A stepwise gas distribution and graded oxygen supplementation device for distribution of high-ratio circulating flue gas is provided. The circulating flue gas distribution main pipe includes stepped sections communicated with each other in sequence, and pipe diameters of the stepped sections are reduced in sequence along a flue gas moving direction. The circulating flue gas distribution branch pipes are each in communication with and arranged at one side of the corresponding stepped section. The flue gas sealing cover is in communication with gas outlet ends of the circulating flue gas distribution branch pipes. The oxygen supplementing devices are arranged in the circulating flue gas distribution branch pipes needing to increase oxygen content. The oxygen supply device is in communication with gas inlet ends of the oxygen supplementing devices.
