Ash materials handling system FLUIMAC®

Due to the major advantages over PC boilers, the use of FBC boilers has grown rapidly as well as their capacity. This required not only boiler technology but also auxiliary system improvements. One of the critical auxiliary systems of FBC boilers is the bed ash extraction system, which must be capable of removing and cooling hot and abrasive materials of different sizes. Based on its field-proven MAC® technology for PC boilers, Magaldi has developed the FLUIMAC® system. Unlike conventional bed ash extraction systems, responsible for huge water consumption, high maintenance costs, environmental issues, and negative effects on boiler operation, the FLUIMAC® dry system delivers a reliable, cost-effective, and environmentally friendly operation thanks to the unique combination of the dry cooling process and the dependable Superbelt® conveyor. The use of the dry bed ash handling system results in significant water and O&M cost savings. Since no water is used for ash cooling and conveying, water circulation and treatment systems are no longer necessary, and the associated costs are eliminated. The absence of water also cuts maintenance costs arising from corrosion and jamming along the sluicing line and creates a cleaner and safer work environment.
