Haynes, I get no sparks with high pressure AOF, but did before I added that. I have high pressure Air over fire (AOF) and high pressure air under fire (AUF). My blower is turned on after about 1 minute of lighting the fire and does not get shut off until after the coals at the end of the boil are nearly gone. With AOF the sparks are consumed under the pans, well before they exit the stack, Ash does blow out the stack but with no visible sparks, even on the darkest nights.
I have a forge, but I use no blast gate to adjust, however mine is a #400 hand crank blower, not an electric.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
