The "Pneumatic Conveying of Fly Ash at Tacna Power Plant in Peru" represents a benchmark pneumatic conveying case in Latin America. This project successfully applied positive pressure pneumatic conveying technology to transfer fly ash from electrostatic precipitators to a central storage silo. The power plant, located in the Tacna region of southern Peru, faced strict environmental regulations requiring a sealed and dust-free handling method. Headpowder provided an engineered system that meets all performance and safety standards.
Tacna is characterized by an arid desert climate with high solar radiation and large temperature swings, which posed unique engineering challenges. The fly ash generated by the coal-fired boilers is fine, abrasive, and potentially hazardous if released into the atmosphere. Traditional mechanical conveyors were unsuitable due to dust leakage and high maintenance. Therefore, a pneumatic conveying case with dense-phase positive pressure conveying was chosen, ensuring gentle transport at low velocity with minimal equipment wear.
The system includes a pressure vessel, a rotary feeder, a wear-resistant pipeline, and a PLC-based control panel. Fly ash enters the pressure vessel from the dust collector hoppers. Compressed air is injected into the vessel to fluidize the powder and push it through the pipeline toward the silo. The conveying pressure is maintained at 0.2 to 0.3 MPa, while the flow velocity is controlled below 8 m/s to protect the pipe from erosion.
This positive pressure pneumatic conveying system offers several major benefits. Fully sealed operation prevents dust emission and keeps the plant environment clean. The low-velocity dense-phase flow reduces energy consumption and pipeline wear, resulting in lower operating costs. Additionally, the automated control system allows continuous monitoring of pressure and flow, quickly detecting any blockage. The design also prevents moisture ingress, preserving the quality of fly ash for downstream applications such as cement production.
The project was engineered and supplied by Shandong Headpowder Engineering Co., Ltd., abbreviated as headpowder. The company, headquartered in Shandong, China, is a specialist in pneumatic conveying systems for bulk materials. With extensive experience in Latin American pneumatic conveying projects, headpowder offers services from design to commissioning. For this Tacna project, the assigned contact is Manager Zhang, who managed all client communications and technical coordination.


Interested parties can contact Manager Zhang via WeChat at 15662777102. The company address is in Shandong, China. The Tacna power plant system has a conveying capacity of 15 tons per hour over a distance of 350 meters, with a vertical lift of 40 meters. The pipeline is made of wear-resistant steel with an eight-millimeter wall thickness, giving it an expected service life of over ten years. This robust design ensures reliable operation under continuous duty.
Headpowder's scope of work included installation supervision, commissioning, and operator training. During commissioning, the system parameters were precisely tuned to match the actual fly ash characteristics. The plant staff received comprehensive training on system operation and routine maintenance. The successful handover was followed by a warranty period, during which headpowder provided remote troubleshooting support. This comprehensive approach reduced startup risks and ensured long-term system reliability.
In summary, this pneumatic conveying case demonstrates the proven capability of positive pressure conveying in Latin American power plants. The Tacna project is a model for efficient, safe, and environmentally sound fly ash handling. Headpowder continues to provide advanced solutions and responsive support.
