The element is the device that quenches
the flame and the majority of constructions
used incorporate a form of “filter” that
provides small apertures through which the
process gas will flow but will prevent flame
transmission. The flame front is broken down
in the “filter” into smaller flamelets which are
cooled by the large heat capacity of the
