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

A conversion to a Wayne burner using a Craig Kepner (ckburner) kit. Craig thought out this block very well,it fits in a 9" tube and has holders for the electrodes
The first mod is to extend the air tube (blast tube) to hold the preheater and a hole in it for the fuel line.
I welded some 4" exhault pipe to the short tube I had but you can buy a 9" tube from beckett.
