Background
During lime calcination, the raw material stoneThe effect of the apatite particle size is very large. Due to CO2Since the separation of (2) is gradually progressed from the surface of the limestone toward the inside, the calcination of the limestone having a large particle size is more difficult than that of the limestone having a small particle size, and the time required therefor is also long. CO release from large particle size limestone2Since gas is discharged from the inside of the crystal lattice, high temperature is required to generate high CO2And (4) pressure. In fact, it is very difficult to calcine limestone with a particle size of more than 150mm, and such high-temperature calcination (1250 to 1350 ℃) causes excessive burning on the surface of the limestone, shrinkage, cracking, and impurities (SiO)2、Al2O3Etc.) also cause slagging phenomena when present. If CO is present2The separation is incomplete, and the raw ash with large burning proportion is formed. The same happens when limestone with a wide range of particle sizes is calcined, i.e. if standard small particle size limestone is calcined, the larger particle size is more green burnt, whereas if large particle size calcination is aimed, the smaller particle size is over burnt, the calcination time at a certain temperature is proportional to the square of the thickness of the lime, 80mm blocks require 4 times the calcination time of the latter compared to 40mm blocks.
