Dragon's Breath - Normal?

8 posts in this topic

So I just bought my first commercially made forge - a two burner unit from Diamondback. 

I did notice that it has about 6 inches of clear bluish dragon's breath coming out each end. I tried to take a photo, but it is pretty hard to see. 

Basic question, is this normal? Is there anything I should be doing to reduce that from occurring or is it just the way that forges operates?

Thanks!

What was the regulator set to?

What did the people who sold it to you say when you asked them?

I have a similar` forge although it is not from Diamondback and it only has one burner.   Some dragons breath is normal although my forge has the same characteristic, too much flames coming out the ends of the forge when the burner is turned up to a good heat.   Mine has a great 1" dia. burner so maybe I should not be complaining.  My forge has no castable refractory lining nor did it have rigidizer on the ceramic insulation, or an IR reflective coating, just barebones on the inside, and it looks like yours is the same.   I am going to guess that yours is working as it should.  How do you regulate the heat, do you have an adjustable regulator or a needle valve, can you turn the burners down to a pleasant idle?  One thing you want to do is build a shelf on each end of the forge to help hold material that is being heated, and you might think seriously about installing a door at each end.   The door does not have to be fancy, I use sliding fire bricks.   I have had mine over a year and am slowing building a new two burner forge.

To me, Dragon's breath is any kind of exit flame coming out of a forge or casting furnace. However, there can be several different reasons for such flames. When it comes to blue exit flames, they are do to incomplete combustion within the forge, and are full of carbon monoxide; not cool; not acceptable!

BTW, I can't see any dragon'a breath in this photo; what I see is a forge that is wide open along one of its side, and looks pretty well heated up inspite of that error.

The maker of this forge specifically says the ends should remain open. 

I created a video so you can see and hear it a bit better. Interestingly, the dragons breath on the backside is more orange than on the other side?

Here is a link to the video: https://youtu.be/dDiG_U5ybT4

I looked at the video; the dragon's breath looks like a lot, but how far down are the two burners turned?
