TURBO-COMPRESSORS IN DIESEL ENGINES RUNNING ON HEAVY FUEL OIL.
HOW TO INCREASE ITS OPERATIONAL LIFE AND CLEANING TBO

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 consulting our website: www.rbbertomeu.es)

Next you can find letters of reference from some of our customers who have corroborated the effectiveness of the additive "rb bertomeu" beco F1/ASF.
