Abstract:
A method and apparatus for fluidized bed construction in which the fluidized bed is confined in an annular combustion chamber and fuel is injected into the lower portion of the fluidized bed by a centrally located whirling disk having vanes thereon for impelling the fuel and secondary air laterally outwardly. Primary air is provided from a blower jointly driven with the fuel distribution disk and supplying air under pressure to pass upwardly through air supply openings in a grate forming the bottom wall of the combustion chamber, with the jets of air passing through the openings having upward and tangential components of movement so as to impart rotary motion to the fluidized bed in the annular combustion chamber.
