Ⅰ. System introduuction Tuyere remote monitoring system 1. System outline Blast furnace and Corex process made molten iron have several tuyres to circle direction at bottom level, supply high temperature combustion air and pulverizing coal through tuyeres. It will produce molten iron by making conbustion at high temperature through tuyeres. Tuyeres of main process will be always observed through pipe line by operator at site and automatic remote monitoring. Video camera unit will be installed at tuyere end and operator can observes inside tuyere through it and digital video processor unit will be installed, convert video signal by digital transmission unit and operator can see normal or abnormal condition inside tuyere through visual monitor at operating room and all tuyere conditions can be seen. • Conbustion condition monitoring - Real time tuyere video remote display • Tuyere condition monitoring - Lance distortion status monitoring - PC injection monitoring - Tuyere leakage automatic monitoring - Tuyere bending monitoring • Abnormal Tuyere alarm function -6 -
