Client Overview
China Datang Corporation (China Datang), one of China’s five major state-owned power generation groups, operates a vast fleet of coal-fired power plants with a total installed capacity exceeding 150 GW. As the nation transitions toward cleaner energy while maintaining stable baseload supply, Datang continues to prioritize operational reliability, cost control, and environmental performance in its thermal power assets.
Project Background
Since 2017, BAO has partnered with China Datang to supply high-performance conveyor belts for coal handling and bottom ash removal systems at several large coal-fired power plants in Northern China. These facilities rely on extensive conveyor networks to deliver millions of tons of coal annually from storage yards to boilers and to transport ash away for further processing or disposal.
Client Challenges
In the high-volume, round-the-clock environment of Datang’s power stations, the material handling teams struggled with several key issues:
Heavy Continuous Loading
Coal conveyors operated at full capacity for extended periods, carrying abrasive fuel with varying moisture and impurity levels that accelerated cover wear.
Ash System Abrasion
Bottom ash, often sharp and gritty, quickly eroded belts in the slag removal lines, leading to frequent leaks and spillage.
Dust and Fire Risks
Fine coal dust created explosive atmospheres, while occasional hot spots demanded belts with reliable anti-static and flame-retardant properties.
Maintenance Windows
Strict regulatory and grid requirements left only narrow scheduled outage periods for repairs, making unplanned belt failures particularly costly.
The operations teams needed a supplier who could deliver consistently durable belts while responding quickly to urgent replacement needs.
BAO's Tailored Solution
After thorough review of Datang’s conveyor specifications, coal characteristics, and ash handling conditions, BAO proposed a targeted range of heavy-duty EP fabric core conveyor belts:
Abrasion-Focused Design
Cover rubber optimized for low abrasion loss (<150 mm³ target grade), significantly outperforming DIN 22102 standards to extend life in both coal feed and ash removal applications.
High Tensile Strength
EP 500–630 N/mm configurations with ply adhesion >4.5 N/mm and tensile strength >18 MPa, providing the robustness required for long overland runs and high-throughput systems.
Safety Compliance
Anti-static and flame-retardant properties built in to meet power industry safety regulations and reduce dust ignition risks.
Flexible Customization
Options for sidewall and cleated designs on inclined sections, plus fast-delivery stock for critical spare belts.
BAO’s team worked hand-in-hand with Datang engineers to fine-tune belt selections, supplying detailed technical data and rapid sample turnaround to accelerate approval and deployment.
Implementation and Support
BAO coordinated deliveries to align precisely with planned outages, ensuring no delay to unit restarts. On critical replacements, we provided emergency splicing teams and 24/7 technical hotline support. Comprehensive training sessions were held for plant maintenance crews, covering proper tensioning, alignment checks, and early detection of wear patterns specific to power plant conditions.
Results and Impact
The switch to BAO belts brought immediate and sustained benefits:
Significantly Longer Belt Life
Average service life in coal handling systems improved by 35–40%, while ash conveyor belts lasted over 50% longer than previous suppliers.
Reduced Spillage and Cleanup
Better cover durability minimized material leakage, lowering housekeeping time and environmental compliance risks.
Lower Overall Costs
Fewer replacements and less unplanned downtime translated into meaningful annual savings across the plants.
Operational Confidence
Maintenance teams reported greater peace of mind knowing belts could reliably handle peak load periods.
This growing partnership demonstrates BAO’s strength in providing practical, high-quality conveyor solutions that help major power generators like China Datang maintain stable, efficient, and safe operations. We look forward to extending support to additional units and exploring further optimizations together.
