Darren Ellis Gives the Goods

whew, I've posted a lot of continuous messages in this thread...I promise these three will be the last for tonight! :)

Here are pictures of Bruce Bump's forge that is nearly complete!:

Hmmm, I am fairly new posting but have been lurking for over a year, I haven't seen anyone else on here selling or talking forges or getting people the stuff they need to build their own.

Weird.
 
Thanks Darren.

I still need to line the inside with koa wool and ITC-100. The ceiling will be high temp board and the floor will be a couple inches of kitty litter. The blower is too big so its is playing double duty with the air dam on the front door. There is a butterfly valve to adjust the air flow to the fire and the rest goes past the door to keep from burning your hands when forging. Front door is 6x6 and back door is 4x4.

This is what I did with my time while my knee was healing up. What do yaall think?

It needs a Darren Ellis burner too.

were you under a differant name?

anyway there's been a lot under forges done here
:confused:

look here

under build it yourself. ;)

Darren very nice:)
Bruce when's the first coming from it?:)
 
Wow, Darren...I didn't even think about the situtation that I put you in when I asked you to build a complete forge for me. Like a true gentleman, it sounds like you've handled everything with the ut-most courtesy and respect. Like a kid in the candy store, when we started talking...all I could think of was getting what I wanted and didn't do much other thinking from there.

On another note: those pics are fantastic!

I've always had thoughts about a preheater for the forced air forge burner. The concept would be to use some of the wasted heat expelled from the forge to preheat the incoming combustion air with the goal of achieving higher temps. Possible by routing the combustion air through "hot box" section built into the forge side or top. Then direct the preheated air into the combustion area. The fuel might need to be added in a seperate intake with a small amount of ambient air to prevent detonation inside the wind pipe.

The engineer in me is compelled to reclaim some of the wasted energy that is exhausted from opening. I've seen this preheated air concept used on coke fired blast furnaces in foundry applications.

Anyway....just food for thought for all the techno-geek heads that lie awake at night thinking about crazy ideas. (hee hee)

sincerely,
Rob

techno-geek head that must be me :D
Rob now your starting talk of an atmospheric generator oven/Forge
introducing oxygen burnt heat
mine will be with radiant heat for the primary heat
and the spent burned up oxygen heat to
atmospherize the inside.

Actually yes, I was registered under NightStalker6 in Oct 2002 but like I said I was not really posting just lurking.

Bruce, My forge is almost Identical to yours. Dont have an air dam yet but will soon. The only question I have about yours is how long is your burner tube? From the forge wall to the 90` elbow. The reason I bring this up is when I built my about 3 yrs ago I had a burner tube that looked about as long as yours 10". I could never get my forge to perform the way I new it should. I called Devon Thomas he asked the same question. I told him the lenght and he told me it was to short. It need to be a minimum 16" for the gas and air to get a good mix. I changed the lenght and its now the forge from hell.

Michael, It is exactly 10" funny you should ask because the problem Im having is getting a good mix. I may need to lower the Y pipe and inject the fuel at 16". Do you think it matters if there is an elbow in that 16"? Ive heard tell of introducing the fuel directly into the fan housing. That would give about 36" of mixing length. In this design I would need to use a separate blower for the air dam though.
 
Bruce
you could make a metal spiral mixer and put it in the pipe.
kind of like what's in some shower pipes to mix the hot and cold water together
 
I was at Ed Shemps and saw a forge that had its gas line tapped directly into the blower. It worked great. I dont think you could get a better mix. You would have to figure a different configuration for you air dam though. As for Graymakers thought. I tried an air mixer when my pipe was 10" didn't do much of anything. When I extended my pipe to 16" I tried my forge with and without it I couldn't notice a difference.

if you're having the same problem at 10" as at 16" you may have
a different problem than the mix of fuel..the guys with the 10" problem
are getting straightened out with the 16" distance, so that is a mix problem.
you may want to look for something else.
 
Mike Ive heard of the forge at Eds hammer-in. My bum knee kept me home that weekend. My blower is from a Johnson Gas industrial forge from our local high school. It actually has an inlet/outlet on the blower housing. I wonder if that is where the Johnson Gas Company engineered the fuel intake? I can easily try it by plugging the air dam and injecting propane in the blower as a quick test.
