Homemade secondary combustion in old woodstove
HTML-код
- Опубликовано: 13 сен 2024
- I bought this stove for $125 and restored it for my workshop. I got a lot of good ideas from looking on youtube at homemade secondary combustion and also from stove companies. Also i got good ideas for primary airwash systems, baffles, and bypass dampers. I came up with my own designs and since I have experience in fabrication and welding, I knew that i could build them. I also had a local fabrication shop that bent the steel for me and that i bought the supplies from. Everything worked very good and in the future I will be adding more secondary air manifolds to the sides between the top and bottom fire bricks and also i will be bring more super heated primary air in for sustained secondary burn. Thank you for taking the time to watch this video... and sorry for the shakey camera.

Nice job Denny. You ended up with the performance of a $3500.00 stove, for $700.00 ! Plus the satisfaction of restoring and hot-rodding it with your own hands. What's not to love about that... Kudos dude.
Absolutely beautiful. Spectacular job. The finest stove project result I've seen in 11 years on YT. Kudos. Congratulations.
Great to see the secondary air being drawn in when the primary air to the grate is reduced. Nice job.
Impressive rebuild. Agree with guy below, lots of fabrication skills, shop tools, time and money. A joy to behold.
A little late but I just stumbled onto your channel but never to late to compliment someone on a wonderful job. I mean it's an heirloom and then some. Glad I watched and glad,thankful and delighted you took your time to share. Thank You Denny !
Figured out the air wash/primary air set up. it took me a bit to figure it out but it's an ingenious design.
I couldn't see how that air wash frame connected to the 2x primary air intakes. I'm assuming that frame sat just inside the doors... Are those slots facing toward the fire or toward the glass? I'd love to see a side view sketch or something. Cool project.
Come funziona l aria primaria e airwash ?
You've got some serious skills Denny. The stove is beautiful, and you saved it from ending up in a landfill. Well done! We just bought a secondary air stove. It amazes me when there is no smoke coming out of the chimney. It's so cool
Kudos - after getting the basics of wood stove engineering this has helped tremendously with understanding the intricacies of efficiency etc.
Love that long slow secondary flame, a beautiful thing, not an easy thing to achieve. Nice work.
Thanks for sharing - I like your design of the air intake for the secondary combustion - impressive to see the almost magic dance of the flames - and I fell this is even more interesting to look at than the more traditional look into the burning logs.
Hypnotic! It fascinates me to see how the secondary burner works and how hell resumes at the top. It's just great.👍👍👍
I could sit and watch this all night good job
Very impressive work, and from the look of the flames, very efficient too. Nice job!
I spend ages just watching it burn like those fireplace videos.
Stove manufacturers could learn a lot from you. Great job.
Impressive Build - well thought-out, and I could watch those flames for hours. Nicely Done, thanks for sharing!
Excellent song choice! "Burning down the house"
You my friend, have some very nice tools. Beautiful work, the stove looks sharp. I admire a can do attitude. Everyone is quick to go buy, but I'd rather build!
i guess I am quite randomly asking but does anybody know of a good site to watch new movies online?
The trick to making clay work as a refractory material that doesn't crack readily or crumble is to mix one part of good high firing clay to two parts sand. Perlite or vermiculite will also work well with better insulating properties and lower weight. I recently added a good shape to the inside of my stove that funnels air into a narrow burn chamber, and greatly improved the efficiency and ease of use. You can just throw the wood in at random once it heats up and it will burn cleanly and completely. You can even burn damp sawdust.
Can you upload a video of your wood stove modification? thanks
Yup one of the better distributions I've seen great secondary
Very nice, boy the glass doors made all the difference! And adding the secondary burn tubes made it more efficient. I like it!
Wow. Very nice.
you're a rare breed. Really amazing work on this. Not that I have the capability to do something like this, but if I did, I would have put the secondary air collecting tubes inside the stove itself and also constructed the baffle in such a way that it could be insulated with kaol wool. Between those two adjustments, you'd be able to keep the secondary air extremely hot. It looks like you have to give the stove quite a bit of primary air to keep it going, although toward the end of the video it does look like you're getting a true secondaries-only burn. If that's what most of your burn looks like, then awesome. Doesn't get much better.
Great job, Denny. Looks like it works extremely well.
The design seems to work very well, the flames burning from the secondary air holes tell it all.
As mentioned by others, you could provide an outside air source.
That would be a very easy alteration for the secondary air, remove the pipes which run under the stove and make an air box from large box section at the rear bottom end of the tubes.
Feed in air from outside via a 80mm spiral duct straight trough the wall, provide a bit of downslope to the outside to keep rain and condensation out, a vent cover with mesh needs to be provided to keep rodents out.
For the primary air it's a bit more involving on this stove as you don't want unsightly air ducts to the regulators on the side, maybe close these off and make a steel duct on the inside of the stove to your primary air ring, and the regulator on the back.
Sometimes I’m just mesmerized by the dancing flames of our secondary burn insert which is raised off the floor like yours. Just upgraded the stove this year at cabin.
Wow! That is excellent! I realize this is an old video but has to be said, again. Great work here!
Great Job! Well done.
Awesome job mate, what a ripper setup and awesome skills you have!
it almost looks like a propane burner. all that extra heat being made just from the super heated air. thats awesome.
That is some very impressive work there. Im inspired to do it for myself now and save some money on a new stove.
Good job! Im impressed with the secondary inlet burn bit, and all of it really, very tidy! Well done you!
Nice build, thank's for your time and for sharing.
Pro Level Bro! Good Job.
this thing is really working 1st class.....great project!!!
Most of this video reminds me of the BURNING LOG channel at christmas time.
I am supprised you did not start from scratch. It's a very good job. I have made my own stove as well. It looks like a lot of work but worth it.
Looks like a Balrog when it's burning. Thats amazing secondary burn.
Thank God for people like you in the world lol, cause if not I would just be cold and smokey lol. Janice
Seeing the second burn is quite satisfying. Nice job.
Too bad Fisher stoves and other tank like American made stoves from the 80's didn't get retrofitted like this. Very well done.
Well I ended up here b/c I was thinking of tackling building a wood stove.
I have one right now, but it's old & inefficient.
I wish I'd just thought to read the description before watching the vid, b/c I was waiting for you to talk
and EXPLAIN what was going on, lol..
Excellent stuff bro
This is a very well thought out gasification stove.
Kick ass retrofit, a lot hard work and planing, nice job Denny!
Great video, good work. All the basics of a good modern clean burning woodstove seem to be here
dude thanks for that post....its very good ... love the tunes... the secondary works really well ...
You put a lot of time and effort into making this your baby, it's Beautiful!
Thank you. I get about 15 hours of good burn time and about 22 hours were I can still start a fire off of the coals.
Puoi spiegare meglio, l aria primaria e air Wash ? Grazie
That is a bad ass design you came up with!
Nice setup with 1 nit...
The welds
My cheap ass does CO2 shielded MIG on thin household Chinese steel salvage,
I recommend it for practice as the stuff has horrible paint that will test your skills.
I have 1 arm ....
General rule of thumb, each leg(not the face of fillet)1.5 x thickness of thinnest material MAX
In this case 1/2 of weld material volume would suit as stress is minimal
With practice you will find directing flow to thicker piece and washing onto thinner helps control heat.
Cheers👍
Very Nice 👍
Looks a good well done you've had time to think and play about
It’s just like a Lopi now. Nice job
I decided to dampen mine down bit, so instead of running 700-800 degress (too hot for my house) I run mine around 500 and the stack temp is down to 200 or so. A full load used to be gone in about 4 hours, no I get 7-9 hours out of a load, and it way more efficient. The secondary tubes make a world of difference and no smoke now.
Can you provide a picture and/or video of your stove? When you dampen it down, does it smoke a lot?
Nice to see working so well
I like to sit there in front of that stove.....absoluut clean burning and what a nice flames . Toppy... and good hand worck too.
Iv never seen one work so well. That's so impressive, it looks like gas coming out of the air holes it's working that well.... hmm to convert or not.....
One way you could improve this design would be to draw combustion air from the outside rather than from the room being heated. This in effect creates a heat cushion of positive pressure rather than creating a vacuum in the room that draws in cold outside air.
nice job. will study your work to see if i can benefit. thanks.
very nice engineering work
also music was good
awwesome build. love the look of the burning . i'm jealous.
Very impressive, nice work.
that's is a beautiful stove. guud job dude. look very professional
That is one non smoking hot looking redone wood burner ! Looks like that took a lot of work but looks well worth it.
Cool project - If I had all the equipment & know how, I'd do the same stuff with my old stove instead of dropping $2-3K on a new one that does (essentially) the same thing. Great soundtrack (f*** the haters - Talking Heads rule!) ... superb paintwork.
Nice work-good secondary burn.
Best video of this type, thanks for sharing
Great design and build!
Nice stove, hypnotizing..
Excellent work. I wish my welds were as good.
Wow, that works great! Good job
Nice clean looking build 👍
looks good
very nice job preheating the 0xy
Astounding - thanks for posting.
Burning wood gas. Very nice
Thank you sir for your reply.Once again great job.
Lots of secondary combustion and a nice fabrication job, good work. I'd be interested to see how the burn looks if you turn down the primary air a bit to get a nice, slow, lazy burn. Then, I find anyway, loads of heat, a clean burn and very good fuel economy
Nice job, looks like it works well.
now that's sweet!
Do ya think your baffle plate is heavy enough ? Wow you did an absolutely amazing job on this old stove !!! I sold stoves for years and I have to tell you what you have done to this old stove is out of this world !!!! Thank you for the wonderful video ! Your neoceram front stays cleaner than my old Avalon 1190 that has the new technology ! You my friend are a mechanical genius !
if he used ceramic insulation it's good for over 2000 F.
@@voidisyinyangvoidisyinyang885 Yeah we used a boat load of the Kao Wool over the years. It is amazing stuff!! I had an old Lopi in the basement years ago that just had a straight through with out much of a baffle . I placed a sheet of steel and some kao Wool on top of it and it made an amazing difference. You are 100% correct it is a great insulator.
@@752brickie This vid just inspired me to order 1/2 inch stainless steel tube. I found a coupler on one site and 24 inch of tube on another site and a 90 degree elbow on a third site - all in stock. So I will feed it through the primary bottom air hole in my wood stove. I will add the ceramic insulate baffle all the way to the back and make a small opening to have this elbow go up above the baffle in the back. That will ensure more oxygen to burn off the gases. This will decrease the front oxygen level but should be ok - as it will be a slower hotter burn as a secondary burn once I get it up to temp.
Great build .
Excellent job.
nice project. for the majority of us mere mortals, this would be outta reach, though. i'm off to the hearth store^^
My favorite part starts at 26:35
Thank you 😊
Man that looks like it works AWESOME... I have a 1908 glen wood wood palor wood stove. I want to do something similar to that.. nice video thanks...
thumbs up..
at 26:35 that is all wood gasification. for them who don't know,, it is the flammable gasses coming off the burn = smoke you see out your chimney. nice view of the after burner....
NICE VIEW AND GREAT SHOW OF THE SECONDARY BURN = AFTER BURNER....
it still amazes me how that works.. I love it.. thanks
THANKSGIVING
That is by far the best second burn design I have seen in action. ?how has it functioned over time ?same efficiency. ?do you still have creosote in the exaust raiser, I'll bet not nearly as much. Good job young man.
Awesome!
Outstanding job. Mount the camera on a tripod, from low angle toward fingers of secondary flame and play some Christmas music. Very, very impressed with your work.
What good are the videos with out any explanations?
Very cool! Nice job!
I just subscribed to you for the 3rd time and I have never un subbed. Please thank RUclips for cheating you. Jim
Ill loock in to it more im puthing your vid in my favorite
Nice secondary burn!
I thought the music was hilarious... I mean what could be funnier than a song called burning down the house??? well played sir
i suppose its better than billy joel or prodigy fire songs
Nicely done
Could you provide me with a list of resources you reviewed in order to understand the principles and design of secondary combustion wood stoves that allowed you to construct this. I want to wrap my head around how secondary combustion actually works. Any books, videos or other resources you used would be greatly appreciated as I am having a hard time finding good info on the subject matter for some reason. Ive contemplated reverse engineering a Kimberly stove.

you are very skilled at fabrication. excellent high quality work. the secondary burn is working. but I question if it really adds much btu's or burn time to heating with this particular stove ? i.e. if you are burning it at 800 F stove, and the pipe is 400 F, it's still only 50% eff. just smoking less. is it getting longer burn times at maximum or sufficient heating temp ? not smoldering a long time and creosote-ing up the chimney. I'm highly skeptical of these improved woodburners because I've read and seen so many that didn't perform as advertised. it would have to seriously add to the burn time and use a LOT less wood to make it worthwhile. the best heating stove I ever saw in my life was an old Franklin from the 70's. close the damper with a full load with draft closed, and it would heat 3 floors and you had to leave the basement. that's how hot it was. it used 6 cords of wood/year but was heating a pretty big house
