Joseph Nixon: I believe a longer flue would create conditions for fuller combustion,
eliminating touch of the smoke. I am playing with this myself. Full
combustion is important for me because I plan to be using pellets already
used once in the cat's litter box!
Avery Milieu: I have lived with pellet stoves as primary heat source. To increase the
burn and heat from smaller pellet loads, you need to increase the air flow
to the burn chamber. I shall watch the subsequent vids to see how you
handle the problem.
Marc-antoine Droguet: Bravo
glenn connell: I would have thought the fuel needs to burn before the vertical stack so
that the fire can mix with the fumes when it hits the combustion chamber
before rising vertically, hence the need for a horizontal filler tube
D eez: Try wood chips. Is cheaper fuel. Also secondary burner air holes near top
would reduce smoke to almost no smoke. Thanks 4 posting vid. I like the
square feed tube look over easy to source round pipe.
exclamation3mark: need this with 50 litre water heating capacity for bath added manually by
Apostol Engineering: This means the air is not heated up before is injected into the chimney?
Jay West: Good job on that stove. Subscribed and liked. Godspeed
lebammabel: Yes I used something similar to vermiculite which translates as slag or
dross. I mixed it with heat resistant or stove clay. I must say that it is
not best choice for portable stove but at that time I did not find anything
better. It appeared to be too heavy and stays hot long time after burning.
Good choice for heater. Next time will try something like stone wool.
Apostol Engineering: Very nice!
lebammabel: Size of flue or chimney I chose intentionally. As I understood from
research it has to be even bigger in anent to fuel feeding tube. Now I will
try to increase air flow and see will it change anything.
linuxxxunil: youtube.com/watch?v=vtR6nu2pqE0&feature=related this guy explains the use
of stretched steel for the pellets. no smoke practically.
lebammabel: Just choose right match.
Apostol Engineering: I remember now you wrote to me about the 45 degrees burning chamber. I
believe I was one of the first to make the rs this way. I used to have a
youtube channel called bs4872. Your stoves are great. I have a question, do
you have any insulation in there? Thanks.
lebammabel: If you mean side holes which appeared in stove update - I inserted tubes
which connects outer stove body with chimney. And some air goes through
additional air intake beneath fuel feed tube (square one).
elhigh: For homebrew, this is a really clean, well-thought-out looking build. Looks
great. I burn pellets sometimes, in a homemade basket in my woodstove. It
gets the job done. I second the others who said you need a taller/narrower
flue to provide a stronger draw.
Apostol Engineering: So the air is passing through the insulation in order to reach the holes
you made into the chimney? Is this true?
Fabrizio Milia: That definitely demonstrates that is possible to light a fire with a match.
exclamation3mark: great piece of kit
lebammabel: In this video stove doesn't have the secondary air intake. However extra
air could flow into burning chamber through ashtray opening, but then ash
removal will be quite uncomfortable. The secondary air intake I made later.
You can see it in video - DIY rocket stove - gravity feed (update).
Terry Dosher: could I put a smoke stack and use this in a shop?
lebammabel: Updates 2 and 3 of this video I think are a bit nicer. Here I have some
combustion problems which seems to be solved now.
yutjub123: where is the secundary air intake?
Habagatstove: nice design
lebammabel: Thanks. i have already made some changes. Will upload soon.
lebammabel: Air enters space between both chimneys at the level of burning chamber and
while travels up to holes gets some preheat.
lebammabel: I think it is possible. Some heat will be lost in stack but it still should
bee usable for cooking.
metzindustries: your flue needs to be longer and maybe a bit smaller to get a better draw,
otherwise a nice design. looks stable to put on a pot
