Tom,
I have a tank less hot water heater that I can easily adjust the temp from
100 to 176 F, I put the oil in a pete bottle, filled the sink with 176f
water and set the bottle in it. I checked it after a few minutes and it was
in the process of turning translucent. The next morning it had stratified
as I indicated. I neglected to tell you that the white layer seem almost
solid. When I tipped the bottle it wanted to stay in place. Later today I
will pour it into a pan and see if I get any snap-crackle-pop, indicating
that Andres is correct.
I am using BD for a backup generator for my solar system. It can get very
cold (sub zero) and my generator is in a shed attached to the house. Due to
ventilation requirements it gets almost as cold in the shed.
Now that I am 100% clean on the electrical side, I would love to reduce my
propane use. I use propane for heat, and hot water. What kind of furnace
are you using to burn BD? I am looking for some kind of free standing stove
to heat our basement (which in turn will heat the house, I have in-floor
propane heated hydronics in the basement floor, which I designed to then
heat the whole house). We were planning to put in a wood stove, but after I
started the BD project I am leaning hard toward an oil stove.
Love to hear how bacon and egg exhaust goes.
And lastly....
YOU BUSTED ME!
(I don't titrate)
I spent more than a week trying titration, and ended in total frustration.
I could never get it to work. So using poor man titration, and lots of
trial and error with the blender, I use the two stage process with beautiful
results (passes the quality tests with flying colors). My formula is 10g
KOH/1 liter Methanol. 25% Methoxide. 75% first stage - 25% second. 3
vigorous washes and its done!
:-)

Luke,
"So chicken fat it is." Maybe.
Did you use bottom heat? as in a pot on the stove?
If so, did it crackle a bit? Any water on the bottom?
If you used a submersible heater, did bubbles form around the heating
element?
The white stuff , "about 5%", might be water.
I use 100% BD in my car until night temps get down around freezing
(32F
/~2C). I then go to a 70% BD : 30% winterized petro diesel blend. 32F is a
good deal below the cloud point of my BD. (You can check your BD by putting
it in the fridge, check occassionally, read temp when it starts to cloud.)
I
drive an '82 Mercedes 300SD. I think it would pump jello.
Last year I "winterized" my BD as described at JTF.
This year I have separated WVO with the lowest cloud point from WVO that
clouds at high temps. When the temps go down, the stuff that clouds easily
becomes heating fuel for my house ... tank in basement, the other stuff
becomes BD for my car ... outside in the cold.
I actually like BD made from the WVO w. chicken fat. The car exhaust
smells more like a barbeque than like french fries. My next 20 gal (76L)
batch will have about 5 gal of bacon grease .... solid, had to melt it.
It'll go in the car. I sometimes go fishing w a friend early in the
morning.
He has requested bacon and egg exhaust. Maybe this next batch will fit the
bill.
Good luck w the WVO
By the way, what do you get for a titration on it?
Tom
