Experimental data were always taken as the
basis, and were recorded in Cogeneration Plants with Diesel engines running
on fuel oil; many years were spent collecting comparative data; long-term
monitoring programmes were carried out in conjunction with the proprietors
and the engine manufacturers. rb bertomeu S.L. developed
a methodology to produce the Profitability Study for the application of
additive treatment to fuel oil with “rb bertomeu”
beco F1/ASF in order to improve its performance. The
methodology and the calculations, applicable to any plant, are based on the
1. Cost of the additive treatment of the
fuel oil, with the additive “rb bertomeu” beco F1/ASF,
taking into account the price of the additive and the necessary dosage.
2. Price of fuel oil supply.
3. Price of replacement exhaust valves
for the engines.
4. The more significant proven
savings provided by the
4.1 – Reduction in consumption of fuel oil (2.4 to 3.1 %)
4.2 – Statistical Reduction in consumption of replacement valves (minimum
4.3 – Increase in electricity generation due to fewer stoppages (plants in
With these savings alone,
the calculation results in a Nett Benefit of 1.4 Euros per MWhe
produced in the Plant, when
assuming a price for fuel oil of 180 Euros per metric tonne and a cost for
the additive treatment of 0.625 Euros/MWhe (maximum cost charged for small
Other real savings are enumerated, but not
evaluated or introduced in the calculation, as these are more specific to
each Plant or sufficient cost data are not available. The main factors that
could be applied to each Plant by reworking the calculations, applying
their particular costs and prices, are the following:
- Reduction in costs of removal and treatment of
fuel oil sludge (minimum 50%).
- Reduction in costs of replacements for
Turbo-compressors, due to the increase in their operational life by
- Greater production of steam in associated
boilers, as the heat exchangers keep cleaner.
