Abstract

Optimal control of heating furnaces requires temperature-thermal mode correction with respect to actual heating conditions. Conditions are by far the most influenced by irregularities during furnace heating material withdrawal. Time flow corrections settings of required temperature values in single furnace zones is possible to optimize based on heating models prediction. Furnace temperature values play the most important role during heating simulations. However, the influence of an instant heating gas flow in nozzles within singe parts of a furnace cannot be underestimated. The article shows the way to define time trajectories of actuating variables and identification process itself, based on the identification and consequent simulation. Achieved results should be exploited for various heating ways generating, followed by optimal alternative choice.
