I don't see how it could happen, max barrel temps are in the 600F° 315C° range. It self ignites at 335C° 635F° . And theses rockets, if well made, produce an extremely low level of creosote. In mine, after a whole winter of burning, i had less than 1/32th of deposit, less than .5mm.
I'm new to the forum and fascinated by rocket mass heaters lately.
I'd been looking into masonry heaters. Soooo expensive! I'm sure the mason's are worth what they charge, but I just don't think I will be able to manage 20 to 30k for a heating system. So the rocket mass heater.
I'm wondering if anyone has any experience with creating an upright version. I'm imagining the heater core next to a ceiling height mass of cob with a zig zag arrangement of flue pipe embedded within.
If feasable, this would allow me to centrally locate the heater in the living space.
What you're looking for is perhaps something like the one shown at this webpage. No flue pipes inside, the heat distribution is based on gravity. Of course not as high and narrow as this one, and using thicker walls. But it's dead simple with a small footprint.
Thanks Peter. That is a lot to wade through, but really interesting!
I've gotten through most of the exchanges related to your experiments with those amazing incremental improvements. It strikes me that you are seeking the ultimate burn, but that may not necessarily make for the ultimate house heater. I definitely love the way it stacks up because I have already designed the house I am building with the assumption that we would locate the heater in the center of each floor to take full advantage of the radiant heat. I'd also like to locate an oven somewhere in my second floor section.
I'll keep reading and follow those other links as well. Thanks again.

Really? That seems low to me I thought it would be hotter than that. I thought it would burn hot enough to stop any buildup from happening.
You know the saying I think therefore I am. Well I have a stupider saying " I don't know therefore I think" LOL I use that one when dummies say I think this and I think that. Caught by my own philosophy.
Diversified Food forest maker . Fill every niche and you'll have less weeds (the weeds are the crop too). Fruit, greens, wild harvest, and nuts as staple. Food processing and preservation are key to self self-sufficiency. Never eat a plant without posetive identification and/or consulting an expert.

Barrel temps, well that's what i've been told. But they don't seem much hotter. An you also have to remember that a rocket doesn't burn all the time clean. At startup it smokes. When you overfeed it too, when you poke the pire sometimes. When there's a gust of wind and it starts to smokeback, well, there's been smoke in the heat riser and tubes before, as the wind slowed the thing down. And the same goes when there's only embers near to the fire going out.
