I was wondering if anyone had any drip plate specs to share. How important
is the angle of the plates? If one is to mix oil drip and water drip do I
need a mixing plate in advance? Could I just drip both on the same first
plate? Couple of questions here...Thanks in advance for your input if I
don't do it later , Agin Thanks, Eric

There was a guy at NCECA this year who had a really slick design. I
can't remember his name right now, but perhaps someone else on list
can. he was supposed to be putting the information from his power
point presentation on the web for all to see. the drip plates were
built into the side of the kiln.
angle is important, since you don't want the oil running off too fast
or too slow.

Dig out Hank's last post on his oil kiln. It's the most scientific data out
there for fuel oil
Look at http://www.cd3wd.com/cd3wd_40/CD3WD/APPRTECH/G15SEE/EN/B961.HTM

real help. Be very careful of leaks. Once a puddle of oil starts burning
near a kiln its going to be difficult to put out.
I could be deluded, but I like Clary's glazes better with oil (she used
heating oil).
I am hoping to build a tar ball kiln.
Good luck, I sure claim no expertise on this.

One of the issues I have is oil, like wood, is a fuel which needs a firebox
to gassify.
I think applications in which the plates are stuck in a burner port as if
they are a gas burner results in smoke and clinkers.
For the oil burner tests I've been doing I'ved developed some guestimators
that are crudely accurate.
1. Burner plate area at 4.5S.I. for each S.F. of the kiln's interior
surface (2.75S.I. for IFB kilns)
2. Fireboxes at 57btuh/cu. in of fire box
If a 2ft cube IFB kiln is 24SF surface then plate area is 66SI add 50% for
extras =3D99SI
If (per olsen) this kiln needs 80000btuh heat input then firebor volume is
80000/57 or 1403 cu in.
