decrease in fuel economy, an increase in emissions and a
decrease in power.
A two-step approach for maximum
protection
Because unscheduled downtime can be incredibly costly on a
mining operation, choosing the best available onboard fuel
filters is to protect injectors. And providing effective
projection for injectors can sometimes create additional
challenges. Contaminated fuel can cause rapid plugging of
onboard filters, which means unscheduled trips to the
maintenance garage for haul trucks, dozers, loaders and
other heavy-duty mining equipment.
Traditionally, only top performing on-engine filters would
be used to remove the contamination in the fuel to meet
injection system fuel cleanliness specifications. But the
requirements for HPCR fuel are so clean that a four-step
filtration approach, with a new focus on bulk storage tanks,
is often needed to maintain service intervals and achieve
consistent cleanliness:
n
n
Filter fuel from the supplier, as it goes into the bulk
storage tank.
n
n
Protect the fuel while it is stored.
n
n
Filter it again as it is dispensed before use in the
equipment.
n
n
Filter it again as a last layer of protection with efficient
on engine filters.
By current standards, bulk filters should remove
contamination in fuel down to a cleanliness level of
ISO 14/13/11, whether the contaminant present is hard or
soft. It should be noted that all on-engine fuel
filters are designed with the goal of removing hard
inorganic particles typically found in fuel. They
will also filter soft organic materials; however,
filter life can be drastically reduced when excessive
amounts of organic material are present.
Besides meeting HPCR fuel cleanliness
requirements, the use of bulk filtration also
provides necessary protection against any highly
contaminated fuel that may be delivered (ongoing
or as a one-time occurrence). By filtering before
use in the equipment, the bulk filtration system
will stop excess organic and inorganic particulate
from being delivered into equipment’s tanks,
ensuring the onboard filters can meet the expected
service intervals.
“If excessive fuel contamination does exist, it
may plug up the bulk filters, but save the
on‑engine filters,” Doyle said. “This helps
eliminate costly unscheduled downtime and
makes operation and maintenance much more
predictable.”
Conclusion
Use of high‑efficiency filtration at the inlet of a fuel
storage tank infrastructure will help protect
against taking delivery of dirty fuel. Additionally,
adding an effective breather filter on the tank will
help combat the entrance of ambient dirt and
moisture.
Ensuring fuel is clean before storage is a must,
but one should recognise that contamination
happens within storage tanks as well. Therefore,
filtering fuel as it is being dispensed into the
equipment will help safeguard machinery. This
will be the best chance to protect against any
contamination that may have been introduced in
storage – tank scaling, contamination from piping,
or general fuel/additive stability problems.
In conclusion, today’s engines –
Tier 4 and otherwise – are more sophisticated than
ever and require cleaner fuel than ever before.
