Recommendations of 9th KT Meet

The draft recommendations from the 9th KT meeting include inspection protocols for SH and RH headers before COD and in older units, strict maintenance of boiler chemistry parameters, and changes in identifying tube leakage in RH. Additionally, it suggests checking the thruness of circuits during overhauls and standardizing specifications for grinding elements in tube mills. These measures aim to enhance operational safety and efficiency in boiler systems.

DRAFT RECOMMENDATIONS OF 9

TH
KT MEET

1) Inspection of SH and RH headers to be carried out before
COD, preferably before steam blowing in new units.
2) In older units also, all headers of SH and RH to be
inspected once for any foreign material/debris.
3) Boiler chemistry parameters to be strictly maintained as
per OD issued from CC-OS.
4) Identification of tube leakage in RH by vacuum pulling to
be stopped. Tube leakage in RH to be identified by
pressurizing RH with air. Schemes for air pressurization to
be made.
5) Thruness of SH/RH circuit where tube is being replaced, to
be checked by sponge ball test during OH and in case of
tube failure due to overheating or failure inside
penthouse. In case of other failures, thruness of bottom
bend to be checked by removing bend from position.
6) Standardization of specifications for procurement of
Grinding elements of tube mills.
