Abstract
A transfer pipe system for transferring particulate bed material from a fluid bed reactor includes a discharge pipe connecting the fluid bed reactor with a vertical transfer pipe, gas injection nozzles for fluidizing particulate material within the transfer pipe and a standpipe connecting the transfer pipe and the freeboard region of the fluid bed reactor to vent fluidizing gas from the transfer pipe into the freeboard region and so avoid introducing a high velocity, counter-current gas flow into the discharge pipe.
