CAT to LENRapproach 8 wmv

Hi all

This a test i made to prevent the flashback to come back along the seringue’s needle and burn and destroy it. (see my previous video ).

I have burned a lot of needles, because when i put the needle too near the hot point. the flashback occures inside the needle and burn it up to the flashbackarrestor and can damage it, that’s why i have 2 arrestors in serie.

But the result was good as you can see , no burning of the needle.

BUT BUT , after the video i cut the small piece of substrate and i descover that in the middle part of the piece. the ceramic was partially melt. So probably after some times , the “sun ” occurs and melt the ceramic.

So not so good and back to bench

Good luck at all
