'''Fluidized Bed ApplicAtions And VAlidAtion'''
Background
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.
