WHAT IS AN INDURATING FURNACE - IDC-Online

In an Indurating Furnace, the pellets are loaded on to a travelling grate to a depth of approximately 3060cm where they are preheated (typically to 800- 9000C), before entering a - higher temperature stage (around 1,200-1,3500C) which in some designs is a continuation of the travelling grate, and in others take the form of a rotary kiln.

AbstractDuring induration in a straight grate machine, the green pellets pass through four different thermal treatments, namely drying, preheating, heating and cooling. The pellet bed is fired with downdraught firing leading to thermal gradients through the bed. Corex sludge, which is used as fuel in the pellet mix, supplies the necessary energy for uniform heating of the pellet.
