The rotary kiln is 60 m long and 3 m in diameter. It rotates at 1 rpm. Coal is ground to a fine powder, mixed with air and blown into the rotary kiln, where it ignites, producing the necessary heat. Theoretically, to convert 1 tonne of limestone into lime, 3.17 GJ of heat energy is required, as the chemical reaction occurring is endothermic.
