I built a 3"x 9" ribbon burner forge a couple years ago. I built it a little too big I think and although I can get to above 2100 degrees F. I use more gas than I need to so a rebuild is in the works. What is the optimum height of the ribbon burner above the forge floor? Any opinions? Thanks.
 
Joe, I don't have a clue to the answer to your question, but since you've had no responses yet I decided to make a couple of comments. First, Welcome to the group. There are a LOT of very knowledgeable folks here. Next, your question isn't very clear - how high from forge floor for the burner? While a ribbon burner isn't as commonly used as a venturi or forced air burner I'm sure there are a few folks using them.

Perhaps a photo of your current setup, and a drawing showing what you propose could help a lot with understanding your question. Many times I find myself looking for an answer, and the drawing process helps me understand better.

Good luck. Oh, and congrats on having your profile filled out. That really helps when folks wish to help.
 
Most ribbon burners are either roughly flush with the floor, or at the top of the chamber. Size can range from 2X3" to 12X2". Orifice size ( holes in burner can range from .125" to .25". A sufficient size mixing manifold is needed under the burner to assure the gas mix at the burner is complete.

In my opinion, a ribbon burner is more useful on a larger forge than a smaller one.

Thanks for the replies. I was just curious if there was a sweet spot when it comes to the distance from the face of the burner to the floor of the forge. Should the flame be a certain distance from the work or can the work be right in or very close to the direct wash of the flame. Would direct contact with the flame cause ill affects to the steel you're working on?
 
You really don't want direct flame contact... There are some situations where you might want that, ie doing a scarf weld, but as a general rule you want even heating.
