The claim to be able to burn
wet bio material is especially important given he is condensing the latent
heat of combustion, therefore garnering the lion share of heat in the
material, especially wet material. Most burners - even the rocket design
looses the latent heat of combustion in order to obtain the stack effect for
draft, providing combustion air without a fan driven by electricity. I have
wondered if a condensing gas furnace heat exchanger could be coupled with a
wood stove with similar effect.
The bio char movement's thinking is to simply make the char without using
the resulting BTUs produced which I think is a terrible waste of good wood
when most of the world relies on wood for cooking. Given that 75% if the
heat in wood is released during the gasification phase there is a desire to
make the char while cooking or heating water with the resulting char sold to
buy food in the third world.
When I have a working prototype I will share it with you. I build with
recycled from the bone yard when ever possible but am conflicted regarding
the big industrial thing although I have certainly been a student of its
tenets.
Concrete is conductive and not site specific requiring a lot of energy and
high technology tooling to get at it so I am conflicted regarding its use
though I must say I have built oodles of structures with steel reinforced
concrete and also block. The foamed stuff definitely is an improvement over
solid for conductivity but I does it reflect radiant effectively? Concrete
is used as a thermal transmission mass in radiant floors as I have in my
shop - very warm and conductive.
Glad to hear someone out there talking back!
