Post How Can Improve Decomposition Rate of Rotary Kiln?
The decomposition rate of Aggregate Crushing Solution shows the decomposition degree of the
carbonate in the raw materials to see whether the equipment design of the
preheating and decomposition system is rational and whether the technical
parameters are suitable. The in-kiln decomposition rate is the main index of
measuring the normal operation of the decomposition furnace. High decomposition
rate means that the role of the decomposition rate has been fully played, for
this reason, it is necessary to properly improve the decomposition rate of the
rotary kiln. The following measures can be taken to realize the improvement of
in-kiln decomposition rate of rotary kiln.



(1) The volume design of the decomposition furnace should take into
consideration the flammability of the fuel and make sure that the materials have
sufficient staying time inside the furnace. Influenced by the grade and the
fineness of the coal powder, the staying time needed by the raw materials and
coal powder should be shorted, so is the space needed for independently burning
the coal powder.

(2) The volume design of the decomposition furnace should take into
consideration the decomposition speed of the raw materials which is not only
related to the property of the limestone, but related to the atmosphere inside
the decomposition furnace.

(3) When setting the position and number of the material and coal feeding
point, it is necessary to consider to reserve sufficient space for the
combustion of the fuel before the raw materials are fed into the furnace.
Especially for the anthracite that is not combustible, we should also consider
the position and direction of the tertiary air induced to make sure that the
coal powders are evenly and sufficiently burnt.
