A system and method for controlling the sealing efficiency and recycle rate in a fluidized bed reactor in which air is introduced into two chambers found in a sealing vessel for receiving the separated solids from the separator. The air is introduced into two chambers in the sealing vessel in a direction opposite to that of the flow of the separated solids through the vessel. One of the chambers is located below the separator dipleg and in alignment therewith and the other chamber surrounds the first chambers. The air flow through each path can be separately adjusted as necessary.

A fluidized bed combustion system including separating means for receiving a mixture of flue gages and entrained particulate material from fluidized bed and separating said entrained particulate material from said flue gases, means for passing said separated flue gases from said separating means to a heat recovery unit, a seal vessel, a dipleg for passing said separated material from said separating means to said seal vessel, means for passing said separated material from said seal vessel back to said fluidized bed, and means for introducing air or gas to said seal vessel for fluidizing the separated material in said seal vessel to seal against the backflow of said separated material from said fluidized bed, through said dipleg and back to said separating means, said air introducing means comprises a first conduit for introducing air or gas into said seal vessel in a path aligned with the flow path of said separated material from said dipleg, and a second conduit for introducing air or gas into an area of said seal vessel surrounding the flow path of air or gas from said first conduit.
