Since this discussion included some of the stoves that first developed secondary burners I would like to share what I found this morning when looking at a used Osburn stove online. I try to do as much research as possible before I purchase a stove. I found the Osburn site http://www.osburn-australia.com/en/about/history Here is part of their history.

"Mr. Mills became sole owner of the company in 1985. In its early days, the company produced only wood stoves, and in 1980 it became the first-ever North American manufacturer to make a wood stove in compliance with Oregon State's strict air emission standards."

They must have had some type of secondary burn system but 1980 There stoves today are on the pricy side but they look well built.

Not sure. I think Craig posted many years ago that the Avalon was the first stove that was a secondary tube burner, but there were other clean(er) burners in the early '80s.

It seems you mentioned this before It may very well be that Craig is correct but though we could toss this history into the mix. Now I am somewhat interested in how the older Avalon's and Osburn stoves were made.

Regarding secondary burners, I have seen in my DutchWest FA264CCL, which had controlled secondary air on the top left side feeding tubes ending (and thus providing pre-heated air) under the cylindrical combustor in the top middle of the stove, that if one plays well with the primary air (in the door on the left, over fire) (and of course keep the air in the ash door closed as it's for coal burning), that one can have secondary flames coming out of these tube as well. Get it hot, decrease primary air, and do not increase secondary too much, and it works.

And my stove was "tested" according to the label in '83.

While the air may have been meant to supply oxygen to the combustor (a thing I believe most stoves now don't do anymore b/c primary burning leaves sufficient O2 for the combustor), in the right mode one could get secondaries there.

I played with it, but refrained from running that way for long as I was afraid that the (ceramic) combustor would be damaged from having flames too close or touching it. I always thought I could use this as a relatively clean back-up mode if my combustor failed before I had another one...

I think the first Avalon had a single secondary tube, but don't hold me to it.

stoveliker, I was not familiar with the DutchWest FA264CCL so just watched a couple of videos on it. The one shown in the video was a 1985 model. Very nice looking stove and I like the idea of feeding the wood from the side. I am sure they have improved them since the 1980's. The one Blaze King I rebuilt some time back has secondary air under the combuster. It sounds like your are still using the DutchWest or have you upgraded?

begreen, Very hard to find a history on the Avalon stoves could not even find an older manual as they sometimes have a diagram of how the stove works. I guess we might not ever no how some of these older stoves were made.

I upgraded to a (modern) Blaze King Chinook 30.2. A very nice experience in burn time (on my first try of a long burn, I got 24-is hours. Of course it was between 30-35 outside, but even in dead winter (but on Long Island, not Idaho...), I still get 12 hr burns easily. In fact, 14 hr was more common, which was a nuisance because one has to push it keep a decent refill schedule.

Chimney was utterly clean (non-insulated, double wall in masonry outside), only some dry crud at the bottom elbow - which was singe wall).

Thanks for you reply and info on your new Blaze King Chinook that is a very nice looking stove. With a 12 to 14 hour burn time you will sleep well at night. Having a clean chimney is always nice. Those days of getting up a couple of times to stoke the fire are long gone for most. I just got a very nice used Country Striker for my shop and fixed it up and am getting excited about putting a fire in it this fall.

I guess other than the Avalon/Lopi we are still searching for which stove company/model had the first tubes in it. Good thread!

Let’s not forget about the wood stoves that had secondary air without tubes. We know Avalon/Lopi had this feature and likely others did as well. None come to mind at the moment because I wasn’t really dwelling on the subject when I got an alert on this thread.

For the sake of other newbies reading this thread into the future who may be interested in the history of stove design, especially as it pertains to secondary air function and where it came from.

Stove designers were well aware of secondary air function 100 years plus prior to modern wood box stoves and incorporated it into many of the much older stove designs of the 1800’s to early 1900’s. More research in this can yield some interesting reading. Those guys were smart designers. It is highly likely more modern stove designers built upon this prior knowledge.

For the sake of this discussion though, I believe it was me who asked earlier in the thread (now some time ago) which stove company had the first secondary air “tube(s)”.

So far, we’ve come up with Avalon as maybe the first with a single secondary air tube. Lopi is real close in there as well...and as Begreen has mentioned likely came from Lopi acquiring Avalon. Perhaps there are/were others. I’ll have to look into the Dutchwest. I’m not familiar with that one.

The early Federal and Kent stoves had secondary combustion systems. Worth looking at their histories.

To be clear, the "federal" and the "Dutchwest" are (at least for the iteration I had) the same : it was the DutchWest Federal Airtight (FA) [264ccl].

How mainstream were these in the U.S.? Anyone have any idea. I’ve never heard of them. During that time frame in my local, Buck was the hands down most popular stove.

We still see a fair number of Kent's. I would say Alaska's and fishers were probably the most popular here. Some bucks but not nearly as common as many others.

Our 1001 had 4 secondary air tubes (mentioned earlier) and a combustor. (First hybrid) The design drew air from the room and placed it below the combustor, contributing to thermal shock. 70 degree room air was not a great design. Air needs to be heated prior to introducing it to the fire when a combustor is also used. That was 1983.
