| description | The invention provides a high-efficiency ignition burner of a dry pulverized coal fluidized-bed gasifier. The high-efficiency ignition burner comprises an inner burner, an outer burner and an outer-layer cooling water jacket, wherein the front end of the outer burner is a sealed end and comprises an outer wall, a first middle layer, a second middle layer, a third middle layer and an inner wall from outside to inside. An annular secondary oxygen inlet channel is arranged between the outer wall and the first middle layer. Secondary oxygen outlets are all distributed at the top of the channel and are inclined inward and axially extended to the front end of the outer burner. An inner-layer cooling water jacket includes an inner-layer cooling water effluent annular channel, an inner-layer cooling water inflow annular channel and an inner-layer cooling inflow and effluent communication part. The inner-layer cooling water effluent annular channel is arranged between the first middle layer and the second middle layer |
