Loop Optimization Control Design and Programming for Cement Grate Cooler

For purpose of optimizing the control performance and technology performance of the grate cooler system manual regulation loop. Based on Cimplicity 6.0 configuration software and Concept 2.6 programming software of DCS,loop optimization control of the grate cooler first velocity PID,the grate cooler second velocity proportional adjusting,kiln head exhaust fan velocity PID,adjusting valve position PID of cooling machine air damper were designed and realized. Undisturbed switching of manual and automatic control was realized. The results of adjusting and trial operation show that the thickness on the grate cooler bed was supported effectively,cement clinker cooled homogeneous,entered kiln secondary air stability,grate cooler safety running,meet the demand of technological properties,achieve the anticipated goal of optimization control.
