  1. Your nearest propane supplier can answer all your questions, including federal and local laws regarding handling, storage. and legal use of this fuel. Or you can just wait until all their penalties come do. One thing is sure; if you don't know the laws you have no chance not to avoid the big grin on an insurance adjusters face when you tells you that the bill is all yours, because you voided the terms of your policy
  2. What I seem to be seeing is sharp clean burner flames. You may work on the icing a little more--or not--but you've plenty of cake
  3. Congratulations on making a very hot flame with your very first try. You will need #316 stainless steel. or frefractory for a flame retention nozzle. On the bright side, lots don't need a nozzle in forges.
  4. The biggest failing of ceramic fiber blanket is de-lamination; and that is only before it "takes a set" after two or three heat cycles. If you use rigidizer and heat the treated blanket up with your forge burner, then no de-lamination after that. All you need to hold rigidized blanket in place is a few screws inserted near the bottom of the forge sides. The weight of the refractory layer can be held in place by end tabs at front and back of the forge shell.
  5. "Circumstances alters cases." Mabe he needs to shape up the performance of that heavily reducing flame before worrying overmuch about overheating the flame retention nozzle. Fortunately his problem rests at the other end of his burner, so He can always get back to the nozzle later?
  6. All naturally aspirated burners have minimum and maximum gas pressures for adeqate flame control; we call that their turn-down ranges. Huffing is a strong indication it's time to turn up the gas pressure a little. If you can't turn down the gas as much as desired, it becomes time to build a smaller burner; we all do it
  7. Putting on the breaks The fuel gas and air mixture benefits from turbulence and speed of mixture flow. Swirl provides maximum mixing with minimal breaking of the mixture flow's forward speed; this is why--so far--it is the only acceptable form of turbulence throughout most of the burner's length. The exception is in the flame retention nozzle; here, maximum breaking and zero swirl is the goal.
  8. With your burners, that is what is needed.
  9. A thing of beauty may not be a joy forever, but we must take what we can get
  10. Um, BTW...congratulations on a very nice flame in a very nice forge; we don't want to forget mentioning that in our rush to help you We didn't use to have an embarrasment of reaches, but this year so many of you are doing a grand job with your first antempt that we may start takcking you for granted
  11. I really like YouTube. After twenty years designing burners and forges, separating the wheat from flax is just reflex. Too bad about all those newbies trying to choke down a bowl of flax, but that's life...
  12. Did you run across mention of Morgan's K26 highly insulating hard bricks?
  13. What gives me a kick is the role reversal. It is he doing the teaching now, and we who are doing the learning
  14. Progress The heart of a naturally aspirated burner is its gas jet. A hot, efficient, gas flame depends on adequate gas and air mixing, but it also depends on a fast flow of the gas/air mixture down the burner’s mixing tube. Initially, the home built burner had a small hole drilled into the side of a its gas pipe, and compressed fuel gas was forced through it, creating a weak and rapidly expanding gas stream. The low pressure area caused by such a stream was barely able to induce sufficient air to create a neutral flame. Extending that hole into a tube shaped orifice produced a fast compact gas stream, and acceleration of more induced air; from this, all the rest of the burner’s performance springs. The Bernoulli Principle is a naturally aspirated burner's motor, but how you engineer the motor is important. Lengthening the gas orifice into a tubular exit with MIG contact tips, (and then by capillary tube), was followed by placing the tips in the end of the gas tube; that was followed by streamlining the joint between tip and gas tube, which also made it easy to position the tip end and mixing tube entrance for maximum air induction. Recently, Curtis (AKA Another Frankenburner) has improved air intake design as radically as the MIG tip improved gas jets; with equally startling improvements in burner performance (see the 3D Printing thread to follow his progress). Next will come homemade ceramic flame retention nozzles. There is a continuing progression in all of these improvements; each one enabling the next.
  15. I don't see h0w we could end up giving bad reports on the--by far--hottest burners around; just not in the cards
