Kinetics study of the finely dispersed limestone thermal decomposition reaction
Termogravimetric studies on four various fractions diameters particles of calcium carbonate used in the industrial cyclone-calciner furnace for manufacturing of lime were carried out based on linear increase of the temperature. The values of activation energy E, preexponential factor A in Arrhenius equation, as well as the mechanism of the particles thermal decomposition reaction were defined. The work results provide important data to further study the efficiency of the limestone thermal decomposition chemical reactions and optimizing furnace design and operation modes.
