This burner does not need an expensive blower. And here's the ugly casting after opening the mold. Have you been deceived? Mankel Forge was started in the late 1960's by a Michigan Farrier, Ken Mankel. ODC (orifice discharge coefficient) : gas jet will flow 68% of the gas that a perfect orifice would flow. For safety the propane tank should be further from the flame, but in this case I wanted it to be obvious that the propane tank with low pressure barbecue regulator was powering the burner. 96. So much that moisture in the surrounding air freezes on it's surface creating the "frost" layer. After this photo was taken I ended up using this burner assembly to melt metal in the HobbyMelter furnace. The forge itself can be made in any configuration…pipe, tube, fire brick or just about anything one wants to heat steel ... holes in the baffle to allow some air to pass thru. But they are also wasteful compared to blown air burners. Gas flows from a gas tank to the forge chamber through the burner. Burner Nozzle is a stepped nozzle made of 304 stainless steel for higher efficiency and longer life (Burner Nozzle’s diameter is 38.2 mm). The only change is that I removed the original propane hose (it was only about 2 feet long) and replaced it with this clear vinyl tubing (an actual 10' long propane hose would be better). Available in two sizes, 1" and 1/2".

ATM: Gas pressure from gas pressure regulator (in Atmospheres). Use at least 2" of insulation around the chamber: The first inch or two should be Kaowool - the … A blown air burner is different. A gas forge burner provides heat into the forge. This design utilizes a MIG welding tip to accelerate the pressurized propane to high velocities down the burner … The forced air burner runs much hotter, heats faster, and allows you to adjust air to gas ratio for optimal heat and gas usage. This design requirement also makes burning natural gas in an atmospheric burner pretty much impossible.

Using an air blower on a gas burner. hot spots as in a venturi burner forge and combustion is complete at the burner and not dependent on the swirling motion of a blown pipe forge. Likewise, counter-clockwise rotation will provide minimal air, and therefore a lower flame size. The typical homemade atmospheric burner requires a high pressure regulator to blast propane through it at over 10 PSI, creating a low pressure zone or "vacuum" in the burner tube to suck in oxygen for combustion. Propane is stored in the tank as a liquid. This is necessary to prevent excessive oxidation and scaling of the metal. Using an air blower on a gas burner. 139,565.
