| 摘要 |
A heating and fluidization system for air fluidized sand beds, and associated methods, are disclosed. Control of a heat input is separated from control of a fluidization rate to optimize simultaneously both the amount of heat entering the system and the heat transfer rate. In at least one embodiment, the system includes: a heating tube configured to receive a heat input from a heat source and to provide the heat input to a media in a bed at a first predetermined, optimized rate; and a fluidization tube disposed, generally, below the heating tube and configured to provide a fluidization rate to the media in the bed at a second predetermined, optimized rate, thereby adapted to control fluidization and to maximize heat transfer. The heating tubes can include spines to increase surface area and maximize heat transfer. The fluidization holes can be covered by nozzles to direct the fluidization.
