Ignition-quenching systems, apparatuses, and methods

Abstract:

Ignition-quenching systems include an ignition-risk structure that extends from a support structure into a combustible environment and include a porous ignition-quenching cover that substantially covers the ignition-risk structure. The ignition-quenching cover is configured to quench an ignition event triggered by an ignition source associated with the ignition-risk structure. Ignition-quenching covers generally include a porous body. The porous body may include one or more porous elements. Methods according to the present disclosure include installing a porous ignition-quenching cover over an ignition-risk structure to prevent bulk combustion, e.g., of a fuel vapor in a fuel tank, due to an ignition event associated with the ignition-risk structure.
