Limestone Pneumatic Conveying Case at Bergen Power Plant

Keywords: Pneumatic Conveying Case, European Pneumatic Conveying, Bin Pump Pneumatic Conveying.

Bergen Power Plant, located in Norway, required a clean and reliable system to feed limestone powder into its flue gas desulfurization process. The plant selected a bin pump pneumatic conveying system supplied by Shandong Headpowder Engineering Co., Ltd., also known as headpowder. This project is an important European pneumatic conveying case and a successful reference for limestone powder handling in the power industry.

Limestone powder is abrasive and can become sticky when moisture is present. Mechanical conveyors have many moving parts, need frequent maintenance, and may create dust. Dilute-phase pneumatic conveying can cause wear and powder degradation because of high velocity. headpowder solved these problems with a dense-phase bin pump system that operates at lower velocity and higher solids-to-air ratio. The selected solution ensures stable feeding and low maintenance over the life of the equipment.

The bin pump is the core equipment in this European pneumatic conveying project. It is a pressure vessel designed for batch operation. In each cycle, the inlet valve opens and limestone powder enters the pump by gravity. Then the valve closes and compressed air pressurizes the vessel, fluidizing the powder and pushing it through the conveying pipeline. When line pressure drops, the conveying cycle ends and the pump is vented for the next batch. The PLC repeats this sequence automatically. A compressor with an air receiver provides stable conveying air for every cycle.

The system includes the silo discharge device, butterfly valves, the bin pump vessel, a compressor or Roots blower, air receiver, pipeline boosters, wear-resistant bends, target boxes, and a receiving bin. Pressure transmitters, level switches, and valve position sensors provide real-time feedback. The system can be operated locally or from the power plant control room.

Dense-phase conveying gives several benefits. Low velocity reduces pipe wear, which is especially important for limestone powder. The enclosed pipeline prevents dust leakage and keeps the working environment clean. The system has few rotating parts, so reliability is high. Energy consumption is lower than in dilute-phase conveying because the material moves as concentrated plugs. It can also convey over long distances with little height loss. This design reduces material degradation and dust generation.

As a European pneumatic conveying case, the Bergen project required strict safety and environmental compliance. headpowder included proper grounding, explosion precautions, dust-tight flanges, and pressure relief protection. The control system followed electrical standards commonly used in Norway and the European Union. Installation and commissioning were planned to minimize downtime.

After commissioning, the limestone feeding process at Bergen Power Plant became stable and economical. The bin pump system has operated with very few failures. Maintenance time is reduced because pipe wear is small and valve components are easy to inspect. The working environment around the conveying line is no longer dusty. The plant has also reduced the loss of limestone powder caused by spillage and leakage. As a result, the total operating cost of flue gas desulfurization has decreased.
