Kiln operation produces partial fire kiln ventilation fundamental reason is uneven, well-ventilated part of the fuel burning speed, bottom fire position on the move,

and the temperature is high, poorly ventilated areas fuel combustion is slow, not even when serious combustion, so the end of the fire along with the downward

movement of materials and sink, forming part of the bottom of the fire position is inconsistent, which led to such a partial fire There are several reasons: one, with a

large cooling, so that the kiln ventilation is uneven, sometimes large cooling zone exists, often associated with the material related to improper operation. 2, due to

blending uneven, so that the local temperature rises more than coal, or raw ingredients uneven, resulting in large kiln knot, refining side seriously, these parts of the

ventilation resistance, local ventilation formation of partial fire. 3, so that the local coal blending less uneven temperature is low, or uneven raw ingredients, easy to

burn the material is poor, due to poor dissemination of sintered material, the material gap between the small, local exhaust ventilation formation of partial

resistance of large fire. 4, feeding unloading operation is not correct, balanced feeding doesn Key kiln feeding resistance, or the end of the fire on the rise in the

kiln error of judgment at the judgment of the ventilation is poor ventilation, or take measures contrary, the result is exacerbated by the kiln ventilation

inhomogeneity. 5, the device causing the fire side, usually at a fixed location, such as the center of the kiln feed dustpan centerline do not coincide, and the kiln or

kiln body different heart, so that when feeding the same circular path, not evenly distributed in the kiln, the relative kiln wall for easy normal binder uneven. The
