Abstract

Asche, die bei der Verbrennung von staubförmiger Kohle in einer Kohlenstaubfeuerung anfällt und nach dem Austrag aus der Kohlenstaubfeuerung in einem mit Wasser gefüllten Naßentascher (2) gekühlt wird, wird dadurch entwässert, daß die aus dem Naßentascher (2) ausgetragene Asche auf einen Schwingentwässerer (14) gegeben, dort von dem anhaftenden Wasser befreit und in einen transport- und weiterverarbeitungsfähigen Zustand überführt wird.
