Seems to work well- I make mine from empty disposable gas cylinders, when I can get hold of them. Here in the UK, the disposable MIG gas cylinders nest into the Rothenberger/Go System propane and MAPP gas cylinders with just the right clearance, and I make a twist lock mechanism to keep them together, and a loop to hook them out- they can then drop into any old bonfire, but I normally hang them vertically so that the tar gases feed back into the fire. One thing I need to get past in selling the idea to others with wood stoves is that once fully charred, they either have to be hooked out hot, or left taking up space in the stove until it’s cold. One thing to beware of is the avalanche effect- more heat=more gas=more heat, so scale up carefully.
One other thing- and I’m 99.9% sure that I’m insulting your intelligence- make double damn sure that gas vessels are empty before cutting them, and drill the propane cylinders and fill them with water.
