GAS FORGE PLANS
| Each part of the burner is designed to be disassembled if need for replacement. However, when moving the burner it should be leak tested with soapy water before use.
The burner assembly starts with two 2" pipe nipples and one 2" elbow. The upper nipple should be black pipe, but the lower one may be galvanized for it will not recieve much heat and be somewhat air cooled. At the bottom of the lower nipple an air gate was made by hack sawing half way into it. Then a hinge welded onto the nipple with wing nut to tighten the air gate. A 1/8" pipe is welded in the center of the elbow and a brass pipe cap screwed onto the end of it, just past where the elbow threads onto the nipple. A 1/16" hole was drilled into the center of the pipe cap to make an orifice. This allows easy removal and replacement of the cap. From the 1/8" pipe, an elbow connects to a needle valve, 1/8" copper line, then brass fittings to the regulator hose. The upper nipple has a target style flame holder installed. It was made from concentric pipes smaller than the 2" nipple allowing about 1/8" space between them. 1/8" rods were used in an "X" pattern on front and back of flame holder. This assembly was held in place with various sized nails to space for welding, then nails removed. The unit was then placed into the 2" nipple, centered, and then welded to it. The burner may be cooled by the fan after turning off the gas. This lessens burnout of the flame holder. |
