DEVICE FOR DETECTION OF INJURIES OF COOLED MEMBERS OF BLAST FURNACE Russian patent published in 1996 - IPC

FIELD: metallurgy. SUBSTANCE: invention relates to detection of injuries of cooled members of sets of evaporation cooling under low pressure of steam in system. Device for detection of injuries has heat exchanger connected to drum-separator to accumulate blast furnace gas coming through leakages into circulating water and water-cooled coil pipe placed inside heat exchanger to ensure condensation of water steam. When vessel is filled with blast furnace gas heating of water cooling coil pipe stops which is symptom of leakage of blast furnace gas into system of evaporation cooling and establishes fact of injury of cooled pipes of coolers or large-unit panels. EFFECT: improved reliability of device. 1 dwg
