ABSTRACT:
The rotary stoker has a fuel supporting grate which is divided into a central stationary section and an outer rotating ring. Fuel is fed to the center of the stationary section. The outer ring is downwardly and centrally inclined, as an inverted cone, and lies partially beneath the stationary section to form an annular trough of V-shaped cross section. Openings or spaces separate the stationary section and outer ring, in the bottom of the trough, for continuous ash removal into a hopper as the ring rotates. Air may be admitted through the under sides of both sections of the grate from separately controlled air plenums. Air may also be admitted above the grate from a third, separately controlled air plenum.
