Digitalized Coal Blending Boosts Energy Conservation and Carbon Reduction

Recently, the intelligent coal blending project for Unit 3 Boiler of Zhejiang Zheneng Yueqing Power Co., Ltd., undertaken by DaTongLongYuan, has fully finished on-site commissioning after comprehensive procedures including scheme refinement, equipment installation, system joint debugging and working condition testing. The system is now ready for stable official operation. The successful delivery of this project realizes the full digital and intelligent upgrading of coal blending modes at Zhejiang Zheneng Yueqing Power Plant, and fully demonstrates the robust technical strength of DaTongLongYuan in the fields of intelligent coal blending and deep peak regulation optimization for thermal power units.

As a core upgrading initiative for energy efficiency improvement and green transformation in the power sector, this project adopts a coal blending process combining linked coal feeder transportation and intelligent logic regulation. Supported by equipment linkage and automatic programs, it achieves precise blending and conveyance of various coal types, enabling dynamic adaptation to real-time operating conditions of the generating unit.

To address prevalent industry pain points: risks of coal bin distortion or even falling off caused by unbalanced material levels on both sides of partitioned bins leading to uneven bin loads, as well as coal spontaneous combustion and caking arising from coal accumulation outside the shrimp-bend bins, customized optimizations were carried out across three dimensions: equipment structure, operation workflow and control strategy. The solution completely eliminates the above recurring faults and effectively overcomes the drawbacks of traditional partitioned bin modes such as frequent coal blockages and uneven coal mixing.

Furthermore, the implementation process requires no modifications to the FSSS main protection and original control logic. The unit’s AGC automatic generation control system and air-coal ratio adjustment functions remain fully operational. Data on fuel consumption statistics and unit economic performance analysis are complete and accurate, fully guaranteeing the stability and reliability of the unit’s original operation system.

Forging Ahead to Advance Thermal Power Transformation

The smooth handover of this project marks another key achievement of in-depth cooperation between DaTongLongYuan and Zheneng Group, as well as another successful application of the company’s intelligent coal blending technology on mainstream thermal power generating units.

Throughout the whole process from scheme design, technical adaptation and equipment deployment to on-site commissioning and delivery, the DaTongLongYuan project team adhered to high standards and strict requirements. It accurately aligned with on-site working conditions and efficiently resolved various technical challenges. With professional technical capabilities, mature solutions and high-quality delivery services, the team completed the project handover excellently and won high recognition from the client.

Looking ahead, DaTongLongYuan will continue to deepen its presence in intelligent thermal power and energy conservation & carbon reduction sectors. The company will iteratively upgrade core technologies for intelligent coal blending and deep peak regulation optimization. Drawing on extensive project delivery experience, it will provide customized, integrated digital and intelligent solutions for more power enterprises. The company strives to support traditional thermal power industries in improving quality and efficiency, accelerating green and low-carbon transformation, and contribute to the development of a new-type power system.
