Stephen, I've been "working" on this idea for some time. I acquired a spare Becket burner that I will continue experimenting with. I have a 115,000 BTU oil-fired burner ( no water jacket involved) for the household heat. The motor (not on the burner) for moving the forced hot air around the house is 1725rpm. The nozzle is 1.25 gal /hr.
Regarding your project, The timer you need to delay the wvo/ho mixture is already built into your system at the variable-heat differential switch which starts the forced hot air fan. Mine is set at about two minutes, but can be lengthened. I still need to set up an electric zone-valve for the switch-over which also will require a separate tank. I think an old converted 75 gallon water tank just might do the trick, but of course this would not pass city code inspection. Better off with a standard oil tank, but depending on the situation of where it's located, it might need Seems like a separate pump would also be needed. What would be ideal is if the other side of the shaft on the main electric blower/ fuel pump motor of the primary burner could turn an auxillary second pump for that extra tank. Then the only connection between the two two would be that switchable valve. Another aspect I've been looking at is the amount of heat that gets lost going up the chimney, but that's another project. My questions for are: What is the BTU output of your furnace? What nozzle size is are you using? You might be able to increase your wvo/ho ration with a larger nozzle? What is the source of your WVO and are you prefiltering before adding to the #2 heating oil? I took a look at the Babington burner which is basically an open uncontrolled flame and decided it's not the way I want to go. I feel to much can go wrong with it. With the forced hot air oil burner, everything is basically already there. I'm eager to know how your project is going. Let me know.
