2. ALARM（Leakage detected)
A Suggestion at Tuyere of Blast Furnace
Blast Furnace
Arithmetic and Control Unit（DCS or Sequencer ） A
Entrance（Cooling water） B
Exit（Cooling water）
ALARM（Leakage detected)
A－B（Flow rate difference) ＜Target（Normal）
A－B（Flow rate difference) ＞Target（Abnormal）
High accuracy complies with reliable monitoring on cooling water leakage at tuyere!
Damaged pipe, Cooling water leakage ⇒Steam Explosion
Most Important Monitor Point

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: 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: L/min 　Targeted differential 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

4. Differential Flow Rate Monitoring ～Field Trial～
A Company – Result of Field Trial
Targeted Differential Flow Rate: % of F.S.
A (Entrance)
B（Exit）
A-B（DifferntialFlow rate）
Result: 0.275%FS: Fully complied with severe monitoring standard!

8. Alarm Analyst - Correlation analysis
Alarm Analyst R20
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.
