Title: Efficient volatile metal removal from low rank coal in gasification, combustion, and processing systems and methods

Patent ·
OSTI ID:1347585
; ;

Efficient coal pre-processing systems (69) integrated with gasification, oxy-combustion, and power plant systems include a drying chamber (28), a volatile metal removal chamber (30), recirculated gases, including recycled carbon dioxide (21), nitrogen (6), and gaseous exhaust (60) for increasing the efficiencies and lowering emissions in various coal processing systems.
