Fine slag (FS) is an unavoidable by-product of coal gasification. FS, which is a simple heap of solid waste left in the open air, easily causes environmental pollution and has a low resource utilization rate, thereby restricting the development of energy-saving coal gasification technologies. The multiscale analysis of FS performed in this study …

Bottom ash and boiler slag are both well-draining materials that can be dewatered in 1 or 2 days. Ponded ash, which typically contains fly ash, requires a longer time to dewater, up to two weeks. The higher the percentage of fly ash in ponded ash, the longer the dewatering time. Crushing or Screening.
