COATING INHIBITOR FOR LIME CALCINATION APPARATUS AND METHOD FOR THE INHIBITION OF COATING

摘要

A coating inhibitor containing a magnesium compound having particle sizes of 0.1 to 30µm. The magnesium compound is magnesium hydroxide, magnesium carbonate, magnesium oxide, or the like. The magnesium compound is in a state dispersed, suspended, or dissolved in water or oil. The method for inhibiting the coating in a lime calcination apparatus comprises operating a lime calcination apparatus while introducing the coating inhibitor into a calcination kiln intermittently. The coating inhibitor is uniformly introduced into the kiln within the range of 10 to 60min/day in an amount in terms of MgO of 0.1 to 10kg per over-dry ton of the lime raw material to be treated.
