Forge Burner

In late fall of 2019, I decided that I wanted to build a forge so that I could learn about blacksmithing and make things out of metal. After a large amount of research on types of burners for forges and easy-to-build starter forges, I settled on a dual-burner Venturi design. This design utilizes a MIG welding tip to accelerate the pressurized propane to high velocities down the burner tube. This also pulls air down the intake valve, mixing the air and propane as it travels down the burner. As the burner opens up, the propane ignites.

This design utilizes an air intake valve and a pressure regulator, allowing for easy control and adjustment of the flame. Propane travels from the tank into the pressure regulator and through a tube to a ball valve. This ball valve can easily shut off the flow of gas to the burner without effecting the air intake or pressure regulator. Then the gas travels to a 1/4’’ pipe and splits into a T. Here the T enters the main burner pipes and a MIG welding tip directs the propane down the burner, pulling air with it. As the propane leaves the burner it ignites.
