He did build a bigger fire at the end to get more heat into the system. Did it have less smoke when it was a smaller fire with the dry wood?

@JDubyafoto Год назад

I'm thinking the only thing you could have done that would improve the performance of your fire pit is more depth. The Solo stoves are much smaller in diameter than your fire pit and they are taller in height. That gives much more space for the air to really heat up as it rises from the bottom to the top of the air channel. Great video! I know I learned a lot by watching it.

@Fixthisbuildthat Год назад

thanks! definitely would be better taller

@dwaneanderson8039 Год назад

A taller, narrower pit also concentrates the heat more. You want maximum heat and oxygen to maximize combustion.

Yes, and the fire needs to be big enough to really heat the wall of the fire pit. This makes it so the air gets proper flow and is superheated so it really combusts the smoke. I own a solo stove and it works really great, as long as you keep it properly fed. When it's really hot it burns green wood mixed in without any smoke.

0:27 fun fact! (Assuming you don't say it later) the reason smoke seems to always be blowing into your face is because of convection. With nothing obstructing the air's movement toward the fire(and no wind) the smoke will rise straight up. BUT! since there is often a person or group of people somewhat clumped together around the fire, the air that would come from behind them is slowed meaning the air on the other side of the fire that isn't slowed will assert more force bending the convection current and thus the smoke towards the people blocking the air. Of course with the wind blowing the smoke will follow the wind but still be affect by the convection

@annburge291 Год назад

Really liked your pit design. There is another way to have a less smokey fire. You don't construct a tipi. Instead you pack in tightly the logs at the bottom. You add smaller pieces and at the top you construct the twig, pinecone, dried orange peel pile. One lights the top, not the bottom. The fire burns gradually downwards but having the fire at the top means it burns the gases coming out of the gradually heated logs. Much less smoke and significantly more heat.

@robertmosier6028 Год назад

Tip for calculating the airflow: Measure your 4 gaps in the bricks. That's the surface area of the inflow. Ideally the outflow should be similar in size to the inflow, or slightly larger. Number of holes * pi * diameter is the surface area of the exhaust. Compare the two numbers and then adjust the hole size (or number of holes) until the inflow area matches the outflow.

@PBTophie Год назад

Would you want the airflow to be the same between the top and bottom? Would it not eventually choke the fire if the bottom weren't receiving more air to feed it? Or would the heat of the fire just naturally pull in more air from the bottom regardless; provided the holes weren't smaller and/or less numerous than the top holes.

@brucechristensen 11 месяцев назад

Surface area of the exhaust = (number of holes) ⋅ π (diameter / 2)² (Number of holes) ⋅ π ⋅ diameter would give you the total circumference of all of the holes, not the total area.

@johnsmithfakename8422 Год назад

There is one detail about fire pits that people keep forgetting. If the fuel (firewood) is higher than the secondary holes, the secondary burn will become a primary burn for said wood and thus produce smoke. If you want to keep your current system then do not build the fire higher than the secondary holes (maybe an inch shorter). If you are going to mod the system, add a 4th layer of stones and keep the firewood below the holes.

@bumboclat Год назад

What you tried to build is a gasifier stove. However, that design relies on two things: small enough diameter to heat up the walls, making the secondary air rise up by draft, and small enough diameter to deliver that air into the flames. It's not really well suited for a large but flat firepit, but kinda works if you make the fire crazy big, as seen.

@RaspK Год назад

I'd argue that one thing the pit would benefit from would be for the bottom airflow to come out from _under the logs._ In the current iteration, it just tries to get to the flames from the sides, which is better than trying to enter from the top, but you still get convection pushing most of it upwards, rather than allowing it to get near the actual fuel and thereby replenishing the oxygen levels more effectively.

@kathybramley5609 Год назад

Yeah, I was just writing about diameter/height ratio - and drainage: seems likely to collect water when it rains, and moss and a little ecosystem! The DIY double skin drum I saw on here before I saw the solo stove advertising everywhere - that had legs built from the base of the drum. Rocket stoves have built in thermal mass and, like, hardcore substance - as do pizza ovens. Which is kinda what you want in a garden feature. Even though the solo stove looks very futuristic, it's not everyone's vibe and it probably dents and tarnishes as much anything else. And a drum is already a relaxed & utilitarian DIY vibe. Not pretty.

@vmr6771 Год назад

I believe the main reason it took so long was due to the size of the pit. The ring needs to be hot enough and the flame needs to be near the gas plume to ignite.

@court2379 Год назад

The smoke (carbon) needs to burn and needs to be very hot to do so. He had to get a good bed of coals that covered the whole ring and keep a larger fire to get hot enough. If he put a ring on top that narrowed the opening like the commercial units it would be easier to get to temperature. It pushes the heated gases together to address potential cold spots in the flow and reflects much of the heat back inside. Also notice they used stainless steel. Those temperatures will corrode the ring and cover out relatively quickly with regular steel or cast iron.

@chrisdunfield513 Год назад

One suggestion I would make to reduce smoke, indoors or out, is to build an "upside down" fire. Put the biggest pieces on the grate, on the bottom, then the next smaller, at a right angle to the biggest ones. Keep alternating layers, leaving some space between the pieces for air, then put newspaper and small kindling on TOP, NOT on the bottom. You may have to feed a bit more small kindling at first, but not for long. You will be amazed at how much cleaner, quicker and hotter the "upside down" fire will burn. Each layer heats the layer below as the fire goes DOWN (trust me, it will, even though fire generally does go up), so each successive layer burns readily, and there is hardly any smoke. When you make a fire the usual way, the bigger wood on top isn't hot or dry enough, so there is quite a bit of smoke until the big pieces get going. Once the "upside down" fire gets down to the bottom layer, you just feed it more wood on top as usual. If you try this method once, you'll never go back.

@gooeytarballs Год назад

I think your Math's off a bit. In 24 hours we would not have but twelve or so of 'daylight' and fewer of the sort of light seen in the video clips. Lets say, ten hours or 600 minutes MAX. Allowing for time to load the pit, start each fire and get a respectable burn going would consume not less than ten minutes per instance (in a dream world perhaps), leaving but 130 minutes for the forty-seven video clips or 2.7 minutes per clip. The first fire and smoke (edited) clip ran a minute twenty plus with several obvious cuts/clips cobbled together along with some quite rapid talking. Let us assume it took significantly longer that 2.7 minutes to film that first clip. Now, between takes, we need to cool the pit down to remove the ash and such and reassemble things, add combustibles, ignite, etc. Then there is all the work to perforate the ring - not starting fires then, was he? Not sure where he lives in TN, but outside of town with a few acres, folks don't pay much attention to their neighbors - esp if they have Cable and Internet and a place to take care of or a job in town.

I appreciate seeing the principles as they are demonstrated in this video. I not only see that the design works, but I also see how and why it works. Now I understand better. Thanks.

@xSKOOBSx Год назад

I think the next step in efficiency would be to add spiraling channels around the outside so that the air in the walls of the fire pit can't just go straight up, but has to go at like a 45 degree angle around the outside, increasing the time it spends in the wall and therefore the time it spends heating up. This would likely result in a secondary burn happening sooner after starting the fire, and a more complete secondary burn due to potentially increased velocity.

@bawfuls 10 месяцев назад

Another feature to help secondary burn might be to add a lip above the top holes, as is seen on the retail fire pit design he's imitating. This would force the air exiting the top holes towards the fire a bit before it can rise above the firepit, along with adding some radiative insulation to that region to help keep temps up and maintain the secondary burn

@chuckloya5067 Год назад

I really liked your video, I've watched many and this video was the best. I loved how you actually tested the different size holes until you got what you were shooting for.

@trevorfields5216 Год назад

Great video! I liked it! Here's what you missed when you looked at the patent for the solo stove. The secret of why it generates almost no smoke isn't to do with the size or number of holes in the top/bottom. That is a factor though. The biggest factor is to look at the ratio of the height of the pit to the circumference. Basically, the solo stove is skinnier and taller. With a pit of this diameter, you'd have better performance by building the height of the pit upwards. This increases the effective space of that insulating layer, providing more area for smoke and gasses to slow, cool, get trapped.

Great presentation and great theory vs. practical application. One thing I have experimented with to "control" the direction of the smoke was to use a perforated steel panel and form it into a cone shape, to place over the pit. The conical and tall shape acts as an accelerator to draw more air is and to shoot the smoke up higher, out of your path. It would be cool to see you add that concept.

@russwatson8713 Год назад

It would be interesting to have done a control burn using dry wood before drilling the fire ring holes. This would show how much of the improvement in smoke reduction was due to the modification of the fire ring and how much was due to the drier wood. Great video otherwise. Very easy to understand. Will use your tactics when I build my next fire pit.

@scottchristie Год назад

Great video. However, the part that's missing is the ratio of stove height to diameter. There a powerful convective element with this process you just aren't going to get with such a wide and shallow fire-pit. The point is to increase the secondary burn which takes place at the top of the fire. In your stove the top of the fire (flames and smoke) is already outside of the fire-pit. It's just NEVER going to work like that. You pit needs to be 2 or 3 times higher for that diameter. Notice on the patent how the top is tigher than the rest of the pit and the ratio of heigh-to-width. The secondary combustion has to take place BELOW the top surface of the stove. Dry wood for the final tests but wet wood for the preliminary is also quite misleading. A lot of people will fail following this advice.

If you ever decide to return to this project, you could place a small lip around the top of the internal circumference of the pit forcing the air for the secondary combustion in rather than straight up as it exits the holes while simultaneously trapping some smoke underneath the lip which may increase the combustion but also possibly reduce the airflow. I am curious to see the effect. It's a similar approach the reducing the diameter of the pit without making it look like a soda can.

@rexstuff4655 Год назад

Or, more likely, your original fire was simply too small for the size (and wetness) of the wood you were using. You'll note that in the 'after', the fire is substantially larger than the 'before'.

Pretty sure it would be exponentially better if you placed a another layer of stones on top of the steel liner to add as a "ledge" so that the top opening is a little tapered.

@danmoretti8898 Год назад

Hm probably true, just like the solo stove

@ReeferCheifer13 Год назад

He’s onto something here. By narrowing the top of the fire pit, you will achieve what is known as the Bernoulli effect. A greater force of air thrusting through the whole system, and theoretically more fweefwee

@semaj262 Год назад

When wood gets hot enough in a low oxygen environment, it produces wood gas, which is flammable. Combustion needs oxygen, so you see fire "shooting out" of the vents, which is actually the boundry of wood gas and oxygen mixing and burning. Gas burners have this same boundry flame, but inverted, with a stream of flammable gas into an area of oxygen. Fun fact, the fire we see is mostly comprised of incandescent soot, material that gets so hot it glows like a lightbulb or forge metal.

@Fixthisbuildthat Год назад

wood gas...I like that 👍

@JayDee-xj9lu Год назад

So it's true that wood doesn't burn. It gets hot and produces flammable gas. If you look very close to wood burning there is a slight gap between the wood and the flame.

@Derf1313 Год назад

Correct, if you're seeing flames out of the top holes, it has to be wood gas being drawn into the lower holes, & mixing with the air to then be ignited as it exits, looking like the burner you talked about. Just air coming out wouldn't really do anything... My woodstove has secondary burning, but the flue comes outta the middle of the firebox (damper can be slid open to load wood, so it exits the stove by flue not door, lol)

The fire shooting out of the holes is actually the wood gases burning. Honestly, fire ring is too large a diameter, and not tall enough to create those jets...It takes convection to create them, and the larger diameter keeps that from happening consistently around the ring.

@Fixthisbuildthat Год назад

Yep, exactly what I found. This is pretty much the best you can do with this style ring. But still way better than stock

@EdwardChen0 Год назад

I'm thinking the same thing, a taller and/or smaller diameter ring could work better. Either way, nice testing with the fire pit you already built!

@mikeweckesser4450 Год назад

the smoke is always in your face because the smoke will travel towards the tallest things around the pit. Think of it as smoke traveling up a wall. At one end of my pit I have a tall rock (almost 4ft at the peak) I am not sure the science behind it but this makes the smoke always migrate towards it and then up the rock and up. Just something to think about. great build as usual.

@seanwaite7248 Год назад

Air rises over the fire, pulling outside air towards it. You block that inflow, so rather than it flowing in to the fire it can get pushed out towards you

@tslee8236 Год назад

Yeah, flue effect sucks the air through air speed differential.

@JJ-te6tx Год назад

No your body acts like an air dam. It blocks air from getting to the fire . What creates a vacuum and the fire smoke moves towards you. The more people that sit around you the bigger the vacuum. So sit alone and the smoke will not bother you.

@brentfarvors192 Год назад

@@Dgiztred Yes. My "experience" is exactly as posted; The ONLY WAY to control the quantity of smoke, is to burn on a clear (high pressure), windless day, using the driest and most finely cut fuel available...Using the method posted here will make the fire burn HOTTER (More air flow= A hotter flame), but will do NOTHING for the smoke; Especially when starting the fire, and when it starts to burn out...I've tried with Pits/Barrels, and everything in between; You aren't going to beat physics...

@TheFutureisTheFuture Год назад

I have a different brand than Solo and it is completely amazing. Really cool almost welding type flames coming out of the sides at the inner top and bottom. Some smoke but only on super wet stuff (I've burned mulch). I have 3 problems with the setup. 1) They are all very tall so its not really a firepit feel. 2) they are completely closed in except at the very top so heat is focused basically completely up. So they are not as warm either. 3) wood burns really well and super hot so it also burns fast. It's all very impressive physics and thermodynamics but it does not feel like a campfire pit type thing. Feels very "efficient factory produced fire that can melt metal." haha great video!

@Khaspre Год назад

Good observations. I wonder if it would help to suspend a flat plate above the fire? Theoretically that should redirect the hot air toward the outside of the firepit. I expect that the fire will eventually destroy the plate unless it’s made of ceramic or fire brick or something. And I wonder if a cone sticking out of the middle of the plate might encourage more even distribution of the hot air than only the flat plate. Seems like there should be a way to get the benefit of the efficient, smokeless fire without losing out on the warm, comfy firepit.

@BarriosGroupie Год назад

Yes, the stacking of the wood has more of an influence on the smoke compared to the fire pit's design. What works for me is stacking the wood to create a closed high temperature chamber, like a furnace, with smallish entrance holes for the air, and corresponding exit homes for the smoke.

@owlcricker-k7ulm Год назад

If you notice on the Solostove the top opening is necked down smaller than the diameter of the main burn chamber. That increases the velocity of the air leaving the chamber and this increased velocity produces a slight vacuum in the chamber. The vacuum pulls more air through the secondary combustion holes making a more efficient second burn and less smoke.

@TheHobbyShop1 Год назад

The way you took a scientific approach was great and the colored smoke bombs were a brilliant. Nice work as always. This had to take about a week of experimenting to do all that and I appreciate that.

@user-gn6pt2pp2x Год назад

I enjoyed the pace and your entertaining presence in your video...not always the case with DIY videos. The approach and progression of your testing methods helped me think through the construction and physics of the design. I am working on the final design of the Smokeless Fire Pit being built at our home and I had a few questions about the final specs of the pit you ended up with. As noted by @SmokinOak, it seems that confirming the height of the fire pit, which will require a fire pit ring that is tall enough, may make a difference in the pits ability to heat up the smoke coming out of the top holes. Will you please confirm the height of the ring you used and if you have done any further testing where you tried using a taller ring? Also, in your video, you mention putting 15 each ½” holes spaced at 1.5” apart and then adding 6 holes in the bottom spaced at 3 ¾” apart but I do not believe you mentioned the size of those holes. When examining the images in the video, they appear to be large than ½” holes. Will you please confirm what size those bottom holes are and the height of the fire pit and fire pit ring? It would also be helpful if you provided the weight of the fire pit ring to ensure I get a heavy duty enough ring. I look forward to hearing from you and watching more of your videos. Cameron

@seapanther53 Год назад

After doing this project years ago, what I learned was it's easier to get the smokeless results with a smaller firepit ring. I think this is because in order to get smokeless results you need higher temperatures which is easier to get with smaller pits, unless you plan on burning A LOT of wood at one time. This is probably why the solos aren't that big.

@donoimdono2702 Год назад

@hybredmoon 7 месяцев назад

For that design, smaller fires will be more prone to smoke. That's why the large fire worked better. The fire has to be large / hot enough to heat the air in the gap so that it's primed for secondary combustion when it reaches the holes at the top. For that you either need a hot fire, or taller walls to allow my travel time which equals more heat.

@suckfuldodger 4 месяца назад

yeah I'm looking at that manufactured one and I'm thinking, just taller walls

@RobertCornejo 3 месяца назад

I rarely get heavy smoke with any pit, but it’s because of box fire in conjunction with tee pee style. It creates it own vacuum the hotter the fire the faster it’s heat is ejected along with its smoke. Needless to say, I like raging fires. Fill my truck bed once every two months with good dry wood.

@Tman317 Год назад

Great video and tests! Love the tape idea for drilling, I'll remember that. For my outdoor fireplace, I added a 12V 4" boat bilge blower underground, contained in drain pipe that draws air in from about 8 feet away and exits under the center of the pit. When I need to get the fire going quick, or reduce smoke, I turn that on (hooked up to a 120V to 12V adapter and a smartplug) with my phone app and boom...raging fire and no more smoke!

@mriguy3202 Год назад

I'd like to see a video on that! I've thought about doing something like it for my fire pit. How do you keep water out of the air duct? What did you use for the duct to keep it from decaying from the heat?

@scottsluggosrule4670 Год назад

You will eat a LOT of wood that way. Just make pit smaller so coals air mor in contact and heat that metal more. As I posted above 450F is minimum to get secondary burn.
