Dry ash handling system for power plants Journal Article

Abstract. The most commonly used wet ash handling system in which slurried ash is pumped to ash lagoons is compared with a relatively new dry ash handling system in which moistened fly ash and dewatered bottom ash are continously transported to the disposal area and compacted. The proposed system for a typical 2,000 MW power plant features submerged drag bar conveyors under the boiler
