The presence of
impurities in fuel oil, such as sulphur, vanadium, sodium, etc., as well as
calcium in combustion (arising from burnt engine oil and the fuel oil
itself) and the presence of unburned substances in the exhaust gases, are
the direct causes of corrosion on the components of the turbo-compressor
(blades, carcasses, etc.) and of the accumulation of solid residues on
blades, leading to a reduction in the operational life of turbo-compressors
and causing the need for frequent cleaning in order to maintain the flow of
the air supply to combustion.
The mechanisms of
corrosion by sodium vanadates are described in our Bulletin No. 1: Corrosion in exhaust valves and turbo-compressors in diesel engines running on fuel oil is preventable. Our Study “RB-11 Corrosion on Turbo-compressors” analyses the influence of daily cleaning
on engines operating intermittently and both types of corrosion usually
formed on turbo-compressors: at both high and low temperatures.
The treatment of
fuel oil with either of the additives, “rb bertomeu” beco F1/ASF
or beco F1·Ship, eliminates corrosion at high
temperatures, minimises corrosion at low temperatures and considerably
reduces incrustation of solid residues on the blades and nozzles ring, since they produce
non-corrosive residues of combustion, which are more powdery and less
adherent throughout the exhaust gas circuit.As a result, the engine
(cogeneration plant, ships, etc.) benefits from the following improvements:
LIFE SPAN OF TURBO-COMPRESSOR: Increase in operational life of between 50% and 100%
TBO FOR SCHEDULED CLEANING: Increase in TBO of 100%
These data are
endorsed by many clients of ours (you may read some references by
consulting the reference letters at the end of the Bulletin or by
