Instructables
Picture of Natural Gas Burner V2
Ok so I’ve made a few changes, upgrades really, to the burner since my last post. I’ve pretty much revamped the whole thing hence the new instructable.

The basic concept behind this burner was to make the nozzle interchangeable so that the unit could work as both a forge burner and a foundry burner.

Essentially the unit breaks down into three parts: the fan mount (I used the one from my other burner), the mixing chamber, and the nozzle. When connecting all the peace be sure to use pipe dope or plumbers tape with the exception of the nozzle and fan attachment areas, as these will see the most ware from change out. if you choose to make the connection more permanent go ahead and use the dope or the tape.

Step 1: Parts

Similar to my other post you could find most of the parts at your local hardware store, such as HomeDepot or Lowes. The only thing you might have difficulty getting is a fan. I used the same fan from my other burner, but looking back you could probably get away with a hair dryer with the heating element removed.

Aside from a fan and a way to mount it, again see my other post. You’ll need the following

Mixing chamber
2”x10” nipple
2” coupling
½”@90 black elbow
2 - ½”x6” black nipple
½”-¼” reducer (we used brass)

Nozzle
2”-1 ½” reducer
1 ½”x18” nipple
1 ½”coupling
1 ½”x6” nipple

How about those burner tip images!!??
