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 steamtemp. of 566 to 593 deg C depending upon site specifictechno-economics. BHEL collaboration includes theseparameters.

Option of using Washed Coal

Indigenous coal generally have high ash content, widevariation in calorific value, presence of extranousmatter and is unsized.

Considering large unit size, it is desirable to have goodand consistent coal quality, free of extraneous matterwith a view to

Narrow down coal design range

Less wear and tear of coal handling and coalpulverizers

Reduced teething problems in initial stage oftechnology introduction

Comfort in plant operation

CONCLUSION

A MAJOR SHARE OF CAPACITY ADDITION EXPECTEDTHROUGH LARGE SUPERCRITICAL UNITS IN ULTRAMEGA PROJECTS AND OTHER 800 MW SIZE UNITS BYNTPC, APGENCO & OTHER UTILITIES.

HIGHER STEAM PARAMETERS IN SUPERCRITICAL UNITSPREFERRED FOR BETTER EFFICIENCY.

FOR OVERALL ECONOMICS, PITHEAD STATIONS CAN BEINTEGRATED WITH COAL WASHING AND CFBC UNIT TOUSE WASHERY REJECTS.

DESIRABLE TO HAVE TECHNOLOGY TRANSFER WITHINDIGENOUS MANUFACTURING CAPACITY BUILDING TOMEET THE PROJECTED CAPACITY ADDITION TARGETSWITH ADEQUATE COMPETITION.
