Building the GEK Gasifier in seven parts

Step 30 Packed bed filter - 3

Assemble filter inside

• Weld four of the 5/16" bolts on the bottom of a circle screen so as to hold it off the bottom of the filter. Position bolts about halfway from the center hole to the wall.
• Weld one 5/16" bolt in the center of the second screen circle for the top of the filter. The bolt gives a grab point to remove it from the vessel
• Pull apart 4 rolls of steel wool into flat strips in preparation for packing the filter
• Pack the filter. Put the screen with four stand off bolts into the bottom. Pack the steel wool in folded layers. Make sure to prevent channels along the sides. The goal is a consistent and complete distribution of steel wool fully filling the vessel. Pack up to about 1" from the top, then put second screen on top to hold it in.
