David,
Let me see if I can say this with a straight face, where are you from? Do you speak English?

Your friend, Colloquial Bob

I think David is saying that his forge uses 3 atmospheric burners made of 3/4" pipe. Not that hard really. :banghead:

Aw Bob ya just gotta remember you don't talk proper english - you talk Texan like I do, so at least I understand ya.:happy:

It's just over 1" OD! Do I have to explain everything? :stomp:

:mstickle:

(I'm actually following all this with interest. I, too, have a ribbon burner on the shelf which I actually used for several years. No one ever told me that they couldn't be atmospheric and it worked surprisingly well. In retrospect, I like it better than my current forge. I think I'll hook up a burner and put a new lining in the old thing.)

Bob - STOP!

Lewis,
Now you’ve done it, I’ve got to try to get a ribbon burner to work as a venturi. It would be good to have a non electric version of the burner. Could you tell me how you were using the burner and what the pluming configuration was like? What size burner is it? did you make it? did you use crayons for port holes? Tell me everything if you wish to live!!!
Bill,
Stuff like that can knock the wind out of you all right. Sometimes it takes awhile to remember where you were headed. My problem is I can’t remember why I’m in the kitchen with the refrigerator door hanging open most of the time.

David,
I suppose all my nonsense and chatter has buried any information you guys can use. The fans are plentiful, abundant go to ebay search for “hydroponic fan” in “all Categories”. I just did, I got 1,156 listings. They call the fans we use “inline fans” they have them from 4” to 12” sizes, I don’t know why plants need filtered air but they seem to use them to blow air through a carbon filter that must be why they require fans that create pressure. Back to the point, they are plentiful and prices seem reasonable, go check it out. They have the speed controllers too, one stop shopping I suppose. Like Rob said ”“don’t get too big” Cheech Martin”. I would try to find a fan that was about a third to a quarter greater maximum CFM than I required. Too large and don’t ask me how to determine what that would be, there are too many variables, experimenting with different manufactures and different sizes with different burners and plumbing systems, would be time and money consuming project. OK I’ll take the responsibility, but I’ll need a little support, everybody send me all your excess time and money and I’ll take care of it…. really, …honestly,…… I mean it. OK back to the point, too large a fan may be a problem if it requires you to lower the RPM past a point where the fan cannot maintain adequate pressure for the CFM you need. This perceived problem may not exist, like I have said before fluid dynamics do not relate to mechanical energy directly in an open system, the pressure may build up at any RPM as the CFM is met, once again too many variables. I really don’t think this is a system that can have a ‘rule of thumb’, without adequately compensating for all the variables. It’s very aggravating to have such a simple thing like a fan be so complicated, the answer may be in experience, we need someone who has done some experimenting, anybody out there?

Looks like I should build my own burner. I had planned on just buying a burner because I figured by the time I located the refractory in a small quantity and spent the time building the burner it would be cheaper to just buy it. Plus I thought it would make it easier to get approval to hook it up to natural gas at some point.

I think I will build my own because I would like to keep the blower cost and noise down and because my forge in its normal configuration is below the minimum size for the Pine Ridge Mini burner. I would like to set the forge up with 2 burners to give me more flexibility, because I usually have it set up 10"x15"x4" but I often have it set up 10"x27"x4" and sometimes higher or the side open. I built my forge using Ralph's plans here http://www.bearhillblacksmith......ilable.htm . I didn't bother building the idle circuit because I am almost always heating more than one bar and I almost never used the idle circuit in my first forge.

I don't know if the Pine Ridge burners are flared, but some large industrial burners use flares on the end. I have made moulds for one of the steel companies here for large burner flares. These were for heating slabs before rolling. They were about 9" dia. However while the flares may be slightly more efficient, we are not running these burners 24/7 and everyone who has seen John's burners seems to rave about how hot they are.
