2ALARM（Leakage detected) A Suggestion at Tuyere of Blast FurnaceBlast FurnaceArithmetic and Control Unit（DCS or Sequencer ）AEntrance（Cooling water）BExit（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 ExplosionMost Important Monitor Point
3Differential 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 JapanFlow rate range: L/min Targeted differential flow rate: A－B＜３ L/minDifferential flow rate: Below than 0.375% of full scaleB company in KoreaFlow rate range: L/min Targeted differential flow rate: A－B＜５ L/minDifferential flow rate: below than 1.0% of full scale*) Accuracy of Electro-magnet Flow meter: ±0.5% of reading
4Differential Flow Rate Monitoring ～Field Trial～ A Company – Result of Field TrialTargeted Differential Flow Rate: % of F.S.A (Entrance)B（Exit）A-B（DifferntialFlow rate）Result: 0.275%FS: Fully complied with severe monitoring standard!
