METHOD AND INSTRUMENT FOR DETECTING BREAKAGE OF COOLING SYSTEM FOR FURNACE BODY IN BLAST FURNACE

摘要

PROBLEM TO BE SOLVED: To surely, quickly and accurately diagnose whether the breakage of a cooling system for furnace body in a blast furnace is developed or not, and a range of developed position.;SOLUTION: In a process, in which cooling drained water flowing out from respective outlets of a plurality of draining pipes 5 for cooling water in the cooling systems 1, 2, 3 for furnace body in the blast furnace is made to flow into a water receiving vessel, it is visually decided whether gas bubble is mixed in the cooling drained water or not. Then, when the mixed gas bubble is observed, this gas is recovered and CO gas component in the recovered gas is detected.;COPYRIGHT: (C)2002,JPO
