I’ve seen YouTube videos of small iron/steel rocket stoves, and some in-home Rocket stoves that have huge furniture-shaped cement like heat accumulators.
I want the best of both, and am looking for advice.
My basic design is like the simple outdoor/camping RS’s you see on videos on YT, but larger. I want to use a 5”X5” steel pipe, 5.5 feet to 6 feet in height, with the fuel loading/air induction pipe at a 45 degree angle, as are the simple outdoor RS’s on You Tube. But I don’t want to build a cement-like structure lateral to the stove’s location, using 10/15 feet of floor space, and hundreds/thousands of pounds of sand, cement, etc.
My idea is to use the vertical pipe with metallic “bucket” or “flower pot” structures (maybe two, or three) up the primary pipe from the fire as heat accumulators.
So, about 18 inches above the area of fuel induction, I hope to drill approx. one inch holes through the primary 5 inch stove pipe to allow small one inch metal tubes to cross through the bigger stove pipe, and be welded to the stove pipe, so as to be water proof. Then build a bucket/flower pot shaped steel holding pot structure, maybe 15/20 inches in diameter, welded to the stove pipe at the bottom of the holding pot, and open at the top, surrounding the primary stove pipe. This way I can pour a dense sand in the holding pot, and maybe some water, to allow heat from the tubes that cross through the stove pipe to accumulate in the sand in the holding pot(s). I don’t want to pour permanent cement into the holding pots (I know that would be a denser heat accumulator than sand with water) as I want to be able to disassemble the stove for cleaning and storage in warm weather months. I can dip/spade the sand out of the holding pots from the top when I want to disassemble. I want a total weight of maybe 250-300 pounds, when the holding pots are full of sand/water.
My question: where can I buy the densest sand available? Apparently Hematite sand is one of the denser ones sold. Does anyone know if it is sold at Lowe’s/Home Depot like stores?
Any advice? I’m going to get a local welder who is also a stove builder to do the work, and will use well-insulated materials for piping the smoke out, but hopefully can retain a larger amount of heat from escaping through the “chimney,” than traditional stoves and fire places.
