Supercharging a natural gas BG14 burner

[calgary222]

"just looking for a cheap wall-wort that I can strip and attach to the leads on this fan to get it running."

That's exactly what I did... I don't throw stuff out so I had a pile to choose from.

I bought these twice, a pair for my stand and a pair for my keezer:

I'd love to see pics and/or video of the air injection on your stand! I've been using the fans on my HLT and BK for over two years now and it makes such a HUGE difference.

I'll try and get a pic tonight - "but it ain't pretty" - all I did was take a 3" piece of copper pipe and flatten one end enough to jam into the bg14 venturie, electrical tape the other end to the fan and then ran the wires from I think a 9v wall wort... I noticed a big improvement in the quality of the flame, but never did a scientific time to temperature test.

Edit:

Pics here, pic two shows the simple electrical tower, each socket has a switch in the panel, both fans run together - not pretty, works well. Note that I lifted my kettles by the 1" to improve airflow.

Yes, I use the same blower you linked. I've since added a second one for my HLT tank. They work pretty good. I tried using a variable speed controller, but the fan didn't respond well with it. I use a strip of duct tape about 3/16" wide that is across the duct tube to lessen the air flow just a little.

I have a stainless tube that is ducted up to my burner so that I can keep the blower motor under my stand with the rest of the wiring stuff. It makes for a really clean installation.

I have thought about drilling out the NG orifice to see if I could get even more gas flow. It would likely no longer work without the blower attached as it would be way too rich, but that's not an issue as I always use the blower.

bsent - please update here with any other tests/findings you come up with.

I personally am very happy with the performance I'm getting now using the air assist. It is nearly equivalent to the wok/jet style burners I previously used, but is silent instead of the incessant load jet engine noise. Also, putting the blowers under the rig also help minimize any sound from them.

Jon, Amazing Rig! I'm also a fan of the full stainless. I built mine weld-less out of a SS Kitchen Table.

Where did you purchase the SS Duct from?

I'd like to do the same for my rig. I have the same squirrel cage blowers and BG14s. Except I've drilled the orifice to get more gas out.

Thanks

The SS tube that I run the air into was custom made by Brewers Hardware. Give them a spec and they'll make it!

I like to hide wiring, valves, etc. under the diamond plate shelf, so I wanted to do it that way for looks. The pics above from Calgary222 looks to be a pretty simple setup too. One additional benefit of having the fans under my shelf is that it helps to cut the fan noise (not loud by any stretch, but helps to keep it pretty quiet).
