Non-linear State Estimator for the On-line Control of a Sinter Plant

Abstract

This is a thermal control model that aims to increase sinter process stability and standardize control criteria using the position and temperature of the sintering point or BTP calculated by the model. The process computer sends to the instrumentation setpoints of return fines, strand speed and coke content. The model was successfully tested at the facilities of AM Asturias with contrasted improvements in productivity, cok consumption and quality stability.
