Control of Bum-through Point for Agglomeration Belt

摘要

The paper describes the control of burn-through point for sinter on the agglomeration belt. This control is based on mathematical modelling of agglomeration process. The mathematical models and algorithms are derived from basic models of physical and chemical processes of agglomeration belt and they are based on directly and indirectly measured quantities of agglomeration belt. The feed-forward control is based on the quantity of the gas combusted in the ignition furnace and on the quantity and composition of the raw mix. This value is corrected according to the identified burn-through point. Output from the control system is the required value of turbo-exhausters operating speed.
