To achieve this, a direct-fired, refractory-lined rotary kiln uses a co-current (parallel) configuration, in combination with an oxygen-rich environment. This treatment, which typically takes place at temperatures ranging from 760° to 980°C (1400° to 1800°F), oxidizes the material, rendering any infectious or hazardous components inert.
These are the major differences between direct- and indirect-fired industrial kilns. I. Direct-Fired. In a direct-fired industrial kiln, the heat source is directly within the kiln itself. This means the kiln must be lined with strong refractory bricks, or a similar inner surface, to trap the heat and reflect it inwards.
