Flashback Arrestors and Bubblers
Please keep in mind that we
are not the foremost experts on Hydrogen gas.
We are just sharing our experience with you.
Use of both a Flashback Arrestor and Bubbler is probably the safest method.
Flashback Arrestors:
Probably the most important part
of any Hydrogen installation is the Flashback Arrestor. If you don't
have a good one, and I do mean good one then you are destine for trouble.
There are several types of commercial Flashback Arrestors on the market
today available at most any welding supply store. They are the type to
use.
I am fully aware of people making Flashback Arrestor in brass tubes and
packing them full of bronze wool. We did this too, but learned the
hard way that they cannot be trusted for everyday unattended use.
They will work (for a while)... Then they will fail. The bronze
wool eventually burns through and then it is nothing more than a brass tube
in the middle of your feeder line to you intake.
I have heard of some being made out of PVC pipe... The common
sense meter reads ZERO on that idea and I hope that people are not trusting
plastic Flashback Arrestors.
Please only use U/L approved Flashback Arrestors from welding supplies stores!
