Abstract

A fluidized bed reactor includes at least one furnace section delimited by side walls and a bottom grid, the at least one furnace section provided for containing a bed of fluidized solid particles therein, and a supply for introducing a gas into the at least one furnace section at a level above the bottom grid. The supply includes (i) a gas source chamber, (ii) at least one opening in at least one of the side walls at a level above the bottom grid, and (iii) at least one conduit, having a first end connected to the at least one opening at a first vertical level and a second end connected to the gas source chamber for introducing gas from the gas source chamber to the at least one furnace section. The at least one conduit provides a solid flow preventing element for preventing solid particles from flowing backward from the at least one furnace section into the at least one conduit.
