Ash Handling System: Boilers burning pulverized coal (PC) have bottom furnaces. The large ash particles are collected under the furnace in a water-filled ash hopper, Fly ash is collected in dust collectors with either an electrostatic precipitator or a baghouse. A PC boiler generates approximately 80% fly ash and 20% bottom ash. Ash must be collected and transported from various points of the

Your material-handling system is equipped with filters at two locations: one in the dust collector near the vacuum pump and the others in each vacuum receiver. A blinded filter has the same effect as too many elbows in a system design: Backpressure builds and your system loses conveying capacity. As the filters clog, you'll notice that it takes longer and longer to fill a vacuum receiver or

Unit loads are designed to be as large as the material handling system can practically manage, subject to obvious conditions—such as safety, convenience and access. KEYPOINT The factors that can influence the design of the material handling system are: the characteristics of the material to be handled; issues of flow rate, routing, and scheduling; considerations arising from the plant layout

Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse. Pressurized pneumatic ash conveying may also be
