coal based direct reduction rotary kiln process ispatguru

coal based direct reduction rotary kiln process ispatguru

Feb 14, 2017 · Fig 1 Cross section of rotary kiln. Coal based direct reduction process is based on the solid reducing agent which is non-coking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired

radiative heat transfer conditions in a rotary kiln test

radiative heat transfer conditions in a rotary kiln test

This work studies the radiative heat transfer in a 580 kWth pilot scale test furnace that resembles a full-scale rotary kiln for iron ore pellet production. The aim is to quantify the radiative heat transfer in coal and cofiring flames and also to study the possibility to model the radiative heat transfer for such combustion conditions. Three combustion cases of coal and cofiring are studied
