reply to your request we are pleased to certify that for more than 2
years (precisely since December of 1998) we have been using "rb
bertomeu" additives for fuel oil beco Fl/ASF in our Cogeneration
Plant at Boiro, with total satisfaction with respect to the initially
expected results, technical as well as economic.
Plant is equipped with a Diesel fuel oil Deutz MWM engine, type TBD 654
L9, and from its implementation we began the use of the additive beco
F1/ASF. During this time we have verified the practical absence of blows
and corrosion in exhaust valves and turbos, which we know happens with
frequency in other similar plants that use a fuel
oil of similar or equal quality.
addition to the absence of corrosion, it has provided us with a notable
economic saving above what was anticipated, we have also noted the
following data on initially expected valuations:
· Very low volume of generated fuel
oil sludge. There has only been an average of 2 Kg. of sludge per
Tm of fuel oil consumed ,
collected in the fuel purifier , with no decanting of sludge in the
general fuel oil storage
· Lower fuel consumption per kWhe produced (194 g / kWhe), which we
think is due, in part, to an optimum combustion and to the better use of
the fuel oil contained in the (not removed) sludge, both by effect of
the additive used.
· Absence of corrosion in the inlet valves of the engines.
· A very low need to clean the fuel oil circuits and purifiers.
· Greatly decreased residues in the exhaust valves, turbos, gas
collectors, etc., which in practice reduces theoretical cleaning
necessities, raises the service factor of the Plant and provides a more
stable engine operation maintaining a more constant flow of combustion
Absence of black smoke due to incorrect combustion and a very low
level of CO, which means a reduction of pollution and fuel consumption
with normally higher values.
we can also express our satisfaction with the Technical Service that has
been provided for us, mainly for the periodic analysis of exhaust gases
of the engines, which we consider as a great help to evaluate the
operating conditions and the level of emission of contaminant gases
check by the authorities.
