Reh diagram

To understand the interplay between the fluid bed and moving bed in the INCI concept, the Reh diagram was used to investigate the influence of agglomeration.

The Nyquist plot in a complex-plane diagram of the Randles cell with capacitor replaced by a CPE is a depressed semicircle, as shown in Figure 4.136. If co —> the intercept of the depressed semicircle at the real axis equals Reh and rf m — 0, the intercept equals the value of Rei + Rct. The deviation of the n value describes the... 

Fig. 5-33. State diagram of gas/solid systems simplified for fluidized beds range of operation by Reh [5.54-5.56], Representation according to Poersch, Fa. Babcock-BSH AG, Krefeld.

Reh [138-140] established a diagram to illustrate the states of gas-particle interactions on one glance. This is very useful in understanding the operation ranges of gasification systems especially if particle segregation (e.g., agglomeration) effects occur.
