Dry Ash Silo
The Ling Dry Ash Silo is tapered at the top and bottom, whereas conventional silos are tapered at the bottom only. The Ling spindle-shaped design allows for easy conveyor-connection and maximizes useful silo volume (relative to total volume). To extract ash from the silo as "swirling-scraper" system is used, which prevents jamming and has a long service life. The swirling scraper allows ash extraction to be easily controlled, and it provides a uniformly distributed flow of ash. Other ash silo extraction systems use rotating-impeller or flashboard-type extractors. The rotating-impeller occasionally jams and the flashboard-type is less-easily controlled.
The Ling Silo has a dust-proof crown (shaped like a wide-brimmed hat) that prevents fly-ash and solves the incurable environmental pollution problem.
