SUCCESSFUL APPLICATION OF MODEL BASED PREDICTIVE CONTROL FOR PRODUCTION AND THERMAL EFFICIENCY OPTIMIZATION OF HIGH TEMPERATURE MELTERS

摘要

In the past decade, advanced multiple input/multiple output (MIMO) process control systems have found their way into high temperature melting processes. Today a growing number of high temperature melters have been equipped with a supervisory control system. Daily regulation of fossil fuel firing and electric energy supply to stabilize temperatures is no longer in the hands of the operator, but fully taken over automatically by the ES III™ MPC controller, which provides consistent process control, 24 hours per day, focused to operate the entire glass production process in the most efficient way. The presentation will show practical results and benefits achieved in the high temperature glass and cement industry.
