Dear
Sir,
Having
recently complete 3 operational years of our Cogeneration plant,
equipped with 2 DEUTZ MWM diesel engines, model 8V 16M-640, producing
6.35 Mwe each, which operate with fuel oil Nº1 and using the “rb
bertomeu” additive beco F1/ASF from the beginning of operations in
1998, we reaffirm the valuations reflected in our letter of 1st
February 1999 (having then completed the first year of operation) and we
continue with the opinion that the continued use of the cited additive beco
F1/ASF provides us with certain improvement in the aspects that we
commented on:
-
Absence of combustion problems.
-
Absence of corrosion in exhaust valves.
-
Minimal encrustation in the exhaust gas circuit.
-
Large decrease in the generation of fuel oil sludge.
Furthermore,
upon reaching 3 years in operation, with more than 16,500 working hours
in each of the 2 engines, we have also been able to verify the
absence of corrosion in turbofans and inlet valves, which we know
have been detected in other similar plants with less working hours.
We
authorise the use of this letter, for reference purposes.
