description The utility model discloses a high-efficiency pulverized coal burner of a gasification furnace of a dry pulverized coal fluidized bed. The high-efficiency pulverized coal burner comprises a pulverized coal annular channel, a pulverized coal swirler which is arranged in the channel, a center channel and an oxygen swirler arranged at the front end of the center channel; the cavities in the front end of the pulverized coal annular channel and the front end of the central channel adopt necking structures; dry pulverized coal and oxygen are respectively swirled and accelerated in a conveying process, so that the dry pulverized coal and the oxygen are fully mixed and contacted within a short time and a short distance in a swirling way; therefore, the combustion is facilitated and is uniform; in addition, the burner is worn slightly, and the service life of the burner is long.
