle;
- wherein the quenching element comprises a distance between opposing walls of the quenching element, the distance being smaller than a quenching distance of the combustible fluid when the quenching element is at the cryogenic temperature;
- and
- wherein the cooling element comprises a hollow component filled with a cooling fluid comprising one of liquid nitrogen and liquid helium, the hollow component comprising a cooling element conduit, wherein the cooling element conduit provides the cooling fluid to the cooling element such that the cooling fluid flows through the cooling element to extract heat from the quenching element and the cooling element conduit provides for the cooling fluid to flow away from the quenching element through a heat exchanger to dissipate heat removed from the quenching element.
