2- SAVINGS FROM THE USE OF THE ADDITIVE

(The savings from less breakdowns and less need for servicing have not been quantified, this has to be done by the client using the appropriate plant data and the savings percentage supplied by rb bertomeu SL in each case)

2.1   Average fuel saving of 3% (5)
       (Average fuel cost =  FC   Euro/Tm)

: 0,01476xFC Euro/MWhe (2)

2.2  69% saving in replacement of exhaust valves shafts compared to the normal
        replacement level (6)
       (average price in Euro/unit and saving to be defined by client)

: a1      Euro/MWhe

2.3  85% saving in reconditioning of valve seats in the head or exhaust valve baskets
       compared to the normal replacement level (6)

       (average price in Euro/unit and saving to be defined by client)

: a3      Euro/MWhe

2.5  Saving in stoppage time due to fewer number of breakdowns and increased
       T.B.O., which raises the service factor  (7)

: a4      Euro/MWhe

       Total saving in maintenance of exhaust valves (6,7,8)

                           A = a1 + a2 + a3 + a4

: A      Euro/MWhe (3)

2.6  Saving in replacements and maintenance due to less corrosion in turbocompressors
       (blades, rotors and body), equivalent to 25-50% of the normal cost in pieces and
       repairs

: b1      Euro/MWhe

2.7  Saving in stoppage time for maintenance and cleaning, equivalent to 25-40% of the
       normal time, which raises the service factor

: b2      Euro/MWhe

       Total saving in maintenance of turbocompressors  (9)

                            B = b1 + b2

: B      Euro/MWhe (3)

2.8  Total saving per MWhe produced
