Kelley! Are you out of your mind lol

I have to say I’m definitely in on everything you said except the communal thing. I like my real seclusion and the ability to acquiesce with nature and a beautiful woman hehe

Anyway, I’m definitely looking to build and retire or retire and build so let’s talk  
Mary,definitely looking for a woman to homestead with and long term too. Just putting my hat in the ring here lol
I’m 60 years old look 45 act 20 looking for a ruff and tumble woman who is looking for a man to homestead or live off grid.

Prefer Eastern Tennessee but open. Message me

I built a rocket stove, tried to vent it out my basement window (BIG MISTAKE) Yes! it worked great when it was rocketing! But while trying to get it going and when it quit, blow back massively into my basement! I have since figured I will patch into my chimney, this way when I am starting the stove and when it slows or stops, there will still be a draw and no smoke will fill my basement (wife was pissed)
I built my stove with 55gal drum, refractory cement, galvenized exhaust connected up to my cermamic chimney. Time will tell

All good points guys!

Did some searching on drafting issues with rocket stoves and came across this exerp... verry interesting!

ROCKET STOVES – CONTROLLING DRAFT
http://stoves.bioenergylists.org/stovesdoc/Ogle/stovedraft.pdf
(Variations in chimney height and air flow
openings in a modified “rocket stove”.)
by Damon Ogle
CONCLUSIONS AND RECOMMENDATIONS
Controlling draft at the exit point of a “rocket elbow”
is much more effective than trying to do so
from the point at which
air enters the elbow.
It is possible to produce high temperature exit gases (above 1200 F) and maintain their
temperature through the length of a long combustion chimney.
High temperature and “dwell time” by themselves
are not sufficient to produce dependably clean
combustion. It may be necessary to further mix the exit gases (either by turbulence or by other means) in
order to aid combustion in rocket stoves.
Higher temperatures and cleaner burns are sometimes obtained by partially blocking the flow of
gases through a rocket stove. It may be possible to use mixing devices or jets of air to achieve this
blocking effect and improve combustion at the same time.

Ok so bring the feed and combustion chambers to 6" and go with 8" exhaust pipe? Not sure that will fix backdraft but it does rocket as is...

Looking into 6" chimney liner to vent stove and hot water heater. Just not sure of moisture in chimney?

Thanks guys!

I used perlite in the refractory mix which is still moist, so just did a couple short burns.

I did cut off the intake 4" supply and narrowed the feed chamber and it did rocket very well. Before starting the fire there was serious backdraft.

Guess I'll have to go with a chimney... Thought I could avoid it but way too much backdraft.

Guys,

Did my research and built my stove with refractory and perlite. About a 7" burn stack with 1 3/4" gap from barrel head. It's in my basement so 6" pipe vented out an old window to 2' above ground level.

First fire had serious backdraft before it started to rocket. As the fire died down, I had black smoke bellowing into my basement. Wife was not happy and I was very sad after all the work I put into this!

I read you could have a vertical vent, so wtf happened!? Also, if I don't open my exposed basement door, I get no draft.

Oh! Had an old 4" dryer vent I'm using for supply air, also have clean out opening in front of feed chamber now covered with Fire brick.

Any suggestions on draft other than a 50' chimney will be much appreciated!
