E03450 BAÑERES – Alicante - Spain
15th January 2001
owners of the installation "COGENERACION BAÑERES S.L" which
is located in Bañeres de Mariola (Alicante), we certifie that fuel oil
has been used with the "rb bertomeu" additive beco F1 / ASF
in our plant for exactly 5 years.
confirm our evaluations, which were included in our letters of October -
1996 and of January - 1999, that we are fully satisfied with the
results obtained from the use of this additive, even after carrying
out tests with other fuel
oil additives on the market.
the engine of our plant, DEUTZ MWM type PV 640.12 M, with a power of 4,9
MWe, reached 50,000 operation hours during which there has been a very
low level of corrosion in the exhaust valves and a corrosion level of
practically nil in the inlet valves and in the turbo.
the process, again we emphasise the reduction of fuel oil
sludge (about 50%) and the consumption saving per kWh produced
(nearly 1%), which we obtained by using the additive "rb
bertomeu" beco F1/ASF, which added to the maintenance saving
due to lack of corrosion, justifies economically, according to our
evaluations, the treatment that we apply to the fuel oil.
in previous occasions, we authorise the use of the present letter for
