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 1904 taking the production from just 15 tpd to 1,250 tpd. Flash Dryer
