Abstract
An individual cell of a fluidized bed includes a static bed disposed immediately below the fluidization region with a coal feed system, which incorporates means for igniting the coal, embedded within the static bed. Coal is fed to the static bed through a coal pipe which extends vertically upward through the bed support plate into said bed and which terminates therein in a coal distributor having a series of openings around its circumference. The coal is swirled as it flows upward through the coal pipe with resultant centrifugal force imparted to the coal ensuring that the coal will be propelled out of the openings in the distributor head and evenly distributed over the cell area.
