FINALLY a new wood stove design experiment idea! Ceramic fiber board lining with heat exchanger.

 OK I ordered the ceramic fiber board. The stove is 18 inches long and 11 inches wide and high. So the fiber board is $120. So I figured I can maybe put fiberboard on the front door if I need to keep the steel from overheating. haha. Also I'll get 8 inch stove pipe AROUND the 6 inch stove pipe. So I'll get bolts to hold the 8 inch centered around the 6 inch - unless you have a better idea. Do you think that heater exchanger will work instead of having the cold air inside the hot air? Cuz hot air expands - seems like it should work. I'll then see if the water in the big pot stops overboiling and evaporating since water has twice the heat capacity of paraffin wax. thanks again

 

This playlist by a Minnesotan - includes three videos on his stove design 

So I'm not planning on the SAME precise thing - as per above - I plan on doing a different design slightly.

But the goal here is a CLEAN burn that will stop any creosote from forming - and should prevent me from needing to totally dismantle my chimney.

  With repeated heating and high moisture content, the ignition temperature of creosote is generally considered to be 451 degrees

With this design I should be able to have a fairly maintenance free duct pipe system without creosote build up. 

I might have to replace my previous duct pipe if it has too much creosote and so is a fire hazard. 

I will bring up the flexible camera I got to check out the duct pipe for creosote. 

But there shouldn't be that much built up where it is a real hazard - if it catches on fire and ignites then the burn temperature can explode the steel duct pipe. 

165 F. is the ignition temperature of creosote. Don from Fourdog says he burns off the creosote each time by opening up the stove to full power - this is what I always try to do - so that if the creosote is at a small enough amount - then it's not a hazard if it burns off.

So if I get this set up then I will DEFINITELY burn off any internal creosote - the only question is how much do I have built up that has not burned off yet? I insulated the outside chimney - so ...

 He actually has TWO inches of ceramic board on top....

I should have enough left over to manage something similar.
