Accurate coal weighing is crucial for thermal power plants, directly affecting cost accounting, combustion efficiency optimization and overall economic benefits. Traditional belt scales often fail to maintain long-term high precision under complex power plant conditions (e.g., belt tension fluctuation, material impact, environmental interference) and require frequent manual calibration, which is time-consuming and labor-intensive.
To address this pain point, Guonuo Technology’s intelligent high-precision belt scale solution, supported by two core technologies — intelligent control and automatic bar code calibration — provides solid weighing guarantees for energy enterprises such as China Coal Lu'an Power Plant.
Intelligent Control: Stable Weighing in Dynamic Environments
Equipped with an adaptive intelligent control system, the belt scale uses advanced algorithms to real-time monitor key parameters (belt operation, material load distribution, instantaneous flow). It dynamically adjusts weighing model parameters to cope with disturbances like belt deviation or sudden flow surges, ensuring high stability and accuracy. Additionally, the built-in hydraulic neural deviation correction function keeps the belt running stably along the center line, eliminating the impact of belt displacement on weighing results.
Automatic Bar Code Calibration: Efficient Long-Term Precision Maintenance
Unlike traditional manual calibration (which requires shutdown and manual weight lifting, with cumbersome procedures and safety risks), Guonuo’s solution achieves full automation. A dedicated mechanical device automatically places high-precision standard bar codes on the scale for real-time online calibration during operation. Calibration data is collected, analyzed and reported automatically, ensuring long-term precision while reducing maintenance costs and operational risks.
Stably applied at key coal conveying points of China Coal Lu'an Power Plant, the equipment meets the strict requirements of refined fuel management. It effectively reduces weighing deviations and solves the problem of production disruption caused by manual calibration. Measured data proves it provides stable high-precision weighing data, becoming an indispensable cornerstone for fuel cost control and efficient operation.
Guonuo’s solution combines intelligent control and automatic bar code calibration to tackle complex industrial weighing challenges. It delivers high precision, stability and maintenance efficiency, providing practical value for energy industry customers.
