Gas burner noise?

Recommended Posts

I'm using my improvised gas forge with only one burner for the last few weeks, still get more than enough heat and used a lot less gas.

I've learned enough from this forge to attempt another, or just modify the existing one considerably.

 

Part of the plan is definitely another burner.  

 

My neighbour and I considered a forging demo at a public event 2nd November, part of the reason we decided against it is my forge is the only option, but it sounds like a jet taking off.

We would have to shout to be heard, and we would be a disturbance for the rest of the event.

 

My only other experience is a big forge with 2 burners that's even worse........and youtube videos.....

 

So my question is basically what can I do to reduce the noise of the new burner? Will a longer burner be quieter? 

 

......Or are they just using good microphones and/or PA systems in these videos?

From my experience gas forges just sound like a jet engine idling.

The best option for quieting down a gas forge is to use a multi-port burner outlet (popularly called a ribbon burner).  While these are easier to design for forced air/gas forges they certainly can be used with naturally aspirated burners as well.  Careful consideration to matching forge volume and configuration, burner size and multiport outlet are required.  I believe that Dudley Giberson at Joppa Glassworks has a packaged design that is worth looking at.

 

Note that they are still not quiet, but certainly quieter than a typical burner flare (or even worse a post mix burner system like the old Eclipse burners).

Mine sounds more like take-off than idle.

 

Pretty sure the short pipes are a part of my problem, but from your answers I conclude the youtube dudes have good mics....those fluffy ones :lol:

 

I can get a few real fire bricks to build a replacement.  Think I should take one day in the week and dedicate that to tool building.....
