Synthetic polymers
Remarks:
If injection viscosity of max. 24 cSt cannot be achieved with an unheated fuel, fuel oil system has to be equipped
with a heater.
1)
Ignition properties have to be equal to or better than requirements for fossil fuels, i.e. CN min. 35 for MDF and
CCAI max. 870 for HFO.
2)
Cloud point and cold filter plugging point have to be at least 10°C below the fuel injection temperature.
3)
Biofuels originating from food industry can contain synthetic polymers, like e.g. styrene, propene and ethylene
used in packing material. Such compounds can cause filter clogging and shall thus not be present in biofuels.
