The Yellow Heat Burner.
PRINCIPLE OF OPERATION
a.
The Yellow Heat Burner operates on the Babington Principal where moderate air pressure
(10 to 40 psi) eminating from a hollow sperical surface has shearing action on a laminar
film of fluid flowing down the surface. The film of oil flows across a small hole or thin
slot, causing the exiting air stream to break up the oil film into a fine mist. The adjacent
electrodes then ignite the mist to cleanly combust. Some of the oil is not combusted, but
runs off the bottom of the Babington ball and is returned to the oil reservoir. Because the
oil is not forced through a constricted opening or orifice, there is no chance that the burner
can be clogged by unfiltered oil.
b.
The Yellow Heat Burner operates on liquid vegetable oil or other liquid fuels. Saturated
hydrogenated oils, including congealed oils may be combusted if they are liquified
sufficiently. The high efficiency Fuel Conditioner elevates the fuel temperature just before
combustion to reduce viscosity. This is a low-wattage device, consumes less than 1 KWH
per day in normal operation.
c.
Experience will quickly show which oils are better than others. Wet or emulsifed oils do
not burn as easily as fully separated oils that are drier. The Yellow Heat Burner operates
on oil, not water or sludge. Purchased yellow grease or waste vegetable oil should contain
less than 2% M.I.U. (Moisture, Inert materials and Unsponifiable substances).
d.
When adding fuel to the Yellow Heat Burner storage tank, observe the entering liquid
stream. At least some light should be able to pass through the stream when poured into
the Input Screen. If the entering stream is opaque, that is not oil, that’s sludge! A separate
process is usually required to effectively separate oil from sludge.
e.
The Yellow Heat Burner is available with two burner head options. These are
interchangeable burner heads allow a wider range of heat outputs to match the heating
applicance chosen. For example, a domestic hot water heater has a smaller firebox than a
whole house furnace. For the smaller firebox the burner is to be equipped with Burner #1.
For larger firebox, use Burner #2.
