Damaged pipe, Cooling water leakage ⇒Steam Explosion
Most Important Monitor Point
ALARM( Leakage detected)A - B ( Flow rate difference) < Target ( Nor
mal )A - B ( Flow rate difference) > Target ( Abnormal )
High accuracy complies with reliable monitoring on cooling water leakage at tuyere!
A Suggestion at Tuyere of Blast Furnace
3
Differential Flow Rate ~ Strict Monitoring Standard~
Since cooling water leakage is very important factor to monitor, very small leakage must strictly be measured.
• A company in Japan Flow rate range: 0-800 L/min Targeted differential
flow rate: A - B <3 L/min Differential flow rate: Below than 0.375% of full scale
• B company in Korea Flow rate range: 0-500 L/min Targeted diffe
rential flow rate: A - B <5 L/min Differential flow rate: below than 1.0% of full scale
*) Accuracy of Electro-magnet Flow meter: ±0.5% of reading

Differential Flow Rate Monitoring ~ Field Trial ~
A Company – Result of Field Trial
Targeted Differential Flow Rate: 0.375% of F.S.
Result: 0.275%FS: Fully complied with severe monitoring standard!

Alarm Analyst - Correlation analysis
Correlation Analysis;-Easy to build Knowledge-Base alarm & event
model… unique technology
From alarm & event historical logs, Correlation Analysis extracts ;- Event groups consisted of the alarms and the operation
actions in a process upset Propagation path Source origin Nuisance alarms Total counts in Alarm & Event group Information about Alarm & Event group structure Cause & Effect relationship
– Cause of alarm flood or complex operation is estimated using order of events occurrence.
