Optimization of Furnace Combustion Control System Based on Double Cross-limiting Strategy
Furnace as the key equipment and a big energy consumer of the steel industry, its combustion control performance directly affects the quality of steel products as well as the energy consumption of equipments, etc. So, the control technology of the furnace combustion becomes one of the important research topics in the iron and steel enterprises. Based on the original furnace temperature-combustion cascade control system in a special steel plant, this paper focuses on optimal designing and improving of the furnace combustion control loop via the cross-limiting control strategy. After the double cross-limiting control of gas and air flow based on air-fuel ratio is introduced, the control performance of the original system is greatly improved and the energy consumption and environmental pollution are reduced.
