direct fired rotary kiln dryer

Direct rotary dryers— Lift and douse the product with hot air through a parallel or counter-flow hot gas stream.Indirect rotary dryers— Heat the product from the outside, resulting in minimal contact between the product and the actualdrying gasses. This method is more suitable for dusty or very fine materials.

In adirect-fired rotary kiln, the burner is situated inside thekilnbody, that is, inside the reaction chamber. The material is heated directly by the burner flame and the stream of hot gas produced by the burner. Thesekilnsare usually lined with refractory (heat-resistant) material so that they can be operated at higher temperatures than ...

We must therefore get energy into the process as well as extract energy. This chapter examines the energy source and supply required to sustain the operation for which the dominant source is fossil fuel combustion. Herein, the basics of combustion and the flame that develops and forms the heart of thedirect-fired rotary kilnare presented.

Rotary kilnsare designed to withstand much higher temperatures than arotary dryer. Typically, if you are dealing with adirect fired rotary kiln, it isrefractorylined with a brick or castable lining. This lining protects the steel shell.Rotary dryersare typically not lined, and their steel is not able to withstand such high temperatures.
