Kiln Performance & Efficiency Formulas ( updated and Completed )
Volumetric loading of Kiln
Thermal loading of Kiln
Specific thermal loading for precalciner kilns of modern design : 4.0 to 5.0 M kcal/hr/m2
Feed moisture evaporation rate
Evaporation ratio of kiln volatile cycle
K, Na, S & Cl are all subject to partial evaporation at kiln burning zone temperatures.
Volatization in burning zone and condensation in preheater may be represented as shown below. The external cycles through dust collector are not considered; if dust is not wasted, then virtually all “e” is returned to the kiln.
