Energy Efficient Lime Reburning
A lime kiln is used to convert calcium carbonate caco3 into burnt lime cao. the burned lime reacts with the green liquor and precipitates as caco3, thus creating a closed loop with the recausticizing. the valmet lime kiln is based on a long line of successful projects starting in taking the production from just 15 tpd to 1,250 tpd. flash.A lime kiln uses heat, motion, and airflow to convert lime mud to lime, or in chemical terms, calcium carbonate to calcium oxide. this process is referred to as calcining . the most common lime kiln designed found at kraft pulp mills is the rotary lime.
