                Use Of
       Super Critical Technology
• Supercritical Technology is widely established and
  accepted with more than 500 units in operation.
• Widely prevalent cycle parameters:
   – Pressure: 246 -250 kg/cm2
   – Temperature: 538/538 deg C
             »      538/566 deg C (Sipat & Barh TPS)
             »      566/593 deg C (Mainly in Japan &
                    Germany)
             »      593/593 or 600/600 deg C
• Preferred steam parameters include higher steam
  temp. of 566 to 593 deg C depending upon site specific
  techno-economics. BHEL collaboration includes these
  parameters.

                                               Contd.

  Option of using Washed Coal
• Indigenous coal generally have high ash content, wide
  variation in calorific value, presence of extranous
  matter and is unsized.
• Considering large unit size, it is desirable to have good
  and consistent coal quality, free of extraneous matter
  with a view to
   – Narrow down coal design range
   – Less wear and tear of coal handling and coal
     pulverizers
   – Reduced teething problems in initial stage of
     technology introduction
   – Comfort in plant operation
             CONCLUSION
•   A MAJOR SHARE OF CAPACITY ADDITION EXPECTED
    THROUGH LARGE SUPERCRITICAL UNITS IN ULTRA
    MEGA PROJECTS AND OTHER 800 MW SIZE UNITS BY
    NTPC, APGENCO & OTHER UTILITIES.

•   HIGHER STEAM PARAMETERS IN SUPERCRITICAL UNITS
    PREFERRED FOR BETTER EFFICIENCY.

•   FOR OVERALL ECONOMICS, PITHEAD STATIONS CAN BE
    INTEGRATED WITH COAL WASHING AND CFBC UNIT TO
    USE WASHERY REJECTS.

•   DESIRABLE TO HAVE TECHNOLOGY TRANSFER WITH
    INDIGENOUS MANUFACTURING CAPACITY BUILDING TO
    MEET THE PROJECTED CAPACITY ADDITION TARGETS
    WITH ADEQUATE COMPETITION.
