Rocket Stove Heater

[manicman]

Hi all,
I've found a few threads on rocket stove heaters and done plenty of youtub'ing.... But has anyone done one with a 47Kg propane bottle they would share some sizes for burner tubes/exhaust diameter etc??

Any help would be great as I seem to hit a brick wall and don't want to make a mistake with the only bottle I've got.

Cheers
Ian

I did one with a 14kg bottle,tube size(well it was box) 80mm square,to small i thought for your bigger bottle i'd go 100mm no less,the 2 main points are insulate the all tube well,the distance from the upper tube to the top plate you dont want to far or to near,say around 30-40mm as this can affect the final burn.
