Dry-pulverized-coal gasification combined burner

The invention discloses a dry-pulverized-coal gasification combined burner comprising a pulverized coal burner and an igniting burner. The pulverized coal burner sequentially comprises a first water-cooling jacket, a pulverized coal channel, a first oxidant channel and an inner barrel from outside to inside. The pulverized coal channel is directly adjacent to the first oxidant channel, and contracts toward the axial direction of the pulverized coal burner, at a position, adjacent to a flame-forward end. The first water-cooling jacket comprises a first water-inflowing channel, a window-type water-cooling groove and a first water-outflowing chanel, and the first water-inflowing channel is communicated with the first water-outflowing channel through the window-type water-cooling groove which is spirally wound at the flame-forward end of the pulverized coal burner. The igniting burner is arranged in the inner barrel and comprises a second water-cooling jacket, a second oxidant channel, a fuel channel, an igniter and a center nitrogen channel. By the arrangement, an ignition process is simplified, and reliability of ignition and operation of pulverized coal is improved; flame diameter is effectively controlled, a membrane water-cooling wall is prevented from being damaged by flames, and reliability of a gasification furnace is improved.
