  • Rotary Kiln Control System

1. Introduction to Rotary Kiln Control System

The rotary kiln intelligent control system is a full-process automation solution developed specifically for industries such as cement, metallurgy, and chemical engineering. The system adopts a DCS+AI algorithm architecture, integrating core functions such as temperature control, speed adjustment, and combustion optimization to achieve temperature control, energy saving, consumption reduction, and stable operation during the rotary kiln production process. It can increase output by 15%-30% and reduce coal consumption by 8%-15%.

2. System Architecture

1. Control Layer

DCS Control System: Using Siemens PCS7/ABB 800xA platform

PLC Redundant Control: Dual-machine hot standby at key points, MTBF > 100,000 hours

Interlock System: Complies with SIL2 safety level requirements

2. Detection Layer

Detection Items Technical Solutions Accuracy Level

Kiln Body Temperature Infrared Thermal Imager + Thermocouple Array ±1℃

Material Composition Online X-ray Fluorescence Analyzer 0.01%
