Waste Motor Oil / Lighting Oil
« on: February 06, 2012, 08:58:18 am »
Hello,

I have modified a Becket AFG to run on waste oil.

Here is what I have done:

* Changed nozzle from the rated .85 to .55 same pattern & angel (70* Solid)
* Added PID, thermocouple, and cartridge heater clampled around J-tube inside barrel
* Filter oil through a 10 Micron hydraulic oil filter and throught a RF-1 filter
* Turned pump pressure up to 135psi
* Operate PID at about 350*F

What I have found:
   The unit lights and runs fine but I plug nozzles like crazy. I understand that  I should run the temperature around 170*F. This is fine, however I cannot get the unit to light at 170*F.

Is there a differnt adjustment other than factory for the electrodes or another trick?

Any help is appreciated.
