Apparatus for supporting a perforated plate air distributor for a fluidized bed

摘要

Apparatus for supporting a perforated plate (24) air distributor for a fluidized bed combustion boiler. The plate (24) is supported (26) around its entire periphery, and at given points (42) within its periphery, in such a manner that it is free to expand due to thermal growth in a horizontal direction, while still being capable of supporting a vertical load (12) without sagging, buckling, or being subject to failure.
