On-line optimization of induration of wet iron ore pellets on a moving grate

摘要

The present invention discloses a system for optimizing the operation of an induration furnace and a method thereof; the system comprising: an interactive means to monitor and control the furnace to provide an optimized furnace operation, calibration means for generating a plurality of ideal set points for validation purposes, and a processing unit receiving, in real-time, the online process data from the interactive means and compute therein a plurality of real-time active set points which are matched with corresponding ideal set points from the calibration means, wherein, if optimization is required, an optimizing signal is generated and communicated to the interactive means. The system predicts in real-time the process and product parameters, that cannot be measured directly, thus, providing real-time optimization of the furnace operation, and thereby reducing the operating and production costs.
