Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

To convert a gun style system (example~beckett AFG burner) to burn waste oils first obtain a suitable burner. The key issue to conversion is preheat . The burner was designed to run on #1 or #2 oil which has a much thinner viscosity and much lower flash and combustion points than waste oils.

 This can all be overcome with a preheater. There are many ways to do this, I will show the way I like the best, to use a block with a thermocouple and cartridge heater controlled by a pid.

 Here is pic of a standard burner


Here is one converted to siphon feed

 Well here is the start on the lil gun. A conversion to a Wayne burner using a Craig Kepner (ckburner) kit.

The first mod is to extend the air tube (blast tube) to hold the preheater and a hole in it for the fuel line.


A Kagi retention head.


A spring added to top of preheater block to hold center

 Hello all, glad to find a forum of waste oil heat builders. I have a half finished siphon gun conversion that I will soon be back to work on.

 I have operated, maintained, and repaired multi-million btu liquid phase heaters (Vapower units) for over a decade so this should slide along nicely.


Parts so far.

1.  Old Wayne gun style burner.
2.  4" Exhaust pipe to extend blast tube
3.  Nozzle heater block
4.  Pid controller
5.  K thermocouple
6.  Kagie retention head
7.  Float tank from old kerosene heater
8.  Combustion chamber build from 1/4" steel plate
