Household oil burners were a simple design. They use electrodes to
ignite the oil. Air is pumped at a steady 100 pound pressure. Nozzles
are designed to burner and certian angles and at so many gallons per
hours. i.e. .75 gal/hr or 1.5 gal/hr. This determines the BTU output of
the burner...how many gallons per hour it burns. They use to be found at
the dump when the pumps went out or the electrodes no longer worked.
Scrounging dumps one could find enough parts to build some working ones.
With the electrodes igniting the fuel oil, they burned clean.
When using then without electrodes and into a big cold kiln, trouble
arises with clinkers (carbon from insufficient combustion). This also
makes for dirty exhaust.
I have a design in the old Studio Potter book for adapting fuel oil
burners by putting three nozzles into the combustion tube rather than
one as on household burners. Then having three valves to use one, two or
three nozzles of various sizes to control the BTU output.
Just a note,
