    Jan 07, 2021 By heating stone or shells red hot, about 900 Celcius (called calcining), we can change lime from it’s stable inert form, calcium carbonate, into Calcium oxide. This reaction with water makes it into Calcium Hydroxide, which is similar to lye, but not as strong

    energy efficiency of the lime kiln. Hot lime drops through holes at the discharge end of the kiln, into the tube coolers where it preheats the combustion air to 260-370 C. The lime thereby leaves the kiln with a temperature of 200-300 C instead of ~1100 C, reducing the amount of energy that has to be provided to the process [5]
