Table 14.3 Characteristics of Selected Feed Materials Tested in Novadyne Pulse Combustion Dryer...

Figure 23.15 shows the flow diagram of one prototype pulse combustion dryer designed by Novadyne Ltd (Canada) (Kudra and Mujumdar, 1995, 2002 Kudra et al., 2003). In the flash dryer configuration, the unit consists of a pulse combustor, a pneumatic duct that extends from the tailpipe of the pulse combustor, and devices for materials feed and discharge. The pulse combustor uses a self-actuated flapper valve, and its operating frequency is about 70 Hz. The rated capacity of the combustor equal to 300 kW offers an evaporative capacity of about 275 kg/h of water. Wet particulate materials such as sawdust, hog fuel, corn fibers, or spent coffee grounds are injected directly into the tailpipe...
