    摘要： A scrubber tray for a wet scrubber tower of a flue gas purification device includes a multiplicity of spindles, arranged across an inner horizontal cross section of the wet scrubber tower. Adjacent spindles are arranged at a horizontal distance to each other. At least some of the spindles are pivot-mounted to allow a rotative movement around a corresponding spindle axis and to arrange the respective spindle at a predetermined rotation angle. At least some of the spindles are equipped each with at least one protrusion, which extends outwardly from the respective spindle. The spindles and protrusions are shaped and arranged to provide flow-through openings between adjacent spindles and protrusions respectively. Each flow-through opening defines a corresponding flow-through area, and they add up to 10%-80% of the inner horizontal cross section of the associated scrubber tower, independently of the respective rotation angles of the spindles.

    摘要： A fluidized bed heat exchanger with a chamber (24) comprises a solid particles inlet port (22), a solid particles outlet port (30), arranged at a distance to the inlet port (22), means (46) for introducing a fluidizing gas from a bottom area into the chamber (24). The heat exchanger further comprises at least two heat transfer means (28) within the one chamber (24), each being provided with a heat transfer medium inlet port (42) and a heat transfer medium outlet port (44), wherein a first heat transfer means (28) is designed as a reheater and second heat transfer means (28) is designed as a superheater to achieve a heat transfer medium temperature and a heat transfer medium pressure above that of the reheater. At least one of the reheater or superheater is made of a multiplicity of heat transfer tubes arranged in a meandering fashion for conveying a heat transfer medium.
