Coal is the major fuel for power
generation in the world and is the major emission source
of both global and local air pollutants, e.g., CO2, SO2,
and particulates. Clean and efficient utilization of coal
is a major undertaking in energy technology development.
 The
PAI Circulating Vibrated Bed (CVB) technology mixes
pulverized coal particles with hot ashes discharged from a
power plant furnace. Liquid fuel is evolved in the form of
gases, which are condensed by heat exchangers.
Noncon-densing gases are sent back to the furnace for
burning.
Cold tests
of the CVB system have been successfully per-formed in the
PAI laboratory, and a hot test system has been designed.
