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:

Note : TBO = Time Between Overhauls

 

TIME-PERIOD OF VERIFICACION

        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.

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.
