Lime Production: Industry Profile

2015-9-1  Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime CaCO 3 MgCO 3 + heat

2015-9-10  Another alternative process that is beginning to emerge in the United States is the parallel flowregenerative (PR) lime kiln. This process combines 2 advantages. First, optimum heating conditions for limecalcining are achieved by concurrent flow of the charge material and combustion gases. Second, the multiple-chamber regenerative process uses the charge material as the heat transfer medium to preheat the combustionair. The basic PR system has 2 shafts, but 3 shaft systems are used
