Cloots, H R

A fluidized bed combustion apparatus is described comprising: wall means defining an annular combustion chamber having a substantially vertical axis and a coaxially extending central opening; grate means extending horizontally across the lower end of the combustion chamber and formed with a plurality of air supply openings therethrough; disk means mounted for rotation above the grate means about an axis coincident with the vertical axis of the combustion chamber; a bed of non-combustible particulate material in the combustion chamber above the grate means; air supply means formed for forcing air under pressure upwardly through the openings in the grate means to fluidize the bed; drive means operatively connected to and formed for rotating the disk means; and fuel feed means at the central opening in the wall means formed for depositing fuel on the disk means whereby rotation of the latter centrifugally distributes the fuel into the annular combustion chamber above the grate means.
