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.
