Lime reburning valmet

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 1250 tpd
