Sustainable Berea wanted me to build them a couple of rocket stoves to be used with woks for stir frying lunch during their local Solar Tour.
I bought a couple of 14” steel woks for cooking and a 14” stainless steel wok and a 13 quart stainless steel bowl for skirts.
I used the stainless bowl with 4“ galvanized steel stovepipe and the stainless wok with 4” stainless steel stovepipe.
I used 4” Tees for combustion chambers, 2x4 metal stud piece for feed chamber and expanded metal for grate and back wall of combustion chamber.
I used 6 gallon metal buckets for the shells.
I put a 1” thick piece of ceramic fiber board under the bottom of each Tee.
I put an 8” stovepipe outside of the galvanized steel riser to reduce overheating and insulated between it and the bucket with fiberglass insulation.
I insulated around the stainless stovepipe with two 1” pieces of ceramic fiber blanket and between the ceramic fiber and the bucket with fiberglass.
