Summary:The utility model relates to a core tube of a combustion zone of a phosphorite powder pellet vertical kiln. The core tube comprises a pellet vertical kiln wall shell, a core tube (3) and a core tube fixing rack (4) and is characterized in that the core tube (3) is mounted at the center of a sintering zone part in a phosphorite powder pellet vertical kiln chamber through the fixing rack (4) on the pellet vertical kiln wall shell; the upper part of the core tube (3) is cylindrical, and the lower part of the core tube (3) is inverted-cone-shaped. According to the core tube, the problem of the existing phosphorite pellet sintering vertical kiln that material dropping is hindered due to the fact that pellets are bonded into large lumps after calcination and a whole calcination face can be bonded into a whole body in a serious case is solved; the sintering quality of the phosphorite powder pellets is guaranteed, and the production cost of phosphorus chemical enterprises is reduced.
