Experimental Babington Ball For Burning Waste Vegetable Oil
We've teamed up with Yellow Heat to bring you a really cool device called
a Babington Ball that can be used to build an experimental waste oil heater with.
Yellow Heat went back & looked at all the expired patents for this
ingenious little device and created their version for use in building small experimental waste oil heaters.
The ball is made from mild grade steel and formed into a sphere with a 1/4" threaded hole on one side
and 3 small holes at 174°, 180° and 186° from the main inlet hole. The holes are laser
cut with exact precision at 0.010" diameter. We also have two additional configurations as well.
Two Configurations Available
How It Works
Air is passed through the large hole on the ball at about 20-30 psi. The pressurized air then exits
through the 3 tiny laser cut holes on the other side. Oil is then drizzled down over the ball near these
holes. The pressurized air atomizes the oil into a fine mist that can then be ignited by an electrode
forming a flame front.
Tips & TricksUse a low air pressure, 30 psi will do it. An air-brush compressor is low energy and quiet and sufficient.
The balls are tapped for a 1/4" inlet, and mounting them on a piece of small pipe is appropriate.
The pump is often the issue. You need a small fuel stream with a steady delivery. I use a gear pump for
ease of priming and steady delivery. A clock motor would reduce the flow enough. A standard fuel pump
from a normal burner run at about 200 rpm delivers enough fuel.
Much of the oil delivered to the ball is not burned, so a return oil stream is needed.
Enough height to have it flow back to the drum avoids the need to have a return pump.
Ignitors need to be placed in front of the fuel spray. Standard ceramic ignitors will work.
Dirty vegetable oil causes a buildup of carbon on the ignitors, so make them easily removable
and cleanable. Standard ignition systems deliver 14000 volts, more than standard wires can handle
without leaking voltage. Use high voltage wires, or standard wires inside of vinyl tubing for extra
insulation. Use a standard ignition control system for safety. I use continuous spark from a Honeywell
