[Gasification] Fluidised bed reactor

Thanks. I had forgotten the Kalle charcoal gasifier Has anyone built one in recent years to verify the performance?

Flue gas is sometimes recycled in a fluidized bed combustor to control peak temperatures to prevent slagging and NOx emissions. I haven’t gasified charcoal in a fluidized bed.

..hum, you wanna take a closer look at how the Källe gasifier
recycled 18% of the engine exhaust gas to save ~20% fuel, and
how that recycled heat made the gasifier run cooler. ;o)

..I see the Källe gasifier ran 17%, a type of wood gasifier 
used Norway (or Finland?) used 18%, good starting points for
further research.
