The invention provides a turbulent burner manufactured by a magnesium alloy, and belongs to the technical field of gas devices. The turbulent burner comprises an outer burner, an inner burner, a pipe module, ignition columns and support columns, wherein the outer burner is annular, and is buckled with an outer fire cover; the outer fire cover and the outer burner form an outer mixing cavity; the inner burner is inserted in the middle part of the outer burner, and is buckled with an inner fire cover; the inner fire cover and the inner burner form an inner mixing cavity; a through hole communicating with the inner mixing cavity is formed in the bottom of the inner burner; multiple arc channels communicating with the outer mixing cavity are arranged around the through hole; the pipe module is provided with a secondary intake pipe corresponding to the through hole, and multiple main intake pipes corresponding to all the arc channels one to one; the ignition columns communicate with the pipe module, and vertically upwards extend to approach the outer peripheral side wall of the inner burner; and the support columns are vertically mounted below the pipe module. The turbulent burner has the advantage of good combustion effect.
