There are a lot of us here that are using or trying to use WVO in our furnaces. I really don’t think any of us are looking to see how complicated we can make it. PLEASE do what Jesse said and have a look at what others have done. I have been working at this for a while now and have been using information provided by others here. I have looked for the simplest way and have done lots of testing of ideas. This group is right. What you see here IS the simple way as complicated as it is.
Do some reading and you will find that there are two setups being used. One is the high pressure nozzle method (used on home heating furnaces) and the other is the siphon nozzle method (used on waste oil furnaces that are normally found in some commercial establishments). Your job will be to figure out which method is what you want to use and then figure out what others have done and DUPLICATE that. It will save you many hours of frustration trying to (as Jesse said) re-invent the wheel.
