The invention discloses a coal-fired power plant turbulent burner suitable for low-order mixed coal combustion. The coal-fired power plant turbulent burner comprises a cone, an inner primary air shell, an inner secondary air shell, an outer primary air shell, an outer secondary air shell and a surrounding air shell, wherein the center cone is sleeved with the inner primary air shell, the inner primary air shell is sleeved with the inner secondary air shell, the inner secondary air shell is sleeved with the outer primary air shell, the outer primary air shell is sleeved with the outer secondary air shell, and the surrounding air shell is arranged on the outer side of the outer secondary air shell. An inner primary air channel is defined by the inner primary air shell, an inner secondary air channel is defined by the inner secondary air shell and the inner primary air shell, an outer primary air channel is defined by the inner secondary air shell and the outer primary air shell, an outer secondary air channel is defined by the outer primary air shell and the outer secondary air shell, and a surrounding air channel is formed outside the turbulent burner. By the adoption of the coal-fired power plant turbulent burner, the problem that air is insufficient when different types of coal of the large combustion difficulty characteristic difference are mixed and burned at a single primary air nozzle of a traditional turbulent burner is solved, and ignition and combustion of the types of coal difficult to burn can be promoted.
