An ash-disposal system with submerged scraper.

摘要

Apparatus for handling ash and slag produced in the combustion of coal or other ash-bearing fuel in the furnace (10) of a steam generator, including an ash hopper (14) beneath the furnace into which the ash initially falls. A pair of scraper conveyors (30, 32) which are submerged in water are located below the ash hopper (14) from which the ash is continuously disposed of. Water nozzles (40) are located in the ash hopper (14) for cooling and moving the ash.
