ABSTRACT:
An immersion plate fastened to the ash funnel of a steam generator combustion chamber and protruding into the water surface of a trough of a wet-ash remover filled with quenching water and located underneath the ash funnel. Carriers pass transversely through the immersion piece and are suspended by screws from the tubing of the funnel; a seal which is deformable in the direction of action of the screws is located between the immersion piece and the ash funnel. The cooled carriers may consist of two U-profiles welded together and the carrier ends outside the immersion pieces may be open. A U-shaped profile with the opening upwards is mounted on part of the carrier lying within the immersion piece. The sidewalls of the immersion piece may consist of several plate sections and each plate section has, at one edge, a slot for the edge of the adjacent plate, with play in the longitudinal direction. The screws are suspended pendulum-like from the ash funnel and the screw shanks pass through enlarged bores in the carrier; skirt-shaped support washers are located between the carrier and the nuts on the screws.
