Located in the northern region of France, the Lille power plant is a thermal facility that generates electricity by burning coal. The combustion process produces a substantial amount of fly ash, a fine particulate residue that must be collected and transported to storage silos or disposal sites. Traditionally, mechanical conveyors such as belt conveyors or screw conveyors were used, but they suffered from high maintenance costs, dust leakage, and limited flexibility. To address these challenges, the plant management decided to implement a modern pneumatic conveying system. After a thorough evaluation of international suppliers, Shandong Headpowder Engineering Co., Ltd. was selected to design, manufacture, and install the entire pipeline pneumatic conveying system. This case exemplifies a typical pneumatic conveying case in the European energy sector, demonstrating the reliability and efficiency of headpowder technology.
The fly ash pneumatic conveying system at the Lille power plant is a dense-phase positive pressure pipeline conveying system. The design capacity is 40 tons per hour, with a conveying distance of approximately 850 meters from the ash collection hoppers to the main storage silos. The pipeline diameter is 200 mm, made of abrasion-resistant steel to withstand the erosive nature of fly ash. The system uses a series of pressure vessels (blow tanks) operated by compressed air at 0.6 MPa. The conveying velocity is controlled between 4 m/s and 8 m/s to maintain a stable material-to-air ratio, ensuring efficient transport without pipeline blockages. This France pneumatic conveying installation is notable for its high reliability and low energy consumption. The system is fully automated, equipped with pressure sensors, flow meters, and PLC controls that continuously monitor the conveying process. The Lille pneumatic conveying project required careful adaptation to the existing plant layout, which involved multiple bends and elevation changes. headpowder engineers optimized the pipeline routing to minimize pressure drops and wear points, resulting in a smooth operation that has been running for over three years with minimal downtime.
The core components of the pipeline pneumatic conveying system include the rotary airlock feeders, blow tanks, pneumatic valves, pipeline sections, and the baghouse filter at the receiving end. Fly ash is first collected from electrostatic precipitators and bag filters located near the boilers. It is then fed into the blow tanks via rotary airlock feeders that ensure a consistent material flow. The blow tanks are pressurized, and the material is discharged into the conveying pipeline in intermittent slugs. The dense-phase principle allows a high solids loading, reducing air consumption and wear. The fly ash pneumatic conveying system is designed to handle the fine, abrasive, and hygroscopic nature of fly ash. Special attention was paid to prevent moisture ingress, which could cause caking in the pipeline. The system includes air dryers and moisture traps to maintain the quality of the conveyed material. This pipeline pneumatic conveying solution has significantly improved the working environment at the Lille plant by eliminating dust emissions and reducing manual handling.
Since the commissioning of the headpowder system, the Lille power plant has experienced a 30% reduction in maintenance costs compared to the previous mechanical conveyor system. The enclosed nature of the pipeline pneumatic conveying minimizes dust escape, meeting stringent French environmental regulations. The system's energy consumption is 15% lower than typical dilute-phase pneumatic conveying systems, thanks to the optimized dense-phase technology. The plant operators report that the system operates quietly and requires only periodic inspection of valves and pipeline elbows. The pneumatic conveying case in Lille has become a benchmark for other thermal power plants in Europe. The success of this project is attributed to headpowder's extensive experience in France pneumatic conveying and its ability to customize solutions for local conditions. The company's engineering team provided on-site supervision during installation and commissioning, ensuring that the system met all performance specifications. The Lille pneumatic conveying project demonstrates that fly ash pneumatic conveying can be both economical and environmentally friendly for large-scale power generation facilities.
