An improved fluidized bed reactor having a reactor shell and a reaction chamber within the shell, the reaction chamber having chamber walls and a bottom portion, the improvement comprising:
- at least one baffle disposed within the reaction chamber, the baffle comprising a pair of outer refractory walls, an inner refractory wall between and contiguous with the outer refractory walls, and a metallic reinforcement member embedded within the inner refractory wall, the inner and outer walls being attached to at least the bottom portion of the chamber.
An improved fluidized bed reactor having a reactor shell and at least one reactor subsystem within the shell, the reactor subsystem having a reaction chamber, the reaction chamber having chamber walls and a chamber bottom portion, the improvement comprising:
- at least one fluidizing gas distributor positioned beneath the reaction chamber, the distributor comprising a top portion, a bottom portion and a sidewall contiguous with the top portion and the distributor bottom portion to define an interior, the distributor bottom portion having an inlet formed therein for introducing a fluidizing gas to the interior, a plurality of tuyeres attached to the top portion of the distributor for providing gaseous communication between the reaction chamber and the distributor interior;
- and
- at least one baffle disposed within the reaction chamber, the baffle comprising a pair of outer refractory walls, an inner refractory wall between and contiguous with the outer refractory walls, and a metallic reinforcement member embedded within the inner refractory wall, the inner and outer walls being attached to at least the chamber bottom portion.
A fluidized bed reactor comprising:
- a reactor shell having a reaction chamber within the shell, the reaction chamber having chamber walls and a chamber bottom portion;
- and
- at least one baffle disposed within the reaction chamber, the baffle comprising a pair of outer refractory walls, an inner refractory wall between and contiguous with the outer refractory walls, and a metallic reinforcement member embedded within the inner refractory wall, the walls being attached to at least the chamber bottom portion.
A fluidized bed reactor comprising:
- a reactor shell and at least one reactor subsystem within the shell, the reactor subsystem having a wall and reaction chamber, the reaction chamber having chamber walls and a chamber bottom portion;
- at least one fluidizing gas distributor positioned beneath the reaction chamber, the distributor comprising:
- a top portion, a bottom portion and a sidewall contiguous with the top portion and the bottom portion to define an interior, the bottom portion having an inlet formed therein for introducing a fluidizing gas to the interior,
- a plurality of tuyeres attached to the top portion of the distributor for providing gaseous communication between the reaction chamber and the distributor interior,
- a nozzle in gaseous communication with the inlet in the bottom portion for introducing a fluidizing gas to the distributor interior, and
- a support structure having a first portion attached to the distributor and a second portion rigidly attached to the wall of the subsystem, the first portion being movable with respect to the second portion to allow the fluidizing gas distributor to move in response to variations in temperature and pressure within the reactor subsystem;
- and
- at least one baffle positioned within the reaction chamber, the baffle comprising a pair of outer refractory walls, an inner refractory wall between and contiguous with the outer refractory walls, and a metallic reinforcement member embedded within the inner refractory wall, the inner and outer walls being attached to the chamber walls and the chamber bottom portion.
An improved fluidized bed reactor having a reactor shell, a reaction chamber within the shell, and a windbox within the shell and below the reaction chamber, the windbox having a wall, the improvement comprising:
- at least one baffle positioned within windbox to divide the windbox into sections, the baffle comprising a pair of outer refractory walls, an inner refractory wall between and contiguous with the outer refractory walls, and a metallic reinforcement member embedded within the inner refractory wall, the inner and outer walls being attached to the windbox wall.
