DIY Fuel Efficiency Modification for Trangia Spirit Burner B25 | 瑞典Trangia B25酒精爐效率優化

[@maradall]

What I would like to see: a comparison of water boiling times!

[@thermalreboot]

You should do the test again, but with 2 cups of water in a pan on each to see how long it takes to boil. You've demonstrated that your modification will allow the stove to burn longer, but at what cost? Does it result in a cooler flame? If your modification can bring to a boil first then you've proven real efficiency.

[@horustwohawks]

Blue flame is hotter and more complete burn (fuel efficiency).

[@thermalreboot]

@@horustwohawks prove it

[@horustwohawks]

@@thermalreboot Point taken -always best to test one's self. My remark is simply based on general (some scientific) information gathered about alcohol burning, and not on my own experience, and it is true that real life tests can and will differ based on any number of variant/influences.

[@XShadowAngel]

@@thermalreboot It's factually correct. A flame burning blue is burning at a higher temperature than one burning yellow. Yellow flames are cooler. It's just facts. Google it.

[@thermalreboot]

@@XShadowAngel Thanks for the hand waving.

[@dominolastley1754]

I ran this test with a couple of Trangia TR-B25 spirit burners. One TR-B25 was modified as per the video. The tests were run using a Trangia 27 storm cooker, a stainless steel kettle, 550ml of 66F water, 30ml of alcohol per run. The water was brought to a boil (time recorded), and then left to burn until the flame was gone. The unmodified burner boiled the water in 5:40 and continued to burn until 9:05. The modified burner boiled water in 7:40, and continued to produce useful flame until 14:45. Observations: The modified burner produced a hot blue flame immediately. The unmodified burner burned more intensely (blue, yellow and orange flame), heating the water more quickly, at the expense of being less efficient in its burn. My overall conclusion is that the modified Trangia TR-B25 burns less intensely, but burns the fuel more completely, thus using more of the total energy available in the fuel. The tradeoff in boil time is a compromise I'm more than willing to accept. I tend to use my Trangia for cooking more often than I use it specifically to heat water.

[@orraman5427]

The Trangia comes with a device which will reduce the heat output and increase burn time; it's called a simmer ring.

[@DoNotPushHere]

Ia that the lid with rotating plate? I always wondered how it was meant to be used...

[@leeknoz935]

i wonder how it would do using the simmer ring also

[@pertwee9376]

The much bluer flame on the modified version tells you that more complete combustion of the fuel is happening, which should obviously lead to better efficiency as well as less sooting on pans etc.

[@peterplaskett4958]

According to Google a blue flame is the hottest yellow is the coolest,, I remember this from using Bunsen burners many many years ago

[@ConstantinDV]

Curuosity and human ingenuity are to be praised even if one can think of an improvement. I bet that half of the commenters suggesting better ways to test, never tried to improve a thing in their whole life. How about a little humility and gratitude to those who do? Great video! Steps clearly explained, burn compared in similar conditions. Blue flame is whzt you want. It is the cleaner amd more efficient burn. You want to see a water boil comparison? Politely ask for one!

[@MrTangent]

I would like to see follow up video comparing the unmodified and modified boiling 2 cups of water test, please.

[@randomactsofcooking]

Yes, please do a water boil time test. Also I think the burn time will change with a pot on the burner. Thanks.

[@MrTauron77]

Zseniális megoldás, alkalmazni fogom, végül is már egyszer bevált a hamutartóból készült alkoholos főzőnél ami csak 9 percig működött.

[@perrycoate5016]

My guess is that boil time takes longer, but fuel consumption is reduced allowing you to carry less fuel which helps offset the relative higher weight of the Trangia compared to other stoves. Nice video. Thanks for sharing.

[@mclostinthewoods]

I guess it depends on what you plan to use it for. If you want to cook with it, that may be beneficial (although the simmer ring provides the same benefit). However, if you're just boiling water, I see the unmodified stove being faster. Its flame output was much more vigorous. The modifies stoce may butn longer, but the flame is lower, meaning lower temp for the pot.

[@QUADBOYification]

The science is important here, this specific burner type has a double wall (small slit on the bottom) and heats the fluid to boiling boiling to gasify faster. This creates the jets. In fact most of the heat comes from the big flame in the middle. The trick is bringing the heat back into the middle, not the sides. This works with air but not a fluid. A real gasifier has a double wall with holes on the bottom sides. and a couple of mm down the inner top, directing the airflow back into the middle downwards. Wood blocks will be gasified and reduced to white glowing ashes very efficiently. To enhance this process a little fan is placed beneath the double wall bottom and (turbo) inserts air into a hole increasing the heat. You can make these gasifiers with standard double wall stainless steel or titanium cups (300 ml) easily. The difficult part is to drill tiny holes into the sides just above the bottom. Piercing it first with some tool is required. If you really want an improved version of the Trangia you just place a small cup with alcohol or denaturalised spirits inside the gasifier just explained above. It will boil water in 3 minutes. Basically (what I am saying) this classic Trangia design has flawed and should have had holes on the inside just beneath the top., idealy directing downwards, heating the fluid with jets of heat. This increases the heat violently and reduces the irregular flame dancing around. It will of course burn for only 5 minutes.

[@goyo777]

I wonder why they use both steel wool and carbon felt.

[@ΝίκοςΛιόλιος-ε6ξ]

Blue flame means higher efficiency (I know from cental heating boilers). So even if output power lessens you take more btus or watthours from the same fuel quantity. Bravo!! Worth trying. Perhaps there is also no need to dilute with water to get rid of shoot (usually yellow flame gives shoot) so you take even more btus. Also less accidental spillage.

[@norwegiangadgetman]

Yes, blue means a more complete burn, but if the stove at the same time only allows half as much fuel to burn as usual, it may not produce the same amount of heat energy. We need to see how fast it boils a cup of water, or with a large post of water, see how much more it can heat the waterbefore running out of fuel.

[@TheRealGundalf.]

well.. you reduce the heat output to extend the burn time... that means that your water will take more time before it starts boiling and in that longer time you will probaply burn the same amount of alcohol as with the standard burner. On top there is the downgrade, that the additional material takes some volume. So the maximum amount of alcohol inside the burner is reduced by the volume of the steel wool etc. all together not a good trade off imho....

[@walterhoch4011]

Я не специалист ,но думаю - Не факт ,что тепловая мощность уменьшается из за меньшей подачи топлива. Она может оставаться такой же или даже быть больше из-за лучшего подключения кислорода в процесс горения. Об этом говорит голубой цвет пламени. Почему ни кто не говорит об ещё одном преимуществе- отсутствие копоти.

[@nikondgo]

Nice work!. But as many others said it would be important to see if there's a difference in the boiling times. They do seem to burn somewhat differently, at least part of the time. If that blue flame is a consistent feature, that would be nice - more efficient burning, less soot. Your mod seems to bring more burning surface at the same level as the jets by wicking alcohol to the surface, which probably reduces the pressure in the jets. That turns Trangia into a more of a surface-burning stove. Interesting, not sure how useful. All that said, the only reason for me to drag around a Trangia set or a burner would be if I'm on a trip where weight doesn't matter much - canoe, cycle touring or car camping. And then a slight difference in the fuel consumption wouldn't matter, as I'd have plenty of fuel. When hiking I wouldn't bother with Trangia at all - there are much lighter options out there, doing the same job. Don't get me wrong - I'm a big fan of Trangia, It's unbeatable for cooking in the wind and for longer base-camp style trips, but it has it's limitations.

[@ernieschatz3783]

Not "doing the same job." With the Storm Cooker, wind is not a worry. This is not true for lighter weight setups...including gas.

[@williamli8708]

give it a shot, mod it - since it doesn't permanently affect the trangia - test it out

[@jimbojet8728]

A bit of a no brainer there? The ‘modified’ has a much better burn, I’d be happier with that neat blue flame every time. Then the burn time is much longer too. Of course there is the question of which flame will be the hottest , so perhaps a boil test is required and to reduce the flame there is a ‘simmer ring’, supplied. So, some great innovation here, but it may be to solve a problem, that doesn’t exist. Great fun though, an interesting vid. Thanks.

[@taber247]

Pity you did not test them under working conditions ie Boiling Water. As the pressure of a pot over the flame would change the characteristics. Thank you for sharing Take care

[@BikeNCamp]

Yeah, it definitely came across my mind, but as I was filming this video, I didn't have the setups to really compared the stoves side by side. 😫

[@victoryfirst2878]

This is one cool test fella. What I am wondering if you could do a test with kerosene heaters and make a stainless circular mesh chimney inside the top part of the unit ?? I bet this would happen to the kero heater too. Maybe a video Sir ? Thanks

[@hArtyTruffle]

Looks like the modified version is burning hotter too. I’m guessing it will bring water to the boil faster. Great tip. I’ll try that too. 👍🏼

[@carina2978]

這是去年我看CCLand 小島的影片內容 還買了他們家的材料包 實際使用效果很不錯 是個很好的創意，您這影片內容怎麼完全一樣 XD

[@thomasmusso1147]

👍👍👍 .. very nice .. thank you for sharing. I've been 'mulling' 🤔 for some time now over doing something similar with my Trangia. I have done this with most of my other home-made Alcohol Burners. It also reduces the hazard of fuel spillage. Will definitely give it a go .. take care ..

[@wordwalker3]

*-10 months and NO follow up video?? Wassaaaap? You are not proving much of anything without testing it's effect on actual boil time!! So much for the scientific method!😮‍💨

[@markperry222]

The real measure of efficiency would be to see how many grams of fuel must be burned to boil a quantity of water. Your modification does have a couple of benefits though. First, as someone else mentioned it reduces the risk of fuel spills if you knock the burner over. However, I have never done that, I guess you would need to accidentally kick it. Second, if you are burning 95% alcohole the flame can be very hot, sometimes too hot and slowing the burn will make things more controllable. I have noticed that if I burn 95% the simmer rings fails to snuff the flame as the alcohol is varporising too quickly and is blowing through the simmer ring. I am guessing your mod would fix this problem.

[@BIGMC1300]

I wonder what the max volume of fluid will be in the modified version ? A standard Trangia burner holds 100ml I believe?

[@MIKESWILDWORLD]

I like your video. The more efficient blue flame should work better, however a boil test would be necessary to dispel the non believers.

[@tornagawn]

Blue flame indicates complete combustion. The yellow flame is caused by Carbon from incomplete combustion, this is not only less efficient but leads to Carbon build up on the pans and burner.

[@Trains-With-Shane]

Very interesting modification. As others mentioned I'd also like to see the practical application test visa vis a water boil.

[@AhmetCakr-BURSOF]

Wrap the metal filter with the help of a wood without cutting the metal filter and then place other materials inside. it will work more efficiently. the heated metal will vaporise your fuel by transmitting the heat to the al regions. my guess is that it will work more efficiently. I like your work. I will experience it.

[@waynehwlam]

From my experience in building alcohol stove, it is futile to try besting the overall real world cooking performance of the stock Trangia stove, which is extremely well tuned and fool proof under wide range of condition/ambient temperature; it just works great! Trangia’s only downside is the weight (compare to homemade soda can stove).

[@mo-reesespieces9066]

How long will the stainless steel last? The black plastic looking stuff attached to the aluminum foil, is it toxic? Will the insides need to be replaced after a specific period of time or usages? Very interesting test. Thanks for sharing. Peace

[@kev5949]

so many people making comment about boiling times blah blah blah, when the massive difference is clearly the blue flame, cleaner burner = less soot

[@BingoBongoMan]

While everyone is engaged in discussions about water heating tests, what really catches my attention is the pure blue flame, signaling enhanced efficiency and notably without the irksome soot.I'm also curious about why fire cotton and steel wool are used beneath the mesh at all! I can't help but wonder if it might be more prudent to use stainless steel wire wool, given that the non-stainless version tends to corrode severely when exposed to water or oxygen in general. I'm sure that the heat produced in a stove only accelerates this oxidation, and it likely wouldn't be a pleasant sight beneath the fire cotton in this setup after just a single use. Opting for stainless steel wire wool might be the more sensible choice. Still, I'm uncertain about the precise reason for using wire wool and fireproof cotton! Could it be to establish a more uniform evaporation surface in the fuel pit and also to slow down the combustion process? What would actually happen if you were to use Platinum Embers instead of fireproof cotton? Theoretically, this could lead to an increase in the chemical reaction and subsequently, the heat, wouldn't it?

[@agesadventures]

This looks interesting. It would be good to know how it does for boiling time. Thank you for this and it certainly is something to try😊

[@markraciborski4289]

Is there a reduction in sooting up a pot? A test of water boiling? I would think so, less yellow flames?

[@bannedagain.8334]

I've seen a lid over the big hole in the middle so it only burns from to holes around the rim..the jet holes..

[@davidlee6461]

[@Jens-tc5yz]

Mycket bra... från Sverige ❤

[@shoucho5124]

I will go for this for the cleaner burn, so I can use safer 90% alcohol without much soot build up. Do not thing the boil time make a big difference in actual usage.

[@alanbateson9275]

I can't help thinking that Trangia, as the market leader in these type of stoves would be producing them with this modification if they deemed it an improvement.

[@raymondparker1110]

Yes, but at what cost ? I'm sure Trangia would include modifications such as this if they thought the general public would pay the increased cost of such modifications. Like most things, the bottom line P&L figure dictates these factors.

[@nikondgo]

I wouldn't hold my breath... Trangia being a market leader is a bit like Apple - they always know better then their own customers... Example - why don't they use the wire fold-out handle on the simmering ring, which is a standard on all knock-off Trangia-style burners sold on Amazon? It's far more convenient. I've done a lot of cooking on Trangia when the simmer ring is essential. I replaced my original Trangia burner in my Trangia cooking set with a knock-off long time ago and can tell you they burn exactly the same. Also the knock-offs are 15g lighter... Why not implement those obvious improvements? Costs money and will change little in terms of revenue.

[@kd4301]

Is there any risk of explosion after modification?

[@DansTrangia]

Respectfully, this doesn't appear to be measuring "efficiency," which would be the number of BTU's per measure of fuel. This appears to be measuring burn time. Given that the Trangia burner already comes with a simmer ring that extends burn time longer than this test, I don't think any conclusions can be drawn from this test.

[@LokYourDoor]

Why it burns longer?

[@edwarddeleon975]

A great video and a side by side demo thanks for sharing

[@Daz555Daz]

This shows it burns slower. For a measure of efficiency we need something like time to boil a set volume of water.

[@litrick5471]

[@jerryseymour2738]

Isn't galvanic corrosion a concern?

[@yefroy]

[@Saltfly]

Noticeably less heat coming out of the jets on the modified.

[@taber247]

Space Heaters? Do the comparison under normal working conditions, eg boiling water.

[@BikeNCamp]

It does. What I should've done is to include a part of the video with water boiling test. But since I don't have two identical stove mount for the comparison I figure I'll just skip it.

[@perandersson7019]

Simply do two tests then and just shift and compare end result Would be interesting to see.

[@markraciborski4289]

How does it perform with a simmer cap, say at 1/2 open?

[@ometec]

This can burn hot enough to damage the seams of the spirit burner.

[@juslitor]

As could be seen from the video, the maximum output is somewhat lower. Also, considering that the trangia has a simmer ring which works very well, this mod doesnt really make that much sense.

[@mastedi]

Thank you. I am convinced!!

[@morris4069]

Might want to play with making your own stoves n learn that longer burn doesn’t mean better. You’re looking for a balance of burn time and heat output. The Trangia has been around for a long time for a reason and the only hotter stove I’ve came across is the Evernew Ti stove. Both have their advantages so one is not really better than the other.

[@neologian1783]

Did you ever get round to a side by side boil test? As has been mentioned.....longer burn time, in and of itself, is not necessarily an indicator of greater fuel efficiency. The bluer flame on the modded Trangia is promising but the real test would be comparative boil times + remaining burn time.

[@Sokol10]

See this Lifestyle CC Land video with similar modification and boil comparison - has English captions: 【原創藍火設計】為何眾多手作職人追求終極藍火? 好處這麼多!! Trangia藍火風暴值得你瞭解!! With modified Trangia the time to boil increase, but the fire duration increase too, with less soot in the pan.

[@rewardsoverwater7821]

Has anyone tried to put a round piece of metal smaller than the diameter of the stove after it gets hot, which allows the heat to be placed on the burner hole and make it hotter?

As a wick, you can use the toilet paper or the cloth (I use my ex bluejeans). I made the stove by my self, using tuna can 120 gram. First, I put a wick (seven layer of my bluejeans) in the bottom, then a steel wool after. Finally, I covered with the wire mesh on top. For boiling or cooking, i need my Potstand for sure. I'm very happy with my DIY stove, because with 40ml of methanol, I have the flame for around 50 minutes. And... I think if I use the simmer ring, the flame burn out (probably) for more than 1 hour (unfortunately I don't make a DIY simmer ring yet). You can try to make your DIY Stove (like mine). It's very easy to make it. And it's my favorite DIY stove.. ever... 👍

Unless you actually boil water and compare the times & quantities, you have no way of knowing if it is more efficient. It's quite possible that all you did was slow down how fast the modified stove burns through a set amount of fuel. A waste of time, since the Trangia burner already has this function. Try it again, this time with more water than can be brought to a boil, several liters maybe, measuring initial temperature and final temperature. Rinse & repeat several times to make sure there are no oddball outliers.
