1.5
2.
To pre-qualify various brands of Boiler Fuel Additives and their
manufacturers/suppliers for application in Boilers of SEC Power Plants burning
Heavy Fuel Oil. Dosing of the most suitable and appropriate Fuel Additive is
intended to protect the Heat Transfer surfaces from the corrosive and fouling
effects of the impurities present in the Heavy Fuel Oil by maintaining the pH of
ashes produced at the Electrostatic Precipitator (EP) outlet to ~ 3.5 at Air
Heater Outlet and Silo without any impact on the other operational parameters
of the Boiler.
To evaluate the performance of Fuel Additive in reducing Stack Emissions and
increasing combustion efficiency.
To determenie the effect of Fuel Additive on High & Low Tempreture Corrosion,
Rate of Fouling, Emissions (SO3, SO2, NOx, Particulate) and Acid Dew Point.
To determine the optimum Dosage Rate.
To investigate any adverse effects of the Fuel Additive on the Boiler
performance, such as efficiency, Fouling of Burners, Boiler tubes and plugging
of the Air Heaters.
METHOD SUMMARY:
 Supply of adequate quantitie(s) of potential Fuel Additive(s).
 Study of the present Fuel forwarding system and Fuel Additive dosing facility for
preparing arrangement drawings for Trial run set up clearly identifying the
equipment / instruments and temporary connections to the existing system.
 To make necessary arrangements including all measuring instruments and
conduct in situ Field Trial Test on the selected Boiler.
 Analysis of Test results and comparison of performance in repect of:
Maintaining the pH of Fly Ash ~ 3.5.
Free Acidity less than 1.0 % wt as H2SO4.
Improvement in Boiler performance by efficient combustion.
Reduction of fouling in the flue gas path components.
Minimization of emission pollutants.
Reduction of particulate emission
3.
COMMENTS:
 Supplier should submit references about their experience giving list of utilities
where their recommended brands of Fuel Additives are being used and Trial Test
carried out by them prior to the selection of the Fuel Additive. This should include
all details such as capacity / type of Boilers, date of commissioning, Fuel
characteristics, benefits accrued etc.
 It is understood that the expenses for Trial runs in connection with pre-qualification
of Fuel Additive e.g instruments, arrangment of test at site, analysis of results etc.
should be totaly borne by the Fuel Additive supplier. The agreed cost of Fuel
Additive shall be paid on quarterly basis if the test conducted yield successful
results during each quarter. However,
if the supplier has got alternative
options/scheme, the same may be submitted for SEC evaluation and consideration.

 All tests and associated works shall be carried out by supplier without causing any
damages to the equipment and perssonel of SEC and shall not anyway affect the
normal operation of the plant.
 The intent of whole exercise is only to pre-qualify Fuel Additive type/brand and
their suppliers. It does not any way confer rights on the Fuel Additive supplier for
the award of purchase order which shall be necessarily based on the merits of the
respective offers received.
 The offers complete in all details as elaborated herein shall be submitted in the
concerned office.
4.
TECHNICAL INPUTS:
 Our Boilers are designed to burn Crude Oil or Heavy Fuel Oil. The specificationn of
Arabian Light Crude and Heavy Fuel Oil, A-962 are attached.

currently. All the Trial runs should be designed to suit for the requirement of the
Fuel being used.
 The Boilers are equipped with Fuel Additive dosing facilites. However, supplier
shall arrange his own experts for samples analysis and carrying out the tests in a
reliable manner.
 To the extent possible SEC shall provide the available laboratory facility. However,
supplier shall arrange his own experts for samples analysis and carrying out the
tests in a reliable manner.
 The supplier should contact SEC for obtaining any design and operational details
of the Boiler which they feel deem necessary for the selection of the Fuel Additives
for FTT.
5.
PROCEDURE:
 Supplier should identify, techno-economically, from his product range the most
suitable Fuel Additive for achieving the specified objectives.
 The criteria for arriving at optimized Fuel Additive dosage rate, based on the Fuel
constituents such as Vanadium, Sulphur, Sodium, Potassium etc., should be very
clearly given together with procedures of calculation dosing rate and the theory
underlying behind it.
 Trial runs should be designed to suit the Heavy Fuel Oil currently in use.
 All the measuring instruments shall be calibrated for achieving necessary accuracy
of measurements. All details of instruments, procedures of calibration, actual
methods of measurement at site, measurement frequency together with
applicable standards shall also be provided to SEC.
 The duration of FTT are specified on page 7/11 of this Manual.
 It is foreseen that on use of the selected Fuel Additive for the 1 st quarter,
indications regarding its favorable effects get reflected; failing which test shall be
terminated. In case if the Trial runs prove to be successful with the dozing of the
Fuel Additive used in the first attempt, then the tests shall continue with the same
Fuel Additive till annual inspection.
 During Trial Testing, all the critical operating parameters shall be controlled by
Auto Mode of operation.
