ABSTRACT:
The specification discloses a flow distributor for distributing a flow of fluid to a bed of particles in a fluidized bed reactor. The flow distributor comprises a plurality of spaced apart discharge conduits containing exit openings for distributing the flow of fluid into the bed of particles generally across the width of the reactor from a plurality of spaced apart locations. Flow diffusers are located in the conduits upstream of the exit openings to provide multiple, spaced apart, generally parallel, flow streams within the conduits which expand and merge together as they approach the exit openings to produce a merged flow stream extending substantially across the width of each conduit prior to discharge of the flow into the reactor. The multiple flow streams within the conduits expand the flow in the conduit more quickly than a single expanding flow stream from a single opening, so that the length of the conduit may be shortened while still providing full expansion of the flow across the width of the conduit to decrease the velocity of the fluid before the flow exits the tube into the reactor.
