Abstract :
Analysis of microwave heating in a fluidized bed reactor, FBR, is presented. Simulation yields a detailed picture of selective heating by energy conversion from electromagnetic to thermal. However, particle movement and gas convection which distribute thermal radiation generated locally by microwave absorption into the volume of the FBR are not included. In order to analyze the superposition of microwave heating with convection and conduction in the FBR a unique 3D-temperature recording device has been applied. The simulated and the dynamic heating profiles are compared for an FBR filled with a microwave-absorbing material, like e.g., SiC.
