Ash Disposal System. The function of the Ash Disposal System is to dispose of bottom ash, economizer ash, and pyrites produced in the operation of the plants. This system is composed of hoppers, storage tanks, clinker grinders, ash conveying pumps, conveying lines, water supply lines, pond return lines, and ash ponds. Economizer ash is conveyed pneumatically from the economizer hoppers to the pyrites and economizer storage tank. The pyrites, which are rejected by the coal pulverizers, are also sluiced to this storage tank. The storage tank is emptied periodically by sluicing the contents to the ash pond. Ash and clinkers falling into the bottom ash xxxxxx are put through the clinker grinder and sluiced to the ash pond.
Ash Disposal System. The fly ash slurry disposal system serves to dredge and pump fly ash slurry from the fly ash slurry disposal pond, mentioned above, to the evaporation pond and return reclaimed water to the fly ash slurry pond. The system includes a barge mounted dredge, booster pumps, a 16" diameter slurry pipeline, evaporation pond, a barge mounted return line pump, emergency drain pumps, sump pumps, seal water pumps, all electrical services, valves, miscellaneous piping, and all other necessary equipment. Facilities are included for bottom ash disposal.
Ash Disposal System. This System, which transports fly ash from the precipitation hoppers to the fly ash storage silos, includes several pneumatic conveyors and associated blowers, filters and pipelines for transporting ash to the ash storage silos, two ash storage silos and associated steel support structures, stairs and platforms, and eight dustless unloaders.
Ash Disposal System. The ash disposal system utilizes a hydraulic analysis based on the following: Material : BBA Pressure gradient frictional head loss : 0.281 kPa/m @ Cw = 30% Concentration by mass, Cw : 20% – Capacity. : 30% – Power.
