Forge break in question

cden said:
Hi Bulb, You might be able to turn your burners down a bit by putting a 'choke' on the air intakes. It's just a plate on a pivot to close down the opening, then you probably can run a lower pressure and turn the temp down without the backing up (maybe?). Nice forge, try it with just the front burner and see what happens.
Take care, Craig

Thanks, I'm going to try one burner tomorrow and see what happens, also the burner holes into the tank are pretty restricted with Kaowool, I'm gonna ream those out and see what happens, I think I'm getting a lot of backpressure there because the holes have gone from 1 1/2" down to about 1". Otherwise that thing heats so fast it's amazing! Before I was try to heat and bend a leaf spring with a Mapp gas torch, took hours! 5 minutes in the forge and it was almost like a wet noodle!
 
Why is there a burner tip? Wouldn't the Kaowool act as a tip if it's supposed to be backed up in the wool about 1" and packed tighty around it? Is it supposed to be flush with the wool or backed in slightly?
 
I would just like to point out that there are quite a few compounds that when ingested through the GI tract or the skin are either non-toxic or have so little toxicity to be negligible. I don't know if zinc and it's oxides are one of those compounds but it's something to think about...
 
Ok bulb, Caution rookie comments, but mine is set up about an inch back from the inside of the forge. To form the inlet in the wool, I 'wet' the inswool with my refractory cement and I pushed a tapered plug into the burner hole. I used a piece of chair leg, the small side about the diameter of the burner flare, and as the refractory set it made a smooth slightly widening outlet into the forge. I really didn't want any loose fibers working free. By burner tip, I think you're refering to the 'flare' that's attatched to the main burner pipe on the business end? My understanding is that it is designed for optimum combustion.
Best of luck, Craig

OK, thanks, I am being careful with everything, wearing a really good respirator, using forge outdoors, washing hands....

Thanks Craig, yes, that's what I meant by tip. I had to break the cement around the inside and then set the burner back about an inch, it had really closed up a lot and I'll have to flare it when I get more refractory cement. Thanks for the help!
