METHOD OF CALCINING LIMESTONE - BUTLER W,CA

This invention relates to a method for calcining limestone to produce lime. Calcination of limestone is the conversion of limestone Ca CO 3 into lime CaO by heating the limestone to a temperature of at least 1600° F to disassociate the CO 2 therefrom, leaving the desired CaO. Known methods for calcining limestone for the most part are based on the use of either vertical kilns, horizontal ...

Calcination - Burning Limestone Unity Lime

Heat transfer for lime burning can be divided into three main stages: ‘Preheating zone’ – limestone is heated to approximately 800°C by direct contact with gases leaving the calcining zone. ‘Calcining zone’ – fuel is burnt in preheated air from the cooling zone. This produces heat at above 900°C and turns limestone into quicklime ...
