FUEL REQUIREMENTS
a.
Yellow Heat Burner vegetable oil fuel should meet the minimum standards of yellow
grease with less than 1% particulate matter and 1% water by weight. The specification for
purchased yellow grease to operate in the Yellow Heat burner is a maximum of 2% MIU
(Moisture, Inert materials and Unsaponifiable materials).
b.
Yellow grease may be supplied by Rendering Companies or regional yellow grease
Brokers. Check on-line to find the name of your nearest possible supplier. Alternatively,
we provide some guidance at the end of this document and in our video training program
at YellowHeat.com if you wish to collect your own yellow grease from the producers.
Many thousands of restaurants and commercial or institutional kitchens produce this
yellow grease as a waste stream.
c.
Our built-in fuel handling system will process yellow grease for use as a combustion fuel.
This consists of several components, including a stainless steel 40-mesh screen bucket in a
funnel, a water and sludge draining system, and a floating draw-off. With our unique
processing system, one can add large volumes of yellow grease directly to the
Oil
Handling System
and the fuel processing is nearly automatic. If the fuel is not processed
through the
Oil Handling System
, make sure it meets the requirements of yellow grease.
d.
A 60-mesh strainer is included between the Floating Draw-Off and the Fuel Pump. This is
a large capacity strainer but will need to be cleaned at least yearly, or more often if
especially dirty oils are used. The straining element is cleanable and reusable.
e.
The fuel pump has a screen with 160 mesh surrounding the intake. This screen will need
to be cleaned at least annually. A new strainer screen and pump gasket are recommended
at annual maintenance time.
f.
If waste petroleum oils are used, we recommend only motor oil, gear oil of SAE 80 weight
or less, hydraulic oils, ATF, #1 or #2 furnace oil, or diesel fuel. Pour all fuels through the
40-mesh screen. Any resulting solid waste is potentially hazardous or toxic and must be
legally disposed.
g.
A consistent fuel or blend of fuels will provide consistent burner operation. While the
Yellow Heat Burner can operate on a blend of oils, varying the consistency or blend of the
fuel may require periodic attendance and tuning to optimize safe and efficient
performance. Temperature, viscosity, moisture and grade of the oils affect flame size.
Vegetable oils yield approximately 5% less heat per gallon compared to petroleum oils.
Wet oils yield less heat than dry oils.
h.
Some wet or thick yellow grease will burn at a substantially higher heat with the addition
on a small amount (5 to 10%) of petroleum, such as home heating oil, diesel fuel or
kerosene.
