Paul,
Thanks for the response.
You have me thinking.
The BD that I added to my fuel oil clouded at 52 -
54F. My basement can drop down into the 40's. I had assumed that by mixing it
with heating oil the cloud point would be decreased. Maybe that was an incorrect
assumption.
Is this what I can expect
from BD that has clouded at low temps - a jelly-like buildup on the nozzle of my
furnace.
Can I solve the problem by heating the fuel
line?
Thinking something like
this might happen, I learned how to change the nozzle before my father-in-law
headed for warmer climes.
Thanks
again,
Tom

Burner
Tom,
Do you have a clear sight tube after that copper line
before the burner?
You could see if the fuel is cloudy before it gets
to the burner.
Or you could keep a mason jar of your mixed fuel
near the fuel line where it would maintain the same temperature and you could
see if it stays clear.

Jan,
Thanks for your prompt
response.
My first thought upon
hearing of a leak from the burner was that there was a problem with a rubber
component such as a seal. (I had been assured that, since the burner was
installed in 1992, the seals were all synthetic and would not leak). If that
were the case it should still be leaking, no? More than two weeks after the
nozzle was replaced and the blast tube was adjusted there is no sign of a
leak.
The explanation for
the puddle of oil (from the service man) was that the clogged nozzle was not
spraying all of the oil into the ignition spark. The furnace was not burning
all of the oil being sprayed though the nozzle. Unburned oil was dripping
down the blast tube.
I also considered that
the jelled BD should be trapped in the filter (and possibly clog it). The
filter is located at the tank. There is no second filter in the frunace. My
concern is that the fuel travels 12ft through narrow copper tubing along the
floor at an exterior wall in a basement that currently is 45F. Could it be
flowing through the filter, only to cool further inside the fuel line on its
way to the burner?
I didn't see the jelly
on the nozzle so I can't comment on its appearance.
There was an add in
the local paper for Biodiesel Heating Fuel. The add stated that it could be
used in any burner that used heating oil. I appreciate your help, as one of
my goals is to provide low cost .. as in free ... heating oil to
people in need in my community. I have to get it to work in my own furnace
first.
Thanks again,
Tom
