40 CFR 63.861 - Definitions.
Lime kiln means the combustion unit (e.g., rotary lime kiln or fluidized-bed calciner) used at a kraft or soda pulp mill to calcine lime mud, which consists primarily of calcium carbonate, into quicklime, which is calcium oxide (CaO). Lime production rate means the rate at which dry lime, measured as CaO, is produced in the lime kiln.
