Energy requirements for various pelletizing systems are considered from a fuel and power aspect, with the presentation of typical energy heat balance flow sheets. A partial calculation for the firing zone of a straight grate system is shown and a comparison of an actual measured and a theoretical-calculated heat balance for a grate-kiln is presented. The power used for each pelletizing system and future possible energy savings are also reviewed.
