A circulating fluidized bed for heat-treating solid waste such as of municipal waste and waste plastic. The circulating fluidized bed is of a loop type and is divided into fluidized beds (1, 2) partitioned at an intermediate portion by moving beds (9, 10) and having independent free boards (22, 25). In the circulating fluidized bed, a fluid medium is circulated by a driving force generated because of the difference in specific gravity between the moving beds (9, 10) and the fluidized beds (1, 2).
