Belorado, June 2015

 

Minera de Santa Marta, S.A. owns a cogeneration power plant producing 18.75 MWhe at its facilities in Belorado (Burgos), equipped with three engines type DEUTZ MWM BV 16M 640, which opened in early 1995.

 

Since April 1995 it has been using the engine fuel oil additive "rb bertomeu" beco F1 / ASF, for the treatment of fuel oil consumed in the plant.

 

During the first 36,000 hours of operation we made several tests of the effectiveness of the additive "rb bertomeu" with full satisfactory results which led us to use the above mentioned additive ever since.

 

We authorise the use of this letter for reference purposes.

Belorado, 25th August 1999

Dear Sir,

In reply to your request, we are pleased to express the full satisfaction in our factory with the benefits obtained from the use of the "rb bertomeu" beco F2/A additive which we add to the fuel  oil used (nº2) in our pirotubular boilers.

The improvements observed are:

1.   Important decrease in the number of pipes blocked by soot, increasing the interchange surface of the boiler.

2.   Reduction of the hardness of the little encrustation that appears in the pipes, clearly reducing the cleaning time employed.

3.   Removal of the encrustation of unburned fuel that appears in the burners, easing inspection, cleaning and improving the condition of the burners.

Also, we would like to express also our satisfaction with the Technical Service supplied to us.

We authorise the use of this letter for reference purposes.

Belorado, 1st August 1998

Dear Sir,

In reply to your request, having reached 25,000 - 26,000 operation hours of 3 Deutz engines installed in our Cogeneration Plant in Belorado, we are pleased to express the our satisfaction in our factory with the benefits obtained by the use of your rb bertomeu additive, which we have been adding to the fuel oil (nº 1 Bia and nº 1) for exactly 3 years (August/95 - August/98).

In addition to the already detected improvements regarding the reduction of fuel oil sludge, we would like to emphasise the following achievements observed and quantified during this period, regarding the conservation of the engine valves:

·      Total absence of corrosion in the inlet valves of the 3 engines, none of them having been replaced for this reason (only 3 have been changed because of  mechanical misadjustment, which represents 3.1 % of the total installed)

·      Practical elimination of corrosion in the exhaust valves of the 3 engines, only 4 valves have been replaced for this reason (4.2 % of the total valves installed)

·      Notable total increase of the useful life of the exhaust valves, which practically doubles the value estimated by the manufacturer. Currently, 60% of the valves and 84% of the original valve baskets are in service, the remainder having been replaced gradually due to thermal fatigue or by not reaching the necessary minimum measures, as of approximately 20,000-21,000 operation hours.

Also, we would also like to express our satisfaction with the Technical Service that offer, especially referring to the inspections of the engines, whose technical and photographic reports constitute a valuable element for the follow-up and statistical control of the  evolution  of the  maintenance  of our engines.

We authorise the use of this letter for reference purposes.

Aranjuez, June 26th 2015

Dear Sir,

Our cogeneration power plant of 12.6 MWh. Equipped with two Deutz MWM type BV 16 M 640 engine was inaugurated in early February 1996.

Since mid-April 1996 until the time of closure of the plant in January 2011 for fuel oil additive engine "RB BERTOMEU" beco F1/ASF was used for the treatment of fuel consumed in the plant.

During the 15 years of operation of the engines, the most important benefits that provided the additive "BERTOMEU RB" were:

·   The Neutralization of corrosion and fouling waste exhaust valves and turbochargers than doubled the life of valves and turbos.

·   Increase The service factor for the increase of TBO (time between overhauls) for the longer duration of the exhaust valves and turbochargers.

We authorise the use of this letter for reference purposes for your products and services.

Madrid 30th January 2001

Dear Sir,

We certify that in the Ufefys co-generation plant, located in Aranjuez (Madrid), we have been using “rb bertomeu” additives for fuel oil regularly and without interruption since the beginning of 1996.

After nearly 5 years of using these additives in our fuel oil, especially beco F1/ASF, we are pleased to show our total satisfaction with the technical and economic results obtained from the two DEUTZ engines, type BV 16M 640, in the plant.

As we have said before, the use of “rb bertomeu” additives to treat fuel oil has given us a notable economic benefit through the basic points which are a consequence of various actions on the process:

·      A saving in maintenance due to the great reduction of corrosion in exhaust valves and no corrosion in turbos and inlet valves.

·      An increase in the service of the plant due to the lower number of maintenance and cleaning stoppages, and an increase in the TBO (time between overhauls) made possible by the longer life of the exhaust valves.

The long period of production that the plant has had using these additives is a guarantee, as we understand it, of their quality for this kind of installation.

As on previous occasions, we authorise the use of this letter for reference purposes for your products and services.

Dear Sirs,

 

In reply to your request we certify trhough the present letter,  that since several years ago we are using the fuel oil additive “rb bertomeu” beco F2/A  , manufactured and supplied by your company. The obtained results , technical and economical, are satisfactory in our factory of Maderuelo (Segovia).

 

In that factory we use fuel oil nº 1  as fuel , treated with the above mentioned product beco F2/A.

 

Our installation of combustion has the following characteristics :

 

            Dryer for clays  ,  type Fluidized vibrating bed

            Equipped with a burner Pillard type of 5000 T/h .

 

We authorise the circulation of this letter as a reference for any purpose.

25th January 1999

Dear Sir,

In reply to your request with respect to the certification of the efficacy of your additive service which we have been using since September of 1.997, we would like to show the following facts which we authorise for reference purposes: 

A - Our cogeneration plant is equipped with 2 DEUTZ MWM engines, type TBD 645 L9, with a power of 3,5 Mwe  each one. The engines were put in operation in April - 96 and are using fuel oil nº 1 BIA as fuel.

B - After some adjustments in the operation of the installation carried out between the implementation and the June ’97 inspection, we decided to prevent the corrosion problem of the exhaust valves of the present engines from the beginning of operation.  To this end, knowing the results obtained in the cogeneration plant of MSM, belonging to our Business Group SAMCA, we decided to contract the services of rb bertomeu S.L.

C - Since we began the additive treatment in September - 97 of fuel - oil Nº BIA “rb bertomeu” products beco Mg and later “rb bertomeu” beco F1/ASF, practically all the corrosion problems previously cited have disappeared, which has produced a great saving in maintenance and repair time.

Also we note the disappearance of the serious residual encrustation that was produced in the exhaust valves as well as in elements of the exhaust gas circuit.

D - Finally, we appreciate the technical collaboration that we have received, through assistance in engine inspections, analysis of combustion gases, compilation of follow-up information, etc., all immensely useful for our plant management.
