Meths/Alcohol Vaporizer/Burner refurbishment
By: PO9R4S4CHE Date: July 10, 2021, 8:31 pm
---------------------------------------------------------
This burner showed with engine [Bing 130/114] in rough shape.
The front vent hole was clogged. A vent hole was drilled in the
back opposite corner. Both pilot stems were blocked. It came
with large wicks.
It worked albiet it was a poor burner and would occasionally
ignite and I worried about smy engines sides melting. and
safety. of course.
Unblocking the stems after some time and not wanting to use
crazy chemicals and knowing that I would need to figure out the
fillet cap situation [missing and center screw part too] i
decided i would use a torch and melt the two pilot tubes out to
unclog them.
They each had remnants of 2 diff types of fuse/wick each in bad
shape. each torched and burnt and packed down so tight from
years of age.. I was able to unclog front vent with paperclip.
in the first photo i had already shodily and casually replaced
them knowing more precise work was needed.
I looked more carefully at the plug that was in place and
realized it had filler cap threading. [required glasses
👓] and cleaned up the previous repair job. I melted
off old solder and sanded and re soldered. closed up the back
hole as well.
These burners need to be maintained and kept clean. they also
need to be air tight and sealed so that the ventilation works.
Without the proper venting and vaccum they do not burn
effecient.
Heres how it turned out let me know I can post more pictures or
larger ones.
As always suggestions and feed back or advice allways
appreciated.
Thanks Guys

My observations while doing this.
I wish my skills were better!
I find the burners need cotton wick. But have been
experimenting with natural fiber and I have been weaving my own
wicks
Denatured Alcohol Burns and vaporizes best. Seems hottest by
far. 91% isopropyl alcohol seems to work not as hot but its
legal and easy to find in California. Denatured is not
[methylated spirits] i have to still try everclear liquor[120
proof 60abv] alcohol
Never use oil! these are vaporizors
These need that airlock, and any tiny hole is bad. The alcohol
finds any way out it can, having any microholes itncan come out
and ignite.
for those wondering how these work if i can explain best I can.
Fill burner with denatured alcohol. The wicks suck up the
alcohol and will light like a lamp. in this case you can only
light the pilot light. the large wick and mushroom top will not
light until it warms up and is hot enough to vaporizer the
alcohol in the large wick. this spreads out and you get flame.
the wicking action creates a suction and flow requiring proper
venting. the more this is tuned and dialed in the better the
burn. I will post a video of a Burner this week for those
interested. as a Pyromaniac [3rd? hobby] these are in my top 10
of flame producing items.
Enjoy
Jason

Hi Jason,
A good work. These "mushroom burners" have a great advantage
over the wick burners. They produce greater heat under the
boiler due to the wider burning area. Thus, the steam generation
happens faster and more intense. Another advantage is that the
gasification of the methyl alcohol in the mushroom head and
subsequent combustion produces less soot, which then settles
under the boiler.
I have never experimented with making my own wicks. There are
quite inexpensive cotton wicks that are infused with fiberglass.
These wicks hardly carbonize at the tip and again reduce soot
formation. This is true for the simple wick burners.
Burning the wicks in the mushroom head burners must not happen
anyway, since the wicks only serve to transport the alcohol into
the heads, where the alcohol mixes with air (gasification).

Dampfopa, took some photos.
first wicks on left were the ones stuck in burner. then the wad
of rope twine came with burner [my inspiration] i noticed the
white cotton cord burns horrible.
the brown cord is a hemp or sort of natural teine. i rememeberd
back in the scouts this was soaked in kerosene so as to prevemt
bugs and also aging. its highly wickable.
the braided on i made with the string kept doubling back. the
burnt tip is cause it was too long and came into contact with
burner head. it workes very well. the thick white cotton wick
was the original coming with burner.[attachimg=1]

not the original filler cap. i traded it for another machine.
this cap is aftermarket! but came with engine. the burner i
had bought complete but i like this new "filler cap" looks
kinda ornate. but more important it holds burner in from sliding
out against bottom lip of the door. which in my opinion is
safer
