Show 4 optimum bed packing to be used in the rotary combustion system, whereas the air flow is varied in a range of 50 ~ 150 m3/hr. To be able to simulate the rotating speed operated in the rotary combustion system, the cycle time is then further varied in a range of 15 - 50 seconds to investigate the effect of the rotating speed on the heat recovery of the certain regenerator bed.

Since section B is divided into 4 independent compartments with two pairs of equivalent volumes, when the process VOCs-contained exhaust is introduced to section B-d (inlet) , the stream has to move upward and enter section C To be compatible with rotary mechanism of section B, section C is likewise divided into 12 compartments and those correspond to sub-section B-d and B-c enable process exhaust to pass upward and combustion exhaust to pass downward, respectively. On the other hand, section E, well packed with layers of honeycomb ceramic exhibits function of heat storage or release, is also divided into 12 compartments which connect those corresponding of section C by individual ducts of section D. Finally, the heated process |
