The forced air burner runs much hotter, heats faster, and allows you to adjust air to gas ratio for optimal heat and gas usage. Natural gas such as that supplied to a residence flows at very low pressures, so the forceful jet of gas would not exist and therefore the vacuum effect would not be created and proper functioning would not occur. 3) Does the ability of a burner to hold a neat flame at its end become less important when the forge it's in heat up to the burn temp. Q. With insulation in place, the forge chamber has a dimension of 6" diameter by 11" long. While this thing looks completely overbuilt, it's just to allow enough airflow through to use very little gas.
