A couple nails no big deal. But are the 4x4 and 4x6 pressure treated?Fellow wood burners:
Thoughts on burning dimensional lumber with 'one or two small nails' per 4x4 or 4x6 in a catalytic stove.
Considering a FB ad.
Burning in a Ashford 25.
Thanks in advance for your thoughts.
The ad states kiln dried. I asked and seller said 'not treated'. With a full firebox, tightly packed, maybe potentially as many as 10-12 nails per load, but probably less. Noting that these could be nails of any type (galvanized, copper, stainless) wondered if the high temps might burn off any coating and effect the catalyst?Fellow wood burners:

I dont know that i would risk itThe ad states kiln dried. I asked and seller said 'not treated'.

Yup. My conclusion after cogitating.I dont know that i would risk it
But nails can potentially damage the catalytic combuster in their stove. Thats the whole point. If it wasnt a cat stove I agree 100%. But it is and thst means there is concern.It presents no problem at all, I have burned much lumber and pallets in my wood stoves. Just use a magnet to grab the steel from the cold ashes later. The problem is stainless steel nails (trim nails and corrugated staples) will be a manual picking. Usually found on crates with plywood and such. Most pallets and lumber just use cheap steel nails or steel screws and go right into the stove.
If you ashes will eventually find the trash can and not your garden or back 40, then do not bother picking the steel out.
I agree. The inside of the stove is quite a bit of metal and with new stoves that metal has a certain amount of paint or some sort of anti-rust coating that usually burns off after a few fires. The manufacturer doesn't seem concerned about this. Plus, you make another good point, these stove catalytic converters are nowhere near as elaborate as automotive converters. You're nose can easily tell the difference in the smell of the exhaust from a car with a catalytic converter and one that has none. There's not hardly any difference in the smell of the smoke from a stove with the catalyst engaged or bypassed. It still smells like woodsmoke. I would venture to say the catalyst isn't all that particular about what goes through it nor is it doing as much as we would like to believe.> But nails can potentially damage the catalytic combuster in their stove.
Please explain how the THEORY on how that would work ???
Since the metal to the stove (which contains stainless) will reach the same temperature or higher then the nails, which are a minuscule part of the load and mass.
Stainless nails and staples will not even be close to melting at 1000 F degrees, so, no off gassing there. Maybe the coating on deck screws, but, from experience nothing happens to them except being embedded in charcoal instead of wood.
I was close to buying a catalyst stove last month, after researching how they work compared to the converters I am used to in vehicles. The ones in stoves are basically just a filter. Same with the fiberglass/cellulose type mat above the air tubes which is all the rage now,
The main reason I did not buy a catalyst stove is it took too long to change out if clogged. Though I might go back and see if the bolts where stainless or not ... that had to be removed for access. The prices for the converters I looked at were about $150-$170 so not unreasonable.
Its not a theory. And the problem is not from stainless nails or staples which are rare. Its from galvanized ones which are the most common. And the zinc can absolutely coat the cat making it far less effective. Im sorry but no a cat is not just a filter it actually burns the combustible materials out of the smoke. And the blanket is not a filter either it is just insulation to keep the firebox temps up to achieve secondary combustion. It also is not fiberglass or cellulose. One would melt the other would burn. It is ceramic wool. You do not replace a cat if its clogged you simply clean it. You replace it when its coated or depleted making it nolonger become active. I think you need to do allot more research on how modern stoves work if your going to be giving people advice.> But nails can potentially damage the catalytic combuster in their stove.

What exactly are you basing these opinions on?I agree. The inside of the stove is quite a bit of metal and with new stoves that metal has a certain amount of paint or some sort of anti-rust coating that usually burns off after a few fires. The manufacturer doesn't seem concerned about this. Plus, you make another good point, these stove catalytic converters are nowhere near as elaborate as automotive converters.

What about "pure catalyst" stoves that don't have any secondary combustion?My opinion, and it is only an opinion based on personal observations, is that most of a modern woodstove's efficiency and clean burning characteristics are from good design, especially secondary combustion implementation. Adding a catalyst helps somewhat, but good stove design is doing most of the work.
I haven't used or been with someone who has a "pure catalyst" stove so I can't really comment on how they work. I'm guessing since they meet EPA specs, the catalyst must be doing something.
No opinions are always welcomed. But when an opinion contradicts clearly established facts expect to be called out on thatAs I stated, my opinion is based on my personal observations of my stoves. I am not making claims or asserting facts. Since I don't have experience with as wide a range of stoves as others on this forum I guess that would make me at least partially ignorant.

I guess that's the point I'm trying to make. A catalyst should be making an observable difference - less smoke, a different odor, or something else that tells you it's working, and a way to tell when it's not working and needs replacing. I haven't observed any difference in odor with my Progress Hybrid. Maybe I need a new cat - after 1 year ?I can smell a difference with my BK when the bypass door is opened vs closed. With the bypass door open it smells like campfire, with it closed it doesn’t smell like campfire, I can’t describe what it smells like, something I’ve never smelt before but definitely a different odour.
Different companies, different engineering? I would assume there is a test procedure in your owners manual?I guess that's the point I'm trying to make. A catalyst should be making an observable difference - less smoke, a different odor, or something else that tells you it's working, and a way to tell when it's not working and needs replacing.

No you have a hybrid so unless you are running it low enough that your firebox is below the temps needed for secondary combustion to occur where the cat really shines you wont see a massive differenceI guess that's the point I'm trying to make.
