Clean Burn ceramic fiber board wood stove mod, part 2

 

 This is the stove that the farmer is using.

So I got ghosted by a Minnesota farmer - he stopped replying to my youtube comments. haha. He designed this cool 1100 F. ceramic fiber firebox in a "cheap" stove he got at Menards. I had to track down the specific stove - it's a Century design - so the baffle does not have any back opening to the stove collar exit. So it forces all the smoke up the front and his infrared detector actually got busted getting a reading!! The stove has ceramic glass rated to 1400 F. on the front door. Then he built a heat exchanger using two different size duct pipes and for his mass heater he uses a big pot of paraffin wax.

I pointed out to him that water still has twice the heat storing rating as paraffin wax. So I'll stick with water. My water was boiling off and so this will ironically cool down the top of the wood stove. For my heat exchanger:
The outer pipe also helps insulate any surrounding combustible components from heat traveling through the system.
I haven't cleaned my duct pipe out yet - so this new firebox will ignite any creosote - at 450 F. - so if I first surround my 30 degree pipe - at 4 feet - with an 8 inch pipe that I can drill in bolts to center it around the 6 inch - and so if I get a creosote explosion from the heat gas burning - the 8 inch should help lessen the impact. haha.
Otherwise the creosote should burn off from the heat - to clean out the duct pipes naturally so I don't have to dismantle my whole chimney system.
The outside chimney has rock wool insulation - so it should be pretty well protected.

 Here's his vid again.

 

 Yeah I get that reddish glow already if I burn my stove fully open and hot....but that's only from too much air - when I have it fully open. So if I keep if fully insulated - then the back should get less hot since there will be less air? hmm.

He has the back of his stove insulated from the fire brick - he doesn't mention that in the video. That's why I had to figure out what stove he was using in the first place!!

So this is risky to be sure.

Well I'll know if anything starts glowing reddish that I've got trouble - and just adjust the air intake.

 

so clearly the wood stove still had ceramic brick in the back - the issue now is just the top of the stove.

I guess the reburn cooled it down enough? The air intake in the front - and then reburn over the baffle...

has to cool it down back to 600.

Simple heat convection! Cool. Us hillbillies used to put a section of 12 inch stack, around an 8 inch chimney, and used a fan to circulate the air. Your's is way better.

Thanks for your comments and ideas!

That's what I plan to do - put an 8 inch around 6 inch - but maybe I should look for 12 inch - thanks
