Abstract

There were many cases of girdling loop failures in the reheater section of the 500 MW boilers of athermal power station after being in service relatively for a short period of a few months. Within seven months of synchron-ization, the bottom 'U'portion of the front reheater
girdling loop of the boiler of 500 MW thermal power
plant had developed a leak. The plant was restarted
alter replacing the failed protion of the type 304 stain-less steel 'U' tube. Failure occurred again within seven
months of operation. Similar failures followed in the other units of the station.
