10th January 2001
letter is to certify that in our Cogeneration [power] Plant, equipped with two
Deutz PV 16M440 engines, we have been using "rb bertomeu"
additives for fuel oil since September 1996, to our full
satisfaction inasmuch as ostensible improvements have been observed with
respect to periods in which were not using the fuel oil with these
more than 32,000 and 34,000 operation hours respectively in each one of
the engines, we are pleased to confirm, replying to your request, that
we have detected operational improvements in the following aspects:
Notable decrease in the corrosion and blowing in the exhaust
valves of the engines.
Absence of corrosion in the inlet valves of the engines.
Absence of corrosion in the turbos.
Residue decrease in the exhaust valves, turbos, gas collectors,
etc., which reduces cleaning necessities and raises the service factor
of the Plant.
Sharp decrease of sludge formation in tanks and fuel oil
purifiers, which has been translated into a decrease of the fuel
consumption per kWhe produced and a saving in management of fuel oil
Removal of black smoke due to incorrect combustion, which means a
reduction of pollution and fuel consumption.
we have not quantified the savings which have been produced as a
consequence of the detected improvements, we assure that overall, the
use of "rb bertomeu" additives for fuel oil provide us
with a positive economic balance (benefit - cost).
we can also express our satisfaction with the Technical Service that has
been provided for us, referring to the periodic analysis of exhaust
gases of the engines, as well as to their inspection, whose technical
and photographic reports have constituted an element of great help for
the management of the Plant in its first operational years.
