What's The Difference Between Direct-Fired and Indirect-Fired
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.
Debate between Direct Rotary Dryers and Indirect Rotary …
The basic working principle of a direct rotary dryer is very intuitive and efficient. At its core, it is based on burning fuel (such as natural gas, coal, or fuel oil) to generate high-temperature gases, which directly contact the material to be dried, thereby evaporating the moisture in the material. ...
