Pneumatic Conveying of Waste Incineration Fly Ash in Jambi: A Case Study. Keywords: pneumatic conveying case, Southeast Asia pneumatic conveying, positive pressure pneumatic conveying.

This article presents a practical case study of waste incineration fly ash pneumatic conveying in Jambi, Indonesia, completed by Shandong Headpowder Engineering Co., Ltd. (Headpowder). The project focuses on the safe and efficient transfer of fly ash generated from municipal solid waste incineration. Positive pressure pneumatic conveying was selected as the core technology. This method is widely used in Southeast Asia because of its enclosed operation, flexible layout, reliable performance, and low environmental impact.

The material handled in this project is fly ash from a waste-to-energy plant. Fly ash has a very fine particle size, low bulk density, and a strong tendency to agglomerate. It also contains heavy metals and trace dioxins, which pose serious risks to human health and the environment. Therefore, the conveying system must be fully sealed to prevent any leakage. In Jambi, the tropical climate with high humidity further increases the risk of material sticking and clogging. Headpowder's engineering team carried out detailed material testing and system design to overcome these challenges, ensuring smooth and continuous operation.

The positive pressure pneumatic conveying system supplied by Headpowder uses compressed air as the driving force. The system consists of a pressure vessel (blow tank), a conveying pipeline, special discharging valves, an automatic control unit, and a bag filter for dust collection. The blow tank is charged with fly ash from the hopper, then pressurized with compressed air. When the pressure reaches the set value, the outlet valve opens and the material is conveyed through the pipeline to the destination silo. The conveying velocity and air flow are carefully calculated to avoid pipe wear and material degradation. For abrasive fly ash, the pipeline is designed with appropriate wall thickness and bend radius. The system operates in fully automatic mode, with PLC control and real-time monitoring. Such a design ensures continuous operation, which is essential for a waste incineration plant that runs 24/7.

One of the key considerations for this project was the local site conditions in Jambi. The conveying distance and elevation difference were fully considered during the design phase. The positive pressure system is particularly suitable for the long-distance and multi-point delivery requirements of this project. Compared to mechanical conveyors, pneumatic conveying has no rotating parts inside the pipe, which reduces maintenance costs. The sealed pipeline also prevents odor and dust emissions, creating a clean working environment. In addition, the system occupies a small space, making it easy to install in the existing plant layout. The power consumption is optimized by selecting a suitable compressor and controlling the solid-to-air ratio.
