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.
@@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.
@@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.
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.
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.
*-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!😮💨
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.
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.
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
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.
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.
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.
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.
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....

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
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.
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!
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.
👍👍👍 .. 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 ..
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.
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.
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?
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.
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
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).
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
Hi, The wire wool and carbon felt displace the amount of fuel that can be accommodated within the burner. How is the burn time affected by the reduction in capacity compared to a fully filled unmodified burner? Thank you and kind regards, T😊
@@CoastGord Thank you kindly for your reply. The reduction in capacity of fuel caused by this modification will offset any gains in fuel loss through 'evaporation'. I respectfully believe your proposal is flawed.
People are ignoring the fact that the modified Trangia had more of “BLUE FLAME”…..I don’t think you know that a blue flame is also a hotter flame…it boils water quickly….since you can close the Trangia with fuel inside, it makes this much more efficient for boiling or quick heating of food…
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... 👍

I don't care what modification you make the energy density doesn't change it is and always will be 21.1MJ/L. So you haven't improved efficiency you've merely slowed the burn rate.
Yes .. the heat output is probably reduced somewhat. However, looking at the flame colour, the modified stove appeared to have a more efficient burn. One doesn't have to be an Einstein to figure that out .. basic physice. I learned that back in 1963 at age 13 in my school science class.
This mod increases burn time. And given they burn too hot for most cooking applications , boiling water excluded, the Trangia is now more efficient for cooking by operating in a more usable heat range, for longer.
@@flyingtigers7856 I agree and not mention when you’re out and about having to allow extra time for the burner to cool down. Eventually the burner will produce hairline cracks over time.
A lower heat output for the Trangia is not a bad thing. Mine, especially when a windscreen has to be used, often burns too hot .. even with the simmer ring. A longer, gentler burn for me, is preferable, especially when cooking and not just boiling water.
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.
Iv looked at this and see what's happening see you put material in and it soaks up more fuel ⛽ so in the long run your not saving any fuel because it takes more fuel to fill it so there ya go don't get me wrong the gauze you put at top is a great job because saves shit from falling in 👍
Danny .. No. He put exactly the same amount of fuel into both stoves .. 30ml if I'm correct. Also, the modified stove will take less fuel .. the material in it takes up space .. volume.
@@thomasmusso1147 with him using a a material would soak up fuel up it would not last longer because its the same amount yes he said he used the same amount but this would not last 5 min 30 sec longer trust me its not the case
He used 30ml in each one. The carbon cloth etc. Reduces the amount burning from the middle which saves fuel. I was concerned that it would impact the keys since the heat is needed to vaporize the fuel for the heat to work. It did take a bit longer to prime but seemed to be efficient still. I agree a boil test would be good to see how it compares.
Given that the laws of thermodynamics state that energy cannot be created or destroyed, what you have done here is prolonged the time it takes to to burn a given amount of fuel by decreasing the burn rate and btu output of the stove, thus crating a less efficient stove that will take longer to cook or boil anything you put on it.
Modified is less hot than unmodified... orange flame, blue flame, white flame? Which one is hotter? The white the flame rhe hotter.... orange means more toxic and less temperature of the plasma o flame it also means burning the fuel faster.

Ia that the lid with rotating plate? I always wondered how it was meant to be used...
i wonder how it would do using the simmer ring also
According to Google a blue flame is the hottest yellow is the coolest,, I remember this from using Bunsen burners many many years ago
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.
I would like to see follow up video comparing the unmodified and modified boiling 2 cups of water test, please.

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

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.
Noticeably less heat coming out of the jets on the modified.
A great video and a side by side demo thanks for sharing
Is there any risk of explosion after modification?
nice mode!
question any link for this fire retardant cotton tape?
I'm thinking if the manufacture could improve efficiency, they would have already.
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.
How does it perform with a simmer cap, say at 1/2 open?
This can burn hot enough to damage the seams of the spirit burner.
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?
Isn't galvanic corrosion a concern?
Cool good job 👍
Still the same amount of BTUs just at a slower rate!
I think a real world test in the wind with two pots of water is required.
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.
Thank you. I am convinced!!
Why it burns longer?
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.
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.
See this Lifestyle CC Land video with similar modification and boil comparison - has English captions:

With modified Trangia the time to boil increase, but the fire duration increase too, with less soot in the pan.
Hi,
The wire wool and carbon felt displace the amount of fuel that can be accommodated within the burner. How is the burn time affected by the reduction in capacity compared to a fully filled unmodified burner? Thank you and kind regards, T😊
Reduces evaporation
@@CoastGord Thank you kindly for your reply. The reduction in capacity of fuel caused by this modification will offset any gains in fuel loss through 'evaporation'. I respectfully believe your proposal is flawed.
@@my_handle.... this is how we learn 👍
@@CoastGord 👍
Interesting.
but what with boiling time???
Does the steel wool ignite if you skip the fire retardant fabric? That could be a really hot topic!
I predict it will not due to the mesh.
People are ignoring the fact that the modified Trangia had more of “BLUE FLAME”…..I don’t think you know that a blue flame is also a hotter flame…it boils water quickly….since you can close the Trangia with fuel inside, it makes this much more efficient for boiling or quick heating of food…
is it reuseable or we have to put new foil everytime?

請問這個小片的不鏽鋼網要去哪邊買？
Genius!
Can i use a fire rope instead?
I've never tried fire rope. If you do try it, please do share your findings with everyone.
Have you considered replacing carbon fiber with fiberglass?
Wish I had that felt, where can I find it please help
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... 👍
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.
I got mind in 30 minutes
哇！哥這個是小島套件嗎？效果好棒喔！
Blue flames are hotter than yellow...so you can judge by that
I don't care what modification you make the energy density doesn't change it is and always will be 21.1MJ/L. So you haven't improved efficiency you've merely slowed the burn rate.

wow you just reduce the heat output , yiu realy mr. einstein
Yes .. the heat output is probably reduced somewhat.
However, looking at the flame colour, the modified stove appeared to have a more efficient burn.
One doesn't have to be an Einstein to figure that out .. basic physice. I learned that back in 1963 at age 13 in my school science class.
This isn't so much about burn efficiency as it is burn rate.
reducing burn time doesn't mean more efficiency, all you have done is reduce heat output
This mod increases burn time. And given they burn too hot for most cooking applications , boiling water excluded, the Trangia is now more efficient for cooking by operating in a more usable heat range, for longer.
@@flyingtigers7856 I agree and not mention when you’re out and about having to allow extra time for the burner to cool down.
Eventually the burner will produce hairline cracks over time.
the steel wool and the mesh also helping by radiate its heat to the pot
A lower heat output for the Trangia is not a bad thing. Mine, especially when a windscreen has to be used, often burns too hot .. even with the simmer ring.
A longer, gentler burn for me, is preferable, especially when cooking and not just boiling water.
Modified version appears to burn with a much cleaner blue flame so perhaps no carbon deposit?
請問您使用的燃料是？
我是使用工業酒精
Only thing I can see the benefits for this hack / modification is if it ever tipped over. The BTU IS MASSIVELY affected
When you give a simple job to college grad!
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.
You obviously have no fire alarm !

isnt a blue falme colder, which takes longer to boil
Iv looked at this and see what's happening see you put material in and it soaks up more fuel ⛽ so in the long run your not saving any fuel because it takes more fuel to fill it so there ya go don't get me wrong the gauze you put at top is a great job because saves shit from falling in 👍
Danny .. No.
He put exactly the same amount of fuel into both stoves .. 30ml if I'm correct.
Also, the modified stove will take less fuel .. the material in it takes up space .. volume.
@@thomasmusso1147 with him using a a material would soak up fuel up it would not last longer because its the same amount yes he said he used the same amount but this would not last 5 min 30 sec longer trust me its not the case
He used 30ml in each one. The carbon cloth etc. Reduces the amount burning from the middle which saves fuel. I was concerned that it would impact the keys since the heat is needed to vaporize the fuel for the heat to work. It did take a bit longer to prime but seemed to be efficient still. I agree a boil test would be good to see how it compares.
这个燃烧测试有失偏颇，得看烧水的效率
❓
Those had better not be your mama’s good scissors. Just sayin’!
Given that the laws of thermodynamics state that energy cannot be created or destroyed, what you have done here is prolonged the time it takes to to burn a given amount of fuel by decreasing the burn rate and btu output of the stove, thus crating a less efficient stove that will take longer to cook or boil anything you put on it.
If there was a way to make their superlative burner more efficient, Trangia would have done it years ago. Stick with what you know and love folks.
Modified is less hot than unmodified... orange flame, blue flame, white flame? Which one is hotter? The white the flame rhe hotter.... orange means more toxic and less temperature of the plasma o flame it also means burning the fuel faster.
