In the vast operational system of thermal power plants, the stable, efficient, and precise metering of coal combustion is not only crucial for fine control of power generation costs, but also serves as an important cornerstone for settlement, calorific value calculation, positive balance power generation efficiency measurement, and even energy consumption statistics under the "dual carbon" goals. However, traditional belt scales often encounter accuracy bottlenecks when dealing with the vast and complex working conditions of power plants, becoming an invisible barrier that restricts fine management.
It is against this backdrop that Guonuo Technology's AI high-precision belt scale weighing system was born. It not only meets the power plant's demand for large-scale metering of coal combustion but also achieves a metering accuracy of up to 0.2%, providing solid technical support for the sustainable development of the power industry.
Guonuo Technology's AI high-precision belt scale weighing system deeply integrates cutting-edge AI algorithms and precision sensing technology, revolutionizing traditional metrology models:
1. Core of dynamic compensation empowered by AI:
- Intelligent perception: The system collects and analyzes massive real-time operational data, including belt tension changes, belt deviation status, instantaneous flow fluctuations, environmental temperature and humidity, etc.
- Deep learning model: The built-in powerful AI model continuously learns from historical data and error patterns, establishing a nonlinear mapping relationship between complex working conditions and measurement errors.
- Real-time dynamic correction: With millisecond-level response, intelligently correct and compensate for each instantaneous weighing signal, actively offsetting errors caused by various interference factors.
- Online calibration: In view of the continuous production in power plants, where frequent downtime for calibration is not feasible, automatic online calibration can be achieved through standard rod codes and intelligent algorithms. This not only enhances the stability of coal conveyor line measurement but also ensures the continuous and stable production of thermal power plants.
2. Breaking through the limit with a high precision of 0.2%:
In the actual operating environment of a power plant, facing large flow impacts of hundreds or even thousands of tons per hour, the system can still maintain a metering accuracy better than 0.2% stably.
This accuracy is not only a theoretical value, but has also been rigorously verified in the long-term operation of multiple large coal-fired power plants (such as the coal handling system of a 2×1000MW ultra-supercritical unit power plant), and is far superior to the 0.5%-1% belt scale accuracy level required by national standards.
3. Suitable for the characteristics of coal combustion in power plants:
- Wear-resistant design: Key load-bearing components are made of special wear-resistant materials and crafted using specialized techniques to withstand the strong abrasive properties of coal combustion.
- Strong anti-interference capability: The sensor and signal processing circuit possess excellent resistance to vibration and electromagnetic interference, adapting to complex on-site electrical environments.
- Temperature adaptability: The design of a wide temperature range ensures measurement stability under extreme cold and heat conditions.
- Intelligent diagnosis and early warning: The AI system also undertakes the responsibility of equipment health management, providing early warnings for belt abnormalities, instrument zero drift, potential faults, etc., to prevent problems before they occur.
In a large power plant, the original metering system had significant deviations and fluctuations, leading to distorted coal consumption data and difficulties in internal accounting. Guonuo Technology's AI high-precision belt scale was deployed at key metering points on the main coal conveyor belt, stabilizing the metering accuracy of as-fired coal at ±0.2%. This has brought significant benefits to the power plant's production and economy:
The settlement data is clear and transparent, effectively reducing business frictions;
Based on accurate coal consumption data, the reliability of positive balance power generation coal consumption calculation has been significantly improved, providing a solid basis for operational optimization;
Accurate energy consumption data provides strong support for carbon emission accounting and energy conservation and carbon reduction target management in power plants.
Guonuo Technology's AI high-precision belt scale system has surpassed its role as a mere measuring tool. Empowered by cutting-edge AI technology, it brings precision leaps, reliability guarantees, and intelligent innovations in the field of coal measurement to the energy and power industry.
With a precision guarantee of 0.2%, it directly addresses the core demands of large-scale, high-precision coal measurement in power plants, solving long-standing pain points that have plagued the industry. It provides solid data support for refined operations, cost control, environmental compliance, and even production decision-making in thermal power enterprises.
