Does the smoke magically disappear once it exists your chimney? Because your neighbors might get AQI results that aren't that great — or yours might deteriorate

Does the smoke magically disappear once it exists your chimney? Because your neighbors might get AQI results that aren't that great — or yours might deteriorate, too, if everybody around you starts heating with wood.
It's just not a good idea, period.
- chongli 3y agoA modern wood stove doesn't emit much smoke at all. It recirculates smoke through the combustion chamber (and/or through a catalyst) which causes secondary combustion. This greatly increases the energy efficiency of the stove and gives you a much cleaner burn. Not only are you not polluting your house with wood smoke particles but you aren't polluting your neighbours either!
- Applejinx 3y agoThis. Mine has the recirculation thing with extra air channels and a big ol' soapstone wall interposed between the combustion chamber and the exhaust, and you can't just start it up full of wood, you have to fire it properly at which point it's hot enough to burn its own smoke, which you can see happening. And then once it's going, engage the catalyst, which also burns the smoke more, until there's basically nothing left. No more 'nice cozy smell of neighborhood wood fires', but on every other possible metric, way way better.
- gvurrdon 3y agoMay I ask what brand of stove you are using?
- nkurz 3y agoIn case he doesn't check this thread, and because my stove mostly matches his description, I'll mention that I'm happy with our Progress Hybrid by Woodstock Soapstone: https://www.woodstove.com/the-progress-hybrid-wood-stove https://www.woodstove.com/the-progress-hybrid-wood-stove
- gvurrdon 3y agoThanks. Looks like it's for a house much larger than mine, but that offers a hint of the sort of design for which to look.
- Applejinx 3y agoIt's this one: https://www.hearthstonestoves.com/product/green-mountain-40/ https://www.hearthstonestoves.com/product/green-mountain-40/ Before, I had a teeny Jotul 8. The new one is not only better at making warmth, it's also waaaaay lower emissions :)
- gvurrdon 3y agoLooks good, thanks. I'm somewhat constrained for space and room size, but might look for that or similar to replace the current one: https://www.agaliving.com/products/catalog/stoves/little-wenlock/7714 https://www.agaliving.com/products/catalog/stoves/little-wen... Stoves are useful in my area as there's a lot of wood around, often for free, though it does of course have to be dried.
- recursive 3y agoThere's nothing magic about it. Sufficiently high combustion temperature reduces particulates.
- nkurz 3y agoI was responding to the specific claim that woodstoves cause measurable problems with indoor air quality in the houses where they are used. I'm willing to believe they can, but in my direct experience, mine didn't. I live in a rural enough area (less than 1 house per sq km) that my neighbors are unlikely to be affected by my woodburning, and I am not likely to be affected by theirs. The question (and I agree it's open) is what effect dispersed burning has on the larger scale environment. My current belief is that local wood harvesting and burning in a modern efficient stove is better than the alternatives currently available to me. If you have evidence to the contrary, please provide it rather than just making blanket statements.
