Dear Sirs,
In replay your request we are pleased to certify that we have been
using your heavy fuel oil additive
beco F1/ASF in our Co-generation [power] plant "San Cibrao" ,
located in the Industrial Area of San Cibran de Viñas (Orense), with
total satisfaction regardinf the expected benefits , economics and
thecnics.
Our plant is equiped with an engine CATERPILLAR 3616 type , running
on heavy fuel oil, with a power output of 3,440 kWe , and, during the
first years of service, we have been carried out the maintenance
operations recommended by the engine maker. The fue consumption has been
kept in the high part of the indicated normal range.
Since we start the use of the mentioned additive, just before total
dismounting of engine and turbos when where observed some solid
encrustation in turbos, some damaged injectors and pumps due to the
effect of fuel and some exhaust valves blowed out by the effect of
corrosion, we have been noted that :
We have improved the fuel consumption , due to reduction of fuel
sludge and better fuel combustion.
Improvement in the exhaust gas temperature , due to the previous
effect of optimal combustion.
Absence of black smoke due to bad combustion and low level of CO in
exhaust gases , which means an environment pollution reduction and also a
reduction in fuel consumption if comparing with the values normally
higher.
Also we would like our satisfaction with the Thecnical Service that
offer , specially regarding the gas exhaust analisys , which help us on
the plant operation control .
Yours faithfully,
Signed : Benito Vicente Goyás
Co-generation [power] Plant Manager.
