Characterization of the material and unit operations

A lime kiln is around 70-100 meters long and around 2-4 meters in diameter. The kiln is typically equipped with product coolers at the discharge end where hot reburned lime meets incoming secondary air in a counter-current heat-exchange process. Dusting in a lime kiln occurs when fine material chaotically swirls at the discharge end of the kiln.

The lime kiln in a kraft pulp mill converts lime mud, which is largely composed of calcium carbonate (CaCO 3), into burnt lime, i.e., calcium oxide (CaO), and carbon dioxide (CO 2). This thermal decomposition reaction requires a high temperature and occurs spontaneously when the lime mud temperature exceeds approximately 800 °C in a gas
