The utility model discloses a compact two-order one-inlet and five-outlet pulverized coal equalization device which is arranged in the vertical direction and provided with one inlet and five outlets. The pulverized coal inlet is formed in the bottom of the equalization device, and the connecting line of the centers of the outlets is in the same straight line or approximately in the same line. The compact two-order one-inlet and five-outlet pulverized coal equalization device comprises an inlet rectangular reducer pipe, a first-order flow equalizing grid, a first-order equalizing grid, a first-order equalizing shell, a second-order flow equalizing grid, a second-order equalizing shell, a left-side second-order equalizing grid, a right-side second-order equalizing grid and equalizing rectangular outlet tubes. The inlet rectangular reducer pipe is connected with the first-order equalizing shell internally provided with the first-order flow equalizing grid and the first-order equalizing grid, the first-order equalizing shell is connected with the second-order equalizing shell, and the second-order equalizing shell is connected with the equalizing rectangular outlet tubes. The compact two-order one-inlet and five-outlet pulverized coal equalization device has the advantages that airflow with pulverized coal at an outlet of a coal pulverizer is continuously and stably distributed to five combustors so that the amount of air flowing into a primary air pipeline, the amount of pulverized coal entering the primary air pipeline and the pulverized coal particle size distribution are the same, and the overall structure is compact.
