Abstract
A fluidized bed system having a containment vessel, a precast and predried monolithic refractory floor module positioned in the vessel, and a plurality of precast and predried monolithic refractory wall modules stacked within the vessel. The plurality of wall modules includes a first wall module is positioned on the floor module, wherein the floor module and the first wall module have interlocking surfaces, and wall modules adjacent to one another have interlocking surfaces. A method for assembling a fluidized bed reactor is also provided.
Claims19
A fluidized bed system comprising:
- (a) a containment vessel;
- (b) a precast and predried monolithic refractory floor module positioned in said vessel;
- (c) a plurality of precast and predried monolithic refractory wall modules stacked within said vessel, wherein said wall modules are ring-shaped and have inner and outer circumferences, and further wherein said plurality of wall modules includes a first wall module in the form of a unitary ring positioned on said floor module;
- (d) a plurality of precast and predried monolithic refractory insulating modules stacked within said vessel and positioned about the outer circumference of said wall modules;
- (e) a dry vibratable refractory material located between the outer circumference of said wall modules and said insulating modules;
- and
- (f) a dry vibratable refractory material located between the outer circumference of said insulating modules and said containment vessel;
- wherein the floor module and said first wall module have interlocking surfaces, and wall modules adjacent to one another have interlocking surfaces.
A method for assembling a fluidized bed reactor comprising:
- (a) providing a containment vessel,
- (b) installing a precast and predried monolithic refractory floor module in said vessel;
- (c) stacking a plurality of ring-shaped, precast and predried monolithic refractory wall modules and insulation modules in said vessel, wherein said insulation modules are positioned about and spaced away from the outer circumference of said wall modules, and further wherein said plurality of wall modules includes a first wall module in the form of a unitary ring that is positioned on said floor module;
- and
- (d) installing dry vibratable refractory material in the space between the wall modules and the insulation modules;
- wherein the floor module and said first wall module have interlocking surfaces, wall modules adjacent to one another have interlocking surfaces, and insulation modules adjacent to one another have interlocking surfaces.
A fluidized bed reactor comprising:
- (a) a containment vessel;
- (b) a precast and predried monolithic refractory floor module positioned in the bottom of said vessel;
- and
- (c) a plurality of ring-shaped, precast and predried monolithic refractory wall modules stacked within said vessel, wherein said plurality of wall modules includes a first wall module positioned on said floor module;
- (d) a plurality of ring-shaped precast and predried monolithic insulating modules stacked within said vessel and positioned about the outer circumference of said plurality of wall modules such that an annular space is provided between the plurality of insulating modules and the plurality of wall modules;
- and
- (e) a dry vibratable refractory material that fills said annular space between the plurality of insulating modules and the plurality of wall modules;
- wherein the floor module and said first wall module have interlocking surfaces such that an interlocking joint is provided between the floor module and the first wall module, and wall modules adjacent to one another have interlocking surfaces such that an interlocking joint is provided between adjacent wall modules;
- and further wherein each of said wall and insulation modules comprises either (a) a unitary ring, or (b) two to five monolithic ring segments joined to one another along interlocking sidewalls, with said first wall module comprising a unitary ring.
