Post Retrofit /R & M Benefits

  • Installation of 7th mill (HP643) and connection of its PF pipes at the bottommost elevation “G” of firing system provided O&M flexibility in milling system and eliminated one of the reasons of generation loss.
  • This has become a reference for such R&M jobs in India, as this is “First of Kind” in any Indian Power Station.
  • Grinding elements of Sintered carbide have provided more than guaranteed life in existing XRP 623 mills & New HP 643 Mill .
  • Modified RAPH basket profile and metallurgy has resulted into improvement in boiler backend temp as compared to the pre R&M conditions. This has enhanced the boiler overall efficiency substantially.
  • The benefit due to lower backend temperature resulted in saving in fuel cost.
  • Existing relay based system is upgraded with Advanced Microprocessor based Control System which enhanced safety of boiler operation.
  • Work completed ahead of schedule in all 4 Units.
