reply to your request with respect to the certification of the efficacy
of your additive service which we have been using since September of
1.997, we would like to show the following facts which we authorise for
- Our cogeneration plant is equipped with 2 DEUTZ MWM engines, type TBD
645 L9, with a power of 3,5 Mwe
each one. The engines were put in operation in April - 96 and are
using fuel oil nº 1 BIA as fuel.
- After some
adjustments in the operation of the installation carried out between the
implementation and the June ’97 inspection, we decided to prevent the
corrosion problem of the exhaust valves of the present engines from the
beginning of operation.
To this end, knowing the results obtained in the cogeneration
plant of MSM, belonging to our Business Group SAMCA, we decided to
contract the services of rb bertomeu S.L.
- Since we began the additive treatment in September - 97 of fuel - oil
Nº BIA “rb bertomeu” products beco Mg and later “rb bertomeu”
beco F1/ASF, practically all the corrosion problems previously cited
have disappeared, which has produced a great saving in maintenance and
we note the disappearance of the serious residual encrustation that was
produced in the exhaust valves as well as in elements of the exhaust gas
- Finally, we appreciate the technical collaboration that we have
received, through assistance in engine inspections, analysis of
combustion gases, compilation of follow-up information, etc., all
immensely useful for our plant management.
