Description
1. Real – world Case
In a large – scale cement manufacturing plant, the 3BHE035301R1002 was integrated into the control system of a cement kiln. The cement kiln is a key piece of equipment in the cement production process, where raw materials are heated at high temperatures to produce clinker.
One day, during the normal operation of the kiln, the sensors detected a significant change in the temperature distribution inside the kiln. This could potentially lead to uneven burning of the raw materials and affect the quality of the clinker.
The 3BHE035301R1002, which was connected to these sensors and the burners’ control valves, immediately received the temperature data. It quickly analyzed the data using pre – programmed algorithms and compared it with the optimal temperature profiles.
Based on the analysis, the 3BHE035301R1002 sent control signals to the burners’ control valves. It adjusted the fuel flow rate and the air supply to different burners to re – balance the temperature distribution inside the kiln.
Thanks to the timely and precise control of the 3BHE035301R1002, the temperature inside the kiln was restored to the normal range within a short time. The quality of the clinker was maintained, and the overall production efficiency of the cement plant was ensured.
