A wet ash remover installation includes a first wet ash remover (5) which is placed in operating position under an ash funnel (2) of a boiler and a second, similar, movable wet ash remover (12) placed in reserve position. The wet ash removers (5, 12) respectively consist of a water-filled trough (7) which houses a conveying implement and in which a dip member (4) connected to the ash funnel (2) is immersed. Each trough (7) is provided in one of the side walls (13) and at the same height with an opening (14) extending to the upper edge of the side wall (13) and having a width which corresponds to at least the width of the dip member (4) and a height which corresponds to at least the maximum depth of immersion of the dip member (4) into the wet ash remover (5). The opening (14) is surrounded by a frame (17) supporting a compressible seal (19) and is closed by a rotatable gate (16) which engages the opening (14) from the inside. The openings (14) are positioned in the respectively opposing side walls (13) of the wet ash removers (5, 12) and the wet ash removers (5, 12) are provided with coupling elements.

A chain conveyor in which two chains are connected together by scrapers and circulate in a casing, which are guided around rollers. In the direction of movement of the chain, in front of and above the entry of the chain into a roller, a shaped component is provided. The latter penetrates into the roller over a portion of the roller circumference. On its side remote from the roller, the shaped component is equipped with a deflector surface pointing towards the interior of the casing, the front edge of which surface is aligned with the shaped component.
