In Sponge Iron Plants the kiln outlet gases are at approx. 900 to 950 °C. These flue gases cannot be let out to atmosphere as it is and are to be de-dusting. Hence, it is mandatory to provide Dust Collecting system. The major problem of providing the Dust Collecting System is the temperature of the flue gases and it becomes necessary to cool the kiln exhaust gases to around 180 to 220 °C.
