Zusammenfassung:The invention discloses a desulfurization system of a circulating fluidized bed boiler. The desulfurization system comprises a cyclone separator (12), wherein the upper part of the cyclone separator (12) is connected with the upper part of a hearth (11) of the boiler; the lower part of the cyclone separator (12) is connected with the lower part of the hearth (11) through a material returning pipe (13); the material returning pipe (13) is provided with a desulfurization agent inlet (10); and the desulfurization agent inlet (10) is formed in a negative-pressure position of the material returning pipe (13). The desulfurization agent in the desulfurization system can be easily sprayed into the boiler, the desulfurization efficiency is high and the energy consumption is low.
