PURPOSE:To be able to make fluidization satisfactory and also burning gentle and stable by switching the velocity of fluidizing air spouted from distributing pipes in high and low speed alternatively for each pipe when materials to be burnt are transferred, crushed, and thrown on air distributing pipes. CONSTITUTION:After materials to be burnt are transferred by a feeder 5 and crushed by a crusher 10 placed at the discharge hole 9 of the feeder, the materials are supplied on air distributing pipes 2 through an input hole 4 and fluid medium 11 such as sand etc. is supplied from a circulation line 20. Fluidizing air flowing from an air supply pipe 13 for fluidization is spouted from the pipe 2 and fluidizes the materials 3 and the medium 11 to form a fluidized layer 14. As the materials to be burnt are disassembled properly, their fluidized condition is made satisfactory. As fluidizing air velocity is changed in high and low speed for each air distributing pipe 2 and is also switched alternatively and continuously, the materials are stirred uniformly and are able to be burnt gently as a whole.
