In a technical and economic evaluation of the use of the fuel oil additive
“rb bertomeu” beco F1/ASF in
Diesel engines, it is necessary to collect as much data as possible to facilitate the subsequent decision-making process. We have therefore compiled the following list of
benefits and savings which are detectable with the use of this additive produced by “rb
bertomeu”, accompanied by the approximate time periods required for the verification of these benefits:

DESCRIPTION
OF SAVING |
A
1 MONTH |
- REDUCTION
IN MAINTENANCE COSTS, INCLUDING CLEANING FILTERS, PURIFICATION SYSTEMS
AND FUEL LINES. The saving and improved
running are verifiable in a period of less than 1
month, during which there is a noticeable reduction in the time
needed for routine tasks of cleaning, disassembly and re-assembly of
such components.
More information at: "Bulletin No. 3: Reducing the formation of fuel oil sludge cuts fuel consumption, reducing operating costs"
|
B
2 MONTHS |
- REDUCTION
IN FUEL OIL SLUDGE OF UP TO 80-90 % (ON AVERAGE 70%). In less than
2 months, comparative data
on the build-up of sludge in purification systems may be obtained,
provided that data is available for periods prior to the use of the “rb
bertomeu” additive, and that the fuel used is of similar
quality, mainly in terms of the heavy carbon compounds and asphaltenes
it contains.

|
C
5 MONTHS |
- SAVING ON FUEL FROM 2% TO 3%, IN DIESEL ENGINES RUNNING ON FUEL
OIL.
This saving is
verifiable within a period of
around 5 months of continuous operation of the plant, provided
reliable data are available on previous consumption. In order to
obtain results of greater accuracy, the recommended method is to apply
the calorific power of the fuel oil used, in the calculation of energy
consumption per kWh produced.

D
1 TBO
|
- REDUCTION
IN COSTS OF REPLACING EXHAUST VALVES IN DIESEL ENGINES OF 69%-88%,
DEPENDING ON COMPONENT, AND A REDUCTION IN “BLOWOUTS” OF 80% ON
AVERAGE.
This significant saving is verifiable over 1 complete TBO (time between overhauls) of
exhaust valves, when a comparison may be made between valves
consumed (suffering blowouts during the period and to be discarded)
and re-usable valves (able to be reconditioned at the end of the
period). During the period of the TBO itself there is a noticeable
reduction in the number of valves requiring replacement due to
blowouts. The shorter the time the engine has been running on fuel oil
without additive treatment, the lower the number of valves needing to
be replaced due to blowouts. Therefore the greatest reduction in
blowouts and corrosion is achieved when the valves are in operation
with fuel oil treated with the “rb bertomeu” beco F1/ASF additive from the moment they are installed in the
engine.

|
E
1TBO |
- THE
TBO (Time Between Overhauls) FOR EXHAUST VALVE MAINTENANCE IS
EXTENDED BY MINIMUM OF 50%, UP TO 100%.
Once it has been
verified that the valves remain in good condition on completion of 1 TBO a decision may be taken to prolong the TBO (sometimes it is
gradually stepped up) by a percentage of between 50% and 100% of the
normal TBO.

|
F
2
TBO |
- THE
EXHAUST VALVES AND TURBOS LIFESPAN IS EXTENDED BY A
MINIMUM OF 100%.
Verifiable
on completion of 2 normal
TBOs of both valves and turbos, when the reduction in corrosion
allows both components to operate for double their average life.
More information at: "Bulletin No. 7: Doubling the operational life of exhaust valves by using additive treatment for fuel oil. and Bulletin No. 16: Exhaust valves in large engines operated with heavy fuel oil. Doubling the tbo for general overhauls."
|
G
1 TBO |
- REDUCTION
IN COSTS OF REPLACING COMPONENTS AND IN DOWNTIME CAUSED BY CORROSION
AND BY CLEANING TURBOS IN DIESEL ENGINES.
Verifiable over 1 normal
TBO. Turbocompresors are observed to be cleaner and no affected by
corrosion at the end of the TBO, and during the TBO period it has not
been necessary to carry out cleaning tasks.
More information at: "Bulletin No. 9: Turbo-compressors in diesel engines running on heavy fuel oil. How to increase its lifespan and cleaning TBO"
|
H
1 TBO
|
- REDUCTION
IN WEAR ON THE ENGINE’S INJECTION SYSTEM, RESULTING IN AN ADDITIONAL
SAVING ON FUEL OF BETWEEN 0.9% AND 1.2 % ON AVERAGE.
This saving is detected in the longer term, by means of
comparisons of data on consumption taken from the time of the
installation of the new injection system until its replacement in
accordance with the manufacturer’s guidelines. It is generally
necessary for 1 complete TBO
of the injection system to have elapsed, in order to verify that
fuel oil consumption is not affected by the usual progressive increase
caused by this factor of wear.

I
1 TBO
|
- REDUCTION
IN DOWNTIME FOR MAINTENANCE OF 30% – 50%.
This
statistic includes the reduction in downtime thanks to fewer stoppages
for general overhauls on exhaust valves and turbos. In addition to the
reduction in short stoppages, which is detectable within 2-3 months, the potential reduction in maintenance stoppages is
measurable at the end of 1
normal TBO on valves and turbos, when taking into account the
prolonged TBOs to be implemented (between 50% and 100%).

J
1 TBO
|
- INCREASED
OVERALL UTILITY FACTOR, RESULTING FROM REDUCED STOPPAGES DUE TO
BREAKDOWNS AND SCHEDULED MAINTENANCE TASKS.
As
in the previous example, in addition to the reduction in short
stoppages, which is detectable within 2-3
months, the potential annual reduction in maintenance stoppages is
measurable at the end of 1
normal TBO on valves and turbos, when taking into account the
prolonged TBOs to be implemented (between 50% and 100%). These
reductions are reflected in the potential increase in the utility
factor and the annual production capacity.
