Guidance for the use of bio fuel blends up to 10% where gas oil use is permitted by the appliance
Manufacturer
Background
With increasing focus on renewable and sustainable energy re-
quirements, Bio fuel usage is set to increase. Riello is committed
to promoting energy conservation and the use of renewable en-
ergy from sustainable resources including liquid bio fuels, howev-
er 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 Bio fuel 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 from the specification
of the liquid Bio fuel, the storage of the fuel, its oil supply line and
ancillary equipment, and very importantly the oil filtration and the
burner itself. The specification for FAME (Fatty Acids Methyl Es-
ter) liquid Bio fuel is critical to reliable equipment operation.
It is a minimum requirement that the fuel blend (up to 10% Bio) is
obtained with gasoil 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 require-
ments related to operational environment conditions within the
relevant EN standards.
When choosing your Riello oil products where you know Bio fuels
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 Bio fuel 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 bio fuel blend and the suitability of the appli-
ances and installation applicable.
Irrespective of any warranty given by Riello in relation to normal
use and manufacturing defects, when fuels not meeting the rele-
vant standards are used, or where fuel storage issues have not
been addressed correctly, or the equipment used is not compat-
ible, if failures occur which are directly or indirectly attributed to
such issues and/or to the non-observance of this guidance, then
no warranty or liability is implied or accepted by Riello.
