 Ummmmm No don't keep the heat on because it will cook inside the nozzle and polymerize , then its clean or replace nozzle time.

 Hey Steve, sorry for the oh so late reply Iv not been on here for a few weeks.  There are a few pics at the top of this thread. Its the brass piece screwed into the block. You can google delavan siphon nozzle or hago siphon nozzle to see the other end. It has a stem with o ring on it.

Burned a half quart of WVO in it today and it has the dreaded wet chamber. Will make a burn tube soon.

 Getting it together

 I build this way for easy clean out.

 The answer is simple, Can not be done  If you give a sample of oil then the results can be made known by lab or whatever.  The term waste oil is due to the fact it is contaminated with unknown items. Manufacturer can not say that the burners burns to within a certain specification unless the oil specification is defined.

Well I am a bit confused by your drawing and the pix. The pix look to be a square (rectangle) firebox with the hut type refractory sitting there with its round hole.  The drawing shows the steel casing wrapped around the hut is this the case?
  Can you remove the hut and have a empty square steel box?
If so, extend the box line it with fire brick or plastic refractory and put a big door on it with a 4 1/4'" hole to mount the burner on.

 The big door is a pluss as clean out will need to be done every month or so.

This is why my build is all so very simple made from 10" pipe with flanges, to be easy to clean.

Cheers  D.E.

Look at how Dutch John at altfuel built his extension " Just add on to the box and a door to mount burner on,makes clean out a snap.

 I like this method.

Fuel Pre-Heaters / Re: waste oil pre heater thoughts

Consider this whan designing the block. Air and oil need to be preheated, then after the burn is done the oil needs to drain back from the nozzle or else it will polymerize from the heat inside the nozzle/block.

  In the typical siphon setup the oil is drawn up(a few inches) from the constant level device by the air exiting the nozzle (venturi effect) . When the air is stopped this same few inches pulls the oil from the nozzle as the feed line drains back into the C/L devece.

  Most well tuned setups keep a slight tilt downhill from nozzle to the C/L to assist in this drainage or the nozzle will require more frequent cleaning of the carmelized/polymerized/baked oil.

 If you plan to overfeed the nozzle (anything over 1gpm) this can still be done by using a 3 way solenoid valve and a catch can for the drain back.

Just a few thoughts

 I would stay with 500w . Yes copper conducts better but you still need a bit more power considering the high fire rate.
 The air will remove lots of heat as well as the oil getting preheated. You want to get 1.5 gpm fire rate so will you be using a metering pump or a constant level device above centerline (pressure over siphon).

Looks like it should work out ok, These waste oil conversions are often trial and error with the combustion chamber design. #1 and 2 oils have a very low flash point compared to heavy oils. There is a lot a talk at altfuel group about the dreaded wet fire box, were unburned fuel soakes the chamber walls, the fix is what they call a liner or burn tube, this holds the fire and fuel together so it completes combustion. I am having a hard time explaining it~ Anyhow the small start of a square tunnel and the round hole could be beneficial in this respect, holding the heat in the spray of oil.

 Here is a diagram I am about to do. The 10" pipe is built and a tial run had wet walls inside, I will but a tube inside the help finish off combustion.

here are a few visulizations to help. The entire burner must come back at least 3 inch plus IF the tube you have is not 8"or 9" then that also.  See my post in plan section were I extended my tube to hold the ck block, you can see the weld.

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.

A Kagi retention head.

A spring added to top of preheater block to hold center

The PID temp control to left side

Plans / Siphon Burner

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

 Looking good from what I see, please do tell us more. A picture of inside would be nice too.
