Calcined Furnaces Circular

Calcination (also referred to as calcining) is a thermal treatment process, in presence of air or oxygen, applied to ores and other solid materials to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The calcination process normally takes place at temperatures below the melting point of the product materials

The furnaces used for calcining substances vary much in their construction, but there are three general classes: muffle, reverberatory, and shaft furnaces or kilns. Muffle furnaces (Fig. 10) are so constructed that neither the fuelnor the fire gases come in direct contact with the material to be calcined. A retort (A) of iron, brickwork, or
