| Unbelievable! We do clean up pretty
well. |
After trying to adapt many different pumps
to the job, I finally settled on a wiper motor tied to a Chevy oil
pump. I had burned up five different pumps before settling on this
design. It works great and shows no sign of stopping. |
 |
 |
| First attempt at using electrical controls
to run the system. The goal is to completely automate the
system. |
First version that really worked.
Still some bugs. Note the coil around the burner for heating the
oil. The pilot light is just to the right. Also, the
solenoid on the air supply. White pipe on right drains excess flow
back to tank. |
 |
 |
| My oil collection system. Suck a good
vacuum on the tank and pull up next to the source. Stick the hose
in the tank and suck it right out. This tank holds 30 gallons. |
One thing I have never seen written up on
any web site is the need for an air separator. An air bubble in
the oil will stop the flame immediately. The Tee in the bottom
center allows the air bubbles to rise while the good oil goes
down. Valve was later removed. |
 |
 |
| Overall view of system. Still very
much an experimental prototype but functional. |
Burns very clean. Only a bit of smoke
when the furnace first fires up. After a few seconds, no smoke can
be seen. |
 |
 |
| On to the next phase. Building the
shed to house the final version of the furnace. For details on the
new shop, see DB's New Workshop. |
And yet another project! An Appleseed
reactor for brewing biodiesel. For more details, see Brewing
Biodiesel. |
