Subject: Re: Lanny's Simple Camp Fire
Stove
Dear Lanny,
I have thought that this solution might be a great candidate
for a "World Stove". It is simple, inexpensive, has really good heat transfer
to the pot, and removes smoke from the kitchen. Sam Baldwin and Micuta used
the idea in Africa showing the practicality of shielding the fire and creating
a optimal gap around the pot.
What I like best about this design is that the fire directly
hits the pot helping to cool temperatures of the sheet metal stove body, which
protects the metal. It's cheap enough that a family could have one for every
pot.
I like to add some of the Rocket parts to it: a shelf so
that wood sticks are separated, a internal grate to lift sticks above the
earth, and block as much air as you can going over the sticks and have as fast
air as you can get going into the coals. As Ron says, insulating the outer
body helps a little but not very much since the combustion chamber is so
large.
This is such a elegant stove. If you weren't going to go the
insulated combustion chamber route to clean up emissions, I would recommend
this concept as efficient and well engineered. I wish folks were building
these instead of Lorena's...
Best,
Dean
