This invention discloses a circulating fluidized bed solid circulation rate adjustment system based on average particle size, comprising a solid circulation rate measuring device, a solid particle size measuring device, a storage device, and an adjustment device. Specifically, the solid circulation rate measuring device measures the specific value of the solid circulation rate during circulating fluidized bed operation; the solid particle size measuring device measures the resistance of the compacted solid particles inside the metal tube, compares it with the resistance characteristic curve of the solid particles, and analyzes to obtain the average particle size; the measured solid circulation rate is compared, and if it is within the required operating range, no adjustment is made; if the solid circulation rate is outside the required operating range, the adjustment device controls the discharge rate of the quartz sand bin to change the particle size of the solid particles in the circulating fluidized bed, thereby adjusting the solid circulation rate and realizing the control of the load change of the circulating fluidized bed boiler. This system efficiently and directly solves the problem of solid circulation rate adjustment in circulating fluidized beds, with fast response and excellent effect.
