At this point there are no U.S.A. makers of bio-D burners.
OTOH, WVO will not cause seal swelling and a mix could be run now. Reports of 20% WVO to 80% HHO mix with no ignition or gelling problems.

Alge growth is a water issue. I treat my WVO stock Barrels
with bioguard just in case. Plus I run 1/2 oz in each tank.
I also run some isopropyl once in awhile.

Increased viscosity from cold weather is the reason for the RUG. I've heard it mentioned that old MB manuals allow up to a 30% mix of RUG into dino diesel. Plus the PS/DK has anti gel properties, whether they work on WVO
is another question? It had been reported that an 80%WVO / 20% RUG is good down to 17F.

I have had no fouling problems...yet. I ran a few tanks of bioguard in shock quantities first. Along with several brands of fuel/injector treatment. I find West Marine has a good assortment of Diesel products.

My furnace is the typical Burnham variety, model #pv75wt-tbwf, then it says v-7 series. Guess I'm screwed with that idea. Man I hate using wood but looks like we'll have to keep the wood boiler burning. I will try the WVO so long as you're sure that won't mess anything up. I will not have any gelling problems as my two 275 gal. tanks are in the basement. I'm assuming I have to filter the WVO to 5 microns as well?

"I also run some isopropyl once in a while". How much? And did you mean in the cars fuel tank?

Being a boater I am famaliar with West Marine.

Thanks again....

Cheers,

Bill

I'll do some freezer tests on the WVO/RUG blends along with the PS additives and share my data.

Here is some other data,I look foword to your test results, Tom.

TEST RESULTS: SEE PAGE 3 FOR PREVIOUS TESTS RUN AT 20degC ( 68 F )

Here are results of the colder run viscosity tests, all run at 4?c ( 39deg f ).
Tests run under the same conditions as before i.e. 20ml pipette etc. see pg 3 this subject.
Using petro Diesel as the standard again ?
DIESEL = 16
B100 = 16
B100 / DIESEL = 16
45%WVO / 45%B100 / 10% RUG = 20
50% WVO / 50% DIESEL = 27
50% WVO / 50% B100 = 27
80% WVO / 20% RUG = 32

Diesel and B100 ran the same as the 20 degree C. tests, but as you can see any blend with WVO in it, thickened up.
Viscosity. Diesel 16 seconds = 1

DIESEL = 1
B100 = 1
B100 / DIESEL = 1
45%WVO / 45%B100 / 10% RUG = 1.25
50% WVO / 50% DIESEL = 1.68
50% WVO / 50% B100 = 1.68
80% WVO / 20% RUG = 2

It can be seen that a drop in temperature of 16 degrees C (from 20 to 4 deg.C ) has moved the viscosity of the 80wvo / 20rug blend from 1.62 times that of diesel, to twice the viscosity of diesel.

The biodiesel at 4 deg.C had started to wax considerably and had to be filtered again to remove solids.

All blends with Diesel or RUG in it had not waxed and remained clear.

I would probably think that as a result of this anyone running a blend with a high % of WVO in cold climates should think about heating the tank. I would think a viscosity of twice that of diesel oil would start to place a load on a rotary IP that it was not designed to take. An inline or jerk pump would probably not be an issue. ( If in doubt consult an IP mechanic)

Last winter I mixed a small bottle of SVO soybean fresh vo w/ 10% unleaded gas. It mixed well altho it got cloudy. It didn't separate for 3 months, even through several freeze - thaw cycles when temperatures dropped below 18*F.
Thanks in advance,

Jim Burke

Oh, BTW, I talked to Perry Pillard at Greasel, yesterday, I think. He said that they had a sample of 80/20 veggie/gasoline mix that has been in the REFRIGERATOR since DECEMBER, and that it has still not separated, nor gelled!

I'll keep y'all posted.

Good Vegging and God Bless!!

Search through this group Bill, http://groups.yahoo.com/group/altfuelfurnace/
There was a discussion of blending WVO & HHO. My memory tells me 80/20, but double check me. Being your tank is in the basement, gelling won't be a problem. Start-up may be at higher concentrations. Also have to think about coking up the nozzle. Lots of good guys and info at that group.

Yes filtering is imperative for any use.

Yes in the car, I just follow the instructions on the iso bottle. One 6 or 8oz (?) bottle to 10gallons of fuel.
PSDK and Meaner Kleaner deal with water also.
I'm going to start fry pan testing my oil batches for water.
But I think you can't be too careful
