Natural gas ribbon burner
I built a natural gas ribbon burner and forge last year and since it’s been almost a year and I’ve worked most the kinks out of it I thought I would share my experiences here. I first had to do a bunch of research online. I didn’t find any single source of information that had all the answers so I had to piece my information together from several different sources. Most people making ribbon burners were using propane but I really like the idea of using the natural gas that is already plumbed into my shop. An additional bonus is NG never runs out or requires a trip to the propane dealer for a refill + natural gas is much cheaper than propane. The problem with natural gas is the low pressure in most home lines. I wasn’t sure it was going to work but I thought it was worth giving the natural gas a try. If I didn’t have enough pressure from my home line I could always convert over to propane. Luckily for me it worked out, the pressure is enough to get the ribbon burner firing better than I imagined. I wanted this forge to have a larger chamber than my other propane forge that had a maximum size height of 2.5 inchs. The new ribbon burner chamber is 6" high 10.5" wide at the opening and 14.5" deep so my ability to heat bigger and odd shaped pieces improved dramatically.
Hopefully others can benefit from my fumbling through attempting to understand ribbon burners running on natural gas.
