Guidance for the use of biofuel blends up to 10%

Introduction
With increasing focus on renewable and sustainable energy re-
quirements, biofuel usage is set to increase. The manufacturer is
committed to promoting energy conservation and the use of re-
newable energy from sustainable resources including liquid bio-
fuels, however there are some technical aspects that must be
considered at the planning stage of using such fuels to reduce the
potential for equipment failure or the risks of fuel leakage.
Liquid biofuel is a generic description used for oil that can come
from numerous feed stocks including recycled cooking oils.
These types of oils have to be considered and treated differently
from standard mineral or fossil fuels, as they are generally more
acidic, hydroscopic and less stable.
Due to this, a holistic approach is needed for the specification of
the liquid biofuel, the storage of the fuel, its oil supply line and an-
cillary equipment, and very importantly the oil filtration and the
burner itself. The specification for FAME (Fatty Acids Methyl Es-
ter) liquid biofuel is critical to reliable equipment operation.
It is a minimum requirement that the fuel blend (up to 10% bio) is
obtained with light oil in accordance with the relevant EN stand-
ards, regional regulations and FAME in accordance with EN
14214. It is also important that the fuel blends meet the environ-
mental operating condition requisites of the relative EN stand-
ards.
When choosing your oil products where you know biofuels will be
in use, please make sure that a bio-compatible burner and/or
components have been supplied. If an existing burner is to be
used with a liquid biofuel then a kit may be required to make it
compatible and the guidance notes enclosed concerning oil stor-
age and filtration must be adhered to. The end user is responsible
for the thorough verification of the potential risks associated with
the introduction of a biofuel blend and the suitability of the appli-
ances and installation applicable.
Irrespective of any warranty given by the manufacturer in relation
to normal use and manufacturing defects, when fuels not meeting
the relevant standards are used, or where fuel storage issues
have not been addressed correctly, or the equipment used is not
compatible, if failures occur which are directly or indirectly attrib-
uted to such issues and/or to the non-observance of this guid-
ance, then no warranty or liability is implied or accepted by the
manufacturer.
