A deasher arrangement in which a water-filled trough is arranged beneath the ash hopper of a boiler. The trough is laterally movable, and accommodates a conveying device. A lifting device is provided with a lift corresponding at least to the boiler expansion. The trough is associated, furthermore, with a dipping element connected to the ash hopper and permanently extending into the water fill of the trough during operation of the boiler. The trough consists of two sections separated by a partition wall, and accommodates one conveying equipment each. The partition wall has a height which is lower than the side walls of the trough. The top of the partition wall is situated above the bottom of the dipping element when the boiler is in operation and the trough is raised. An additional partition wall may be provided with a collecting tray therebetween.
