Abstract

Eine Naßentascheranlage enthält einen ersten, in Betriebsstellung unterhalb eines Aschetrichters (2) eines Kessels befindlichen Naßentascher (5) und einen zweiten, gleichartigen, in Reservestellung befindlichen, verfahrbaren Naßentascher (12). Die Naßentascher (5, 12) bestehen jeweils aus einem mit Wasser gefüllten und ein Förderorgan aufnehmenden Trog (7), in den ein mit dem Aschetrichter (2) verbundenes Eintauchstück (4) hineintaucht. Jeder Trog (7) ist in einer der Seitenwände (13) in gleicher Höhe mit einer bis zur Oberkante der Seitenwand (13) reichenden Öffnung (14) versehen, deren Breite mindestens der Breite des Eintauchstückes (4) und deren Höhe mindestens der maximalen Eintauchtiefe des Eintauchstückes (4) in den Naßentascher (5) entspricht. Die Öffnung (14) ist von einem eine zusammendrückbare Dichtung (19) aufnehmenden Rahmen (17) umgeben und durch eine schwenkbare Klappe (16) verschließbar, die sich von innen an die Öffnung (14) anlegt. Die Öffnungen (14) sind in den einander zugewandten Seitenwänden (13) der Naßentascher (5, 12) angeordnet, und die Naßentascher (5, 12) sind mit Kopplungselementen versehen.

Figure 00000001
A wet pocket machine contains a first wet pocket machine (5), which is in the operating position below an ash funnel (2) of a boiler, and a second, similar, movable wet pocket machine (12) which is in the reserve position. The wet ashtrays (5, 12) each consist of a trough (7) filled with water and receiving a conveying element, into which a plunge piece (4) connected to the ash funnel (2) is immersed. Each trough (7) is provided in one of the side walls (13) at the same height with an opening (14) reaching to the upper edge of the side wall (13), the width of which is at least the width of the immersion piece (4) and the height of which is at least the maximum immersion depth of the immersion piece (4) in the wet bag (5). The opening (14) is surrounded by a frame (17) which holds a compressible seal (19) and can be closed by a pivotable flap (16) which bears against the opening (14) from the inside. The openings (14) are arranged in the mutually facing side walls (13) of the wet handler (5, 12), and the wet handler (5, 12) are provided with coupling elements.
