A support plate of a fluidization reactor grid is mounted in the body of the reactor between a support bracket and a ring, both of which extend around the inside of the reactor, and which are spaced apart to define an annular space in which the periphery of the support plate is located. This mounting is made leakproof by two seals between the support plate and the bracket and the ring, one of which seals is clamped so that it expands between the support plate and the bracket.

A leakproof mounting device for a support plate of a grid of a fluidisation reactor comprising a one piece grid support plate, a peripheral bracket mounted inside the reactor on its inside peripheral surface, a peripheral ring also mounted inside the reactor on its wall spaced from said bracket form

A leakproof mounting device for a support plate of a grid of a fluidisation reactor comprising a one piece grid support plate, a peripheral bracket mounted inside the reactor on its inside peripheral surface, a peripheral ring also mounted inside the reactor on its wall spaced from said bracket forming an annular space bounded in height by said peripheral ring and said peripheral bracket, and by an inner wall of the reactor between said ring and said bracket, annular seals respectively disposed on both sides of said plate in annular spaces separating said plate from said bracket and said ring, said lower seal and said bracket supporting said plate with a slight radial clearance relative to the inside wall of the reactor, means to clamp said lower seal to expand said lower seal in its direction between said plate and said bracket, said clamping means including wedges which are substantially contiguous annular segments along a circumference of said lower seal, and clamping screws located to clamp said lower seal against said wedges.
