Stack Emissions
INOV8’s management strongly believes
in environmental responsibility and continually encourages the same
from its customers. With the country becoming more environmentally
conscience, there is a strong concern for stack emissions from any
type of heating device. There is no doubt that the INOV8 burner
is the safest, most efficient and cleanest burning waste oil system
on the market, and is indicated below.
- The INOV8 furnace was tested and listed to the Underwriter Laboratory
296A standard for waste oil burning equipment. Along with safety
and performance tests, this procedure measured the stack emissions
with "smoke spot tests" on each type of oil the INOV8
product can burn. A copy of the results is attached. Please notice
that for each of the nine fuel types, the results were one-half
of the maximum allowable smoke spot test of a No. 4. The No. 2
smoke spot result with the INOV8 burner is the same as obtained
from residential type oil heating equipment. We conclude then,
that when the INOV8 burner is running as designed; it will perform
with the same cleanliness as a standard residential furnace.
- INOV8 routinely tests the efficiency of our burners with a four-gas
analyzer that detects levels of hydrocarbon molecules, oxygen,
carbon monoxide and carbon dioxide. It also measures excess air.
These measurements combined with the temperature of the chimney
allow us to determine efficiency. In a laboratory setting we are
able to achieve nearly stoichiometric combustion (complete combustion)
that is indicated when the excess air ratio is nearly zero. In
practice we operate between 3% and 8% excess air to insure normal
operations and account for on-site adjustments.
- A Federal EPA report authored in 1984 by Robert E. Hall is cited
as the guideline for all subsequent reports relating to small
on-site waste oil burning equipment. The EPA documented in this
report a combustion test burning various waste oils with hydrocarbon
molecules tainted with other chemicals. This test was to determine
the destruction removal efficiency or DRE required destroying
any available molecules. The EPA report concluded that when combustion
temperatures range between 2000o and 2500oF, then DRE approaches
100%. Because the temperature of the combustion flame on the INOV8
burner is within that range, we can conclude that nearly all of
the available molecules are effectively destroyed and converted
to usable thermal energy.
- INOV8 runs four test units at our plant on a continual basis.
We test each burner prior to shipping, perform variance tests
on extreme conditions, and routinely test a wide variety of fuels
to accommodate unusual customer requests. Considering the continual
operation and unusual conditions, there has never been a black
soot build-up on our chimneys as is readily seen on competitive
units. Their blackened chimneys are indications of incomplete
combustion and are accumulations of unburned carbon molecules,
and possibly other things. A chimney on an INOV8 furnace will
remain clean because of the nearly complete destruction efficiency
in which all carbon molecules are consumed. If a burner has been
improperly adjusted with too rich a fuel mixture, then there is
a chance of carbon molecules escaping. The INOV8 serviceman should
readily detect improper settings by sporadic burning and chugging
sounds.
- Another important reason the INOV8 chimney remains clean is
attributed to the design of the heat exchanger. This can be most
appreciated when compared to a competitive unit that is a single-pass
heat exchanger. The burner fires into a combustion chamber. The
chimney opening is at the opposite end of the combustion chamber.
Through the process of combustion, air pressure creates high levels
of turbulence within the combustion chamber carrying high amounts
of the ash residue or unburned carbon molecules into the flue
products. These are simply carried up the chimney and outside
onto the chimney, roof and surrounding area.
By comparison, the INOV8 unit has a three-pass heat exchanger that
entraps much of the products of combustion when the flue gases are
forced to change direction three times. For that reason, the INOV8
furnace will require cleaning more often than the single-pass heat
exchanger of our competitors', but will not pollute the air or surroundings.
