The carbon content of the residue from combustion of agricultural waste products and the fly ash content of the gaseous exhaust is controlled by regulated inflow of the combustion supporting air in a plurality of flow stream at different velocities to enhance fluidization of particulate feed in a bed being raked by a rotating sweep arm inducing radially outward movement of combustion residue into a collecting zone from which the residue enters a discharge duct. The particulate feed is dropped at location in the combustion chamber above the bed in alignment with the inflow stream of maximum velocity.

In combination with apparatus for incinerating combustible material within a fluidized bed, including the steps of: feeding the material into a fluidizing zone within which the bed is formed; introducing combustion supporting gas to said fluidizing zone in a plurality of inflow streams of different velocities insufficient to fluidize the material; continuously agitating the material to mechanically fluidize the same within said fluidizing zone during combustion and cause displacement of residual ash from the zone; and withdrawing the residual ash from a discharge location in the apparatus outside of the fluidizing zone.
