Abstract (en)
1. Device for the production of a homogeneously distributed and directed flow of flue gas following a flow deflection and for the flue dust separation in a multiple draw tank, in which a cascade with two or more shovels (S1, S2, ..., Sn) in the deflection (U) of the vertical flue draw (30) is built in, after which a heat exchanger is located in the ascending current, characterized in that the shovels (S1, S2, ..., Sn) of the cascade are located in the transition region of the ascending draw (A) and level with straight profile and for the flow of flue gas particles with an angle of incidence smaller than or equal to 90 degrees and a slope angle smaller than or equal to 45 degrees.

Die Einrichtung zur Verbesserung der Strömungsumlenkung von Rauchgas und der Flugascheabscheidung in einem Mohrzugkessel weist ein n-schaufeliges Schaufelgitter (S1/S2/.../Sn) in der Umlenkung (U) des Vertikalzuges (30). Die Schaufeln (S1,S2...,Sn) des Schaufelgitters (S1/S2/.../Sn) in der Umlenkung (U) des Vertikalzuges (30) sind vorzugsweise im Übergangsbereich des Aufwärtszuges (A) angeordnet und das Schaufelgitter (S1/S2/.../Sn) besteht aus ebenen Schaufeln (S1,S2...,Sn).
