Fluidized beds provide excellent mixing and homogeneous temperature distribution throughout the reactor allowing sustained lower temperature operation and no hot spots. Fluidized beds often allow improved handling and transportation of hot solids among various process steps. Many fossil fuel utilization processes could benefit from incorporation of fluidized bed technologies including transport coal gasification, gasification of low rank coals, sulfur sorbent regeneration, hydrogasification, oxycombustion, and CO2 capture to name a few. NETL’s cold flow facility can be used to study the properties of fluidized beds. It is the largest such facility in the public domain in the country. It is being used to investigate the hydrodynamics of various fossil fuel utilization technologies. The advanced instrumentation in the cold flow facility can be used to collect information that can then be used to validate predictions made using computational fluid dynamic models of fluidized beds.
