Rotary Reactor Engineering

This type of rotary reactor is usually called a rotary kiln and is applied to decompose and sinter a variety of inorganic feed stocks. Thermal energy in the exit gas from the rotary kiln is recovered by application of a preheater. In the preheater, a countercurrent exchange of heat takes place within a vertical moving bed.
