NO SHOW: Safe Operating Strategy of Post-Combustion Chamber for Optimal Energy Utilization in a Sponge Iron Plant

In a direct reduced iron (DRI) plant, the post-combustion chamber (PCC) receives the waste gases from the rotary kiln. The gases, at 1,073 K or higher, enters the PCC with unburnt carbon monoxide and coal, ash, and dust. Uncontrolled combustion combined with dust deposition inside the PCC can lead to an explosion. Safe operating practice (SOP) for the PCC is developed by using the combined material and energy balance of the rotary kiln and PCC for the first time. One case of an explosion in the PCC is analyzed. The cause of the explosion is analyzed and is linked to the sudden dislodging of deposits.
