FOULING IN SUPERHEATER CASE STUDY
EVENT REPORTED by SAM GUARD®
SAM GUARD® detected a problem with process temperature of superheater in the boiler.
There was a continuous temperature increase over the last six months, with a difference of 100 Kelvin.
MAINTENANCE TEAM FINDINGS
Initial suspicion of clogging or dirt build up since it is located closer to the exhaust channel.
An internal maintenance report was made to do an on-site inspection and repair in case of deeper developing issues.
COST / DOWNTIME AVOIDED
Earlier alert helped with complete failure of the super heater.
“The plant team was surprised with this temperature increase, since this is not desired from an operational perspective and could cause serious temperature control issues in the boiler.”
