Charles,
I've been burning approx 30% biodiesel: 70% home heating oil this past
heating season. The only problems I've experienced are to be expected :
Change line filter element and nozzle due to the cleansing action of BD on
an old tank and fuel line. Learn how to do this yourself and have spare
filters/nozzles on hand.
I have a Beckett AF burner with a Suntec pump. The pump (and most
others) has a rubber shaft seal which is incompatible w. BD. It will
eventually swell and leak. I did not experience any problem with it for the
8 months I've used it w. BD30. My tank is in my basement and I did not
preheat the mix even though temps go down to about 50F down there.
This past week I have teed a small "experimental" tank
into the fuel line and am attempting to run BD100 in the furnace. I
replaced the Suntec pump w. a Webster Bio Pump (w. viton seals); very easy
to do.
So far: I've been able to run BD70 by adjusting the pressure screw on
the pump (increase) and adjusting the air band on the burner (lowered).
Knowing little about burners, furnaces, and pumps, and lacking pressure
gauges, I limited myself to 1/2 turn on the pressure adjustment. A service
tech is coming today from the local oil co. to see if he can get it going on
BD100.
Congratulations on your successful batch and best wishes,
Tom

Just also wanted to share my excitement at making my first 1l batch from
WVO- processed well and the third wash is crystal clear!
