A pulverized coal concentrator with inner and outer concentration capable of being adjusted in real time is arranged at an outlet section of a primary air flue of a combustor and mainly comprises an adjustable pulverized coal baffle mechanism and an adjustable primary air flue partition plate. The adjustable pulverized coal baffle mechanism is arranged at the upstream part of the outlet section of the primary air flue of the combustor and comprises a plurality of sets of concentration baffle combinations arranged in the circumferential direction. Each concentration baffle combination is composed of a baffle fixing support, a rotary anti-abrasion baffle, a two-link rod, a sliding lantern ring and an adjusting pull rod, wherein the rotating angle of the baffle can be adjusted through the axial movement of the adjusting pull rod so that the movement direction of pulverized coal airflow after the pulverized coal airflow passes through concentration baffles can be changed, and the radial concentration difference of the pulverized coal airflow in the primary air flue is achieved. The adjustable primary air flue partition plate is arranged at the downstream part of the outlet section of the primary air flue of the combustor and comprises a fixed partition plate body, an adjustable partition plate body and a partition plate adjusting pull rod, wherein the length of the coinciding part of the adjustable partition plate body and the fixed partition plate body can be adjusted through the axial movement of the partition plate adjusting pull rod, the maintaining position of the radial pulverized coal concentration difference of the primary air flue after concentration of the pulverized coal is changed, and the adjustment of the pulverized coal concentration effect at an outlet of the combustor is achieved.
