reply to your request we are pleased to certify that since April 1999 (almost
2 years) we have been using "rb bertomeu" additives for
fuel oil beco Fl/ASF in our Co-generation Plant at San Saturnino,
with total satisfaction inasmuch as its use has eliminated the serious
corrosion problem that we had had from the beginning of operation. Also,
we can express our satisfaction with the Technical Service, regarding
the analysis of exhaust gases and inspection of valves of the engines,
which has been provided for us.
plant is equipped with 4 Deutz MWM Diesel engines, type BV 16M-640, and
since we began the additive treatment with “rb bertomeu” beco FI/ASF,
we have noted a practical elimination of corrosion in exhaust valves,
which was previously frequent and was caused us breakdowns due to blown
valves and high maintenance expenses.
This has allowed us to raise the service factor of the
plant and to achieve a greater operation continuity, being able to
increase the TBO used in valve inspection from 2,000 to 3,000 hours to
3,000 to 4,000 (and in some instances 5,000) hours.
the use of the additive beco F1/ASF in the fuel, we also have
detected the processes following improvement with respect to prior data
in the following aspects:
Reduction of fuel oil sludge with respect to the volume that was
previously generated in the storage tank as well as in the fuel purifier
Absence of corrosion in the inlet valves of the engines.
Absence of corrosion in the turbos.
A lower need to clean the fuel
oil circuits and purifiers.
Greatly decreased residues in the exhaust valves, turbos, gas
collectors, etc., which in reduces cleaning necessities, and raises the
service factor of the Plant.
Elimination of black smoke due to incorrect combustion and a
reduction of CO, which means a reduction of pollution and fuel
Decrease of the fuel consumption per kWhe produced (hardly
appreciable but improved considerably by the loss in sludge).
