    摘要： The present invention relates to a fluidized-bed classification method applicable to a fluidized-bed furnace system which requires to draw out incombustibles together with a fluidized medium in a fluidized bed furnace for combusting wastes such as municipal wastes, refuse derived fuel (RDF), waste plastics, waste FRP, biomass waste, automotive waste and waste oil, or solid combustibles such as solid fuel containing incombustibles like coal. The fluidized-bed classification method includes supplying a mixture (A) into a coarse classification section (1) partitioned by a partition wall (3) from a fine classification section (2); removing a foreign matter (L) having a relatively large size and a foreign matter (H) having a large specific gravity in the coarse classification section (1) while supplying fluidizing air to the coarse classification section (1); introducing the mixture from which the foreign matter (L, H) has been removed into the fine classification section (2) by mainly passing the mixture over the partition wall (3); and further removing the foreign matter (S) in the fine classification section (2) while supplying fluidizing air to the fine classification section (2).

    摘要翻译： 本发明涉及适用于流化床炉系统的流化床分级方法，该流化床分级方法需要在用于燃烧废物如城市废物，垃圾衍生燃料（RDF）等的流化床炉中与流化介质一起排出不可燃物。 废塑料，废玻璃钢，生物质废物，汽车废物和废油，或固体可燃物，如含有不可燃物如煤的固体燃料。 流化床分级方法包括：将混合物（A）从细分级部分（2）供应到由分隔壁（3）分隔的粗分级部分（1）中; 一边向粗分级部（1）供给流化空气，一边在粗分级部（1）中除去比重大的异物（L）和比重大的异物（H）。 通过主要使混合物通过分隔壁（3），将已除去异物（L，H）的混合物引入到细分级分区（2）中; 并且一边向微细分级部（2）供给流动空气一边进一步除去微细分级部（2）内的异物（S）。
