Prominent Industry Pain Points Bottlenecking Thermal Power Operation

At present, domestic coal-fired units are generally confronted with operational challenges such as large peak-valley load differences and lagging coal type replacement. These problems not only restrict power generation efficiency but also raise coal consumption of high calorific value, becoming a core bottleneck restricting the economical and efficient operation of power plants.To tackle common industry pain points, DaTongLongYuan focuses on the core demands of deep peak regulation and economical blended combustion, and advances the upgrading and renovation of three major intelligent coal blending systems simultaneously. Through technological innovation, it empowers coal-fired power enterprises to cut costs, improve efficiency and accelerate green transformation.

Customized Intelligent Solution — Joint Project Built with Taizhou Power Plant

China Energy Taizhou Power Generation Co., Ltd. is a leading domestic ultra-supercritical coal-fired power enterprise. With advanced unit parameters and stringent environmental protection standards, it sets higher requirements for intelligent fuel management and efficient coal blending.

Undertaken by DaTongLongYuan, the intelligent coal blending system renovation project for Unit #3 of Taizhou Power Generation has innovatively built a high-precision intelligent coal blending network. By adding bidirectional conveying equipment and integrating self-developed anti-blocking technology, it realizes flexible switching and precise proportioning of coal types, effectively solving the technical difficulty of insufficient flexibility in the circulation of high-quality and low-quality coal in the industry.

Supported by Core Technology, Key Indicators Lead the Industry

The core technical indicators of the project have reached the leading level in the industry:

● Coal feeder metering accuracy: up to ±0.5%

● Full-process control accuracy: up to ±1%

● Adaptable to unit deep peak regulation, enabling rapid response to switching between peak load and peak regulation working conditions

Under the overall professional coordination and precise guidance of DaTongLongYuan, the project followed the principles of high-standard planning and high-efficiency progress throughout the construction. It strictly controlled construction safety, quality and schedule, and successfully completed the installation of anti-blocking devices for B/C/D coal bunkers, extended coal feeders and other equipment, as well as full-process work including overall system joint commissioning and performance verification. The project was completed with high quality on schedule and put into stable operation.

Intelligent Empowerment for Efficiency, Boosting Green and Low-carbon Transformation of Thermal Power

After full commissioning, the project has remarkably improved the unit’s coal type adaptability and load response speed, greatly reduced the consumption of high-calorific coal and cut power generation costs. Meanwhile, it optimizes combustion stability and environmental emission performance, injecting strong intelligent momentum for Taizhou Power Generation to build an intelligent fuel benchmark project and promote the green and low-carbon transformation of the power industry.

In the future, DaTongLongYuan will continue to delve into core technologies such as intelligent coal blending and anti-blocking & blockage clearing. With mature solutions and high-quality engineering services, it will help more coal-fired power enterprises achieve safe, efficient, economical and green operation, and contribute professional strength to the high-quality development of the energy industry.
