The utility model provides a circulating fluidized bed boiler, which belongs to the technical field of boilers and comprises a separator, a heat absorption structure and a dust removal structure. A hot air transmission channel is arranged at the top end of the separator. One end of the heat exchanger is connected to the hot air conveying channel, the other end of the heat exchanger is connected to the water tank, and the guiding assembly is arranged at the steam inlet. The dust remover is connected with the hot air conveying channel, one side of the collecting box is connected with the steam outlet, the other side of the collecting box is connected with the collecting cover through the fly ash conveying channel, and the opening direction of the collecting cover faces the first ash outlet. Through the arrangement of the structure, the problems that in the operation process of an existing circulating fluidized bed boiler, due to the fact that water vapor enters the water tank through the heat exchanger, a large
